Venice: City of Bridges- Guest Column

There are two different types of historic bridges: One that stands out in terms of its design and history and one that integrates itself in a setting, where if visited, one can experience the culture that both the bridge and the area surrounding it offer. One cannot modernize with a new crossing without understanding the implications they have with the neighborhood or landscape. And this is where this guest column comes about.

I happened to stumble across this column by accident and wished I hadn’t for I have yet to visit Italy and explore some of the finest bridges in the country. Italy is home to thousands of crossings dating as far back as the Roman Empire. This include some of the bridges that were built before and rebuilt after the fall of the Empire, including some by King Theoderich (see my article on this topic), such as the aqueducts in Rome (as described in another article here.) Then there are the bridges serving the waters of Florence……

….and this city, Venice.

Home to over 2.5 million inhabitants (with 260,000 living directly in the city center), the city is home to over 430 bridges, including two of the most famous landmarks of the city: The Ponte di Rialto and the Bridge of Sighs. Both of these bridges, dating back to the late 1500s, are part of the majority that can be easily reached by boat or gondola. A guide to the highly recommended bridges to visit in Venice can be accessed by link here.

Yet this guest column written by a columnist who focuses on life in cities and sunsets, puts together Venice’s historic bridges with the colorful faces that the city has to offer. It is a long column about her adventures through the city, and her impressions lead to readers like this one to add this city to the places to visit and bridgehunt- very high up in the Top 3. To look at Venice’s bridges, have a look at the summary below and click to read to the end. When done, you will not regret it like I didn’t but more like provide an incentive to go there and have a look. Enjoy! 🙂

The city of bridges, as it is fondly known, is everything you would imagine it to be. It has a surreal feeling when there, living up to all of its stereotypical features; pretty bridges over winding canals, narrow paths nestled between old tall brick buildings, gondolas and motor boats carrying fruit and vegetables, singing gondoliers […]

Thought of the Day: Maintenance is Preservation

23722448_1733664680040481_644604215249984068_n

This photo was taken by fellow pontist Will Truax which needs no explanation. This sign can be found at the Springfield Armory in Massachusetts, which is a National Historical Site. Albeit not a historic bridge, you can find our more about its history here. This saying applies to all historic places, inlcuding bridges, something that we seem to forget nowadays, in the age of modernization and waste.

Some Food for Thought! 🙂

What’s in a Name? a Guide to Naming Bridges (And Other Things)

186994-l

What’s in a name? Somewhere in New York City, a new set of twin bridges will be named after New York Governor Mario Cuomo for his years of service in the Big Apple, the state and in the Republican Party. It would be the 12th bridge in the metropolitan area to have been named after a famous person, including the two well-known American politicians. Despite leaving their marks on their legacies, what in a name?

 

What’s in a name?  In states, like Oklahoma, bridges have been named for politicians who wanted to be famous during their time in office, but whose political careers were marred by scandal. They include the likes of Henry Simpson Johnston, Frank Lynch and Raymond Gary- the first was impeached and thrown out after two years as governor; the second took kickbacks while representative and the other “bought organs for the churches and pianos for the bawds,” as the secretary used in her title of the biography, bashing the male half of the husband-wife team. What’s in a name?

 

What’s in a name? Somewhere in the United States, bridges are being conceived and names are being brought up after current members of Congress and the White House. Whether it is a suspension bridge spanning the Minnesota River east of Granite Falls- making it the longest in the world- named after Paul Ryan, a piece of slab bridge over the Ohio River in Cincinnati named after Mitch McConnell, A concrete deck cantilever bridge with a marble statue named after Donald Trump in Washington, and even a series of cable-stayed bridges with a mermaid statue resembling Ms. Conway. These people are famous for undoing the legacy of President Obama that had benefitted much of the American population, almost all of whom think these people deserve to get the boot earliest after the Congressional Elections next year, which if Democrats retake Congress by the widest of margins, impeachment, and call for new presidential elections will definitely be on the table.  What’s in a name?

186993-l

What’s in a name? In Pittsburgh, three sister bridges, each built in the late 1920s, each having a similar design, are named after three local but national favorites: Rachel Carson, Andy Warhol and Roberto Clemente, each setting their marks in the areas of environment, arts and sports respectively; each one has posters, statues and other decorations served in honor and memory. Each one we remember in our history books. What’s in a name?

 

What’s in a name? Many bridges are named after famous people, yet 75% really were not that famous, unless you are thinking of “dollar and sense.” If we look at each sign on the structure, we sometimes have to ask the following questions: 1. Who were these people? 2. How did they leave their mark in history? 3. Was their legacy beneficial or a hindrance? If we look at the bridges that were named after unknown politicians, many of us don’t even know who they really were, let alone don’t want to even know about them because of corruption, scandals and other policies that harmed the American public and our allies. Is our history becoming based on how politicians perform “on stage” on Capitol Hill? Let alone in our state legislature?  If so, then may the most attractive jobs in America be a politician, for like lawyers (many, not all of them), they love to lie, deceive, gaslight and even rob the common person, regardless of social, ethical, religious and psychological backgrounds. If we want that, then we might as well have bridges named after Hollywood film stars who have done the stuff politicians have done, for it would have the exact same effect.

183930-l

When I think of America, I think of the people who really did make a difference in terms of transforming the country to what it is today. I think of Giovanni de Verrazano who discovered New York, and whose bridge, Othmar H. Ammann’s last prized landmark before his death in 1965, was named after him. That bridge is still connecting Staten Island and Brooklyn. I think of Daniel Boone, who opened the new frontier for settlers. There had been a bridge named for him before it was imploded in place of a new bland concrete slab bridge in 2016. I think of George Washington, who led the colonies to victory, presided over the Constitution and was our first president. While there were several bridges named after him, many are being wiped off the map. The same applies to other structures named after the founding fathers.  And while we have several structures named in honor and memory of the veterans who fought in the wars, the aesthetic value is really bland in taste and the artistic value has really gotten lost in the pile of steel and concrete.

 

Have we lost our true value of our culture, our history and even our identity?  Have we given up too much of our freedom and creative talents to make the best for others, while giving the narccists who have done nothing good the honors they don’t deserve?  Have we forgotten the concept of being honored for our own merits?  When I look at the bridges named after Rachel Carson, Roberto Clemente and Andy Warhol in Pittsburgh, I see the reason behind them getting their honors, for they contributed to shaping American society to what is still is today. Even having bridges named in honor of Stan (the Man) Musial and James Eads in St. Louis are justified, for the former left his mark in baseball and the latter for creating the first steel bridge in America. Have we seen politicians contribute as these people have done? The answer to that question is, in my humble opinion is no, with only a few exceptions.  It’s really time to take a look at how we honor our people. Do we honor them because of money and power or because they carry a certain title? Or do we honor them for their merits and contributions to American society?

177200-l

Each of us has our set of guidelines. Mine would be on the basis of creating and innovating things that have contributed to America in terms of science and technology, history, culture and society. I hope you all have the same ideas as I do, if we really want to move forward as an entity that should be setting examples for other countries.

 

And while my ( not yet honored) candidates would make up a quarter of the country’s population, I have my top five who deserve to have their bridges named after them, and I hope the designs will be more appealing than just having green road signs at each entrance. My top five would be:  Barack Obama, Red Cloud, Thomas Edison, Steve Jobs and Othmar H. Ammann. Honorably mentioned would include Yogi Berra, Lou Gehrig, Sally Ride, Vince Lombardi, Carrie Fisher, Sinclair Lewis, Garrison Keillor, Charlie Wilson, George HW Bush, Harper Lee and Massasoit, just to name a few. We need a few crossings but not necessarily new bridges. We just need to be sensible as to naming the next bridges after famous people.

 

And so, for the Fourth of July, I must ask you: Who would deserve to be honored on a bridge and/or other places? Think very carefully before deciding…..

 

The  Bridgehunter’s Chronicles and sister column The Flensburg Files would like to wish all Americans at home and abroad a Happy Fourth of July. Think of the people who made a difference for this country and how it set an example for others.

 

God bless you!

The Bike Challenge

Co-produced with sister column:

In the past few weeks, three out of four of us have been nominated for the Ice-Bucket Challenge, whereby of the 75%, four out of five of us have actually done this challenge, either by donating $100 or dumping the bucket of ice water on our heads and donating an amount of our choice to the cause, which is fighting ALS. This disease, also known as Lou Gehrig’s Disease, disables the nerves and spinal area in the body, affecting the person’s motor skills.

The disease was named after the famous New York Yankees baseball star, who retired 75 years ago after being diagnosed with the disease and died less than two years later. He was the player famous for his comment: “Today, I consider myself the luckiest man on the face of the Earth.”

The idea of the bucket challenge came from Bill Gates and has received mixed reviews from those willing to present themselves doing this rather absurd act on social network and those who think society has become dumber by doing this. Personally, it would not be my cup of tea, as there are other crippling diseases that are just as deadly as ALS. This includes Multiple Sclerosis, a degenerative muscular disease that kills a person just as tortuously as this one. This is speaking from the experience after losing a close relative and two friends to this disease. And even if there was a bucket challenge for MS, I would go for the $100 donation instead of suffering from hypothermia thanks to a large bucket of ice cold water. Sorry people.

But the ice bucket challenge presented a brilliant idea for another fundraiser- the bike challenge. With the increase in popularity of bikes and the proliferation of bike trails both in the US and in Europe, why not use the bicycle as the challenge for raising funds?

The idea is simple.

One can challenge someone to bike a certain amount of kilometers and donate an amount of choice. Yet if he/she refuses, then a fixed amount would have to be donated, just like in the ice bucket challenge. The person would have to provide photos and tracking information to prove that the kms were biked and pass the challenge to others who are either avid bike fans or are willing to take up the challenge.

For example:  If I was challenged to bike 50 km in one day, I would pick and choose a route that is bike friendly, like the bike trail along the Unstrut River in Thuringia between Erfurt and Artern, for example. Then I would provide a tracker and some photos, and after doing so, would challenge my next three compatriots to do the same. The amount donated can be based on whether I fulfill the challenge (which would be a fixed amount in my favor) or if  I pass and have to donate based on what was fixed by the organizer, as Bill Gates did with his ALS Challenge.  By the way, I did take the challenge a couple weeks ago, as you can see in the pics here.

A railroad bridge converted to a bike trail crossing at Artern.

Such a bike challenge is useful for not only fundraising drives to combat diseases, like MS or cancer. Yet it can be useful for projects to restore historic places, like bridges, churches and houses, and other causes. For grassroots groups seeking fund-raising posibilities, this challenge is healthy, affordable and provides a challenge to those who would take advantage of the great outdoors and provide a sense of personal achievement, instead of making a total fool out of him/herself by dumping a bucket of ice water over the head, risking a heart attack, hypothermia and other health issues. Furthermore, as you can see in my challenge, you can discover many new sights based on your interest (and the interest of others)

So if you are one of those groups seeking fund-raising possibilities and would like to challenge people, this is one worth considering. It runs parallel to the ice-bucket challenge, but it is a lot more interesting, fun, healthier and even safer than the other challenge. And even if you decide for another challenge- like a friend of mine from Minnesota did and thought of a creative way to challenge others to buy extra products to be donated to a local food shelter- it is much more beneficial than to be soaked in ice cold water, especially now, as my instincts are telling me that winter is coming much sooner than expected. It is already cold and fall-like, with snow already falling in Rapid City, South Dakota– not typical of September weather and something where the ice bucket challenge is not a good idea to begin with. 😉

Author’s note: The Bridges of Unstruttal will be featured later in the fall/ winter, as the author has yet to complete the second half of the leg from Artern to Naumburg. In the meantime, enjoy the preview of what is yet to come.

 

In School in Germany: The Pocket Guide to Industrial History

Rendsburg High Bridge in Rendsburg, Germany Photo taken by the author in April 2011

 

Joint article and forum with sister column the Flensburg Files in conjunction with the series on In School in Germany. Except this example focuses on Infrastructure, using Historic Bridges as an Example.

A while back, shortly before my debut teaching about industrialization in the US and Germany between 1870 and 1914, I had put out a question as to how to approach the topic of infrastructure in that era, in particular when it comes to bridge building, and how it ties in with the usage and proliferation of the material of steel- a replacement to iron. For more information on this inquiry, please click here for details.

Here is the follow-up on this particular topic, which has me thinking about a creative way of getting students acquainted with infrastructure and industrialization:

During the block-session, which consists of two 45-minute sessions into a 90-minute one, students had an opportunity to write down their notes in a small pocket brochure, compiled on my part. This is what the pocket brochure looked like:

The notes to be taken by the students (consisting of high school juniors) were in connection with a series of mini-presentations that they were supposed to give, based on the following topics that were given to them to prepare two weeks beforehand:

Iron and Steel

The Great Chicago Fire of 1871

The Chicago School of Architecture

Railroads

Bridges

Canals

The Automobile

The Roads

Inventions (Electricity, the Telephone, etc.)

Each presentation was 3-5 minutes long, with questions to follow.  The exception to the topic was the one on bridges, presented by yours truly.  The topics were presented in a way that materials go first, for they played hand-to-hand in the development of other forms of infrastructure and transportation.

The results were astounding. Lots of information on American and European inventors making their marks, yet one would need a couple more sessions to digest all the information presented.  Some questions in connection with this topic you can find in the Files’ article here.

The problem with presenting infrastructure and industrialization is that the development of both Germany/Europe and the US was exponential, that it would be difficult to cover everything. It even applies for bridges, as dozens of American and European bridge builders were responsible for hundreds of bridge designs and bridge examples that existed during that time (and still do today). Plus some of the bridge builders of that time period had their own colorful history that is worth mentioning; especially when it comes to those immigrating to the US from what is today Germany, Poland, Austria, France and Hungary (where they were once known as The French Kingdom, Prussia and later the German Empire, Austro-Hungarian (or Habsburg Empire) and the Russian Empire (as Poland became part of the empire in 1795 as part of a partition agreement with Prussia)).

The end result was a compromise presented by the history teacher upon evaluating the session: a pocket guide to certain aspects of infrastructure with a focus on a country and some key examples worth noting. If divided up into the aforementioned topics, it would make the most sense, as for each aspect, one can present some key facts that are relevant to the topic of infrastructure and industrialization, along with some fun exercises . Plus if the booklet is 10-15 pages per topic, it will be sufficient enough for pupils to get a whiff of the aspects of history that have been left at the wayside, while the remaining artefacts become a distant memory,  but at the same time, be encouraged to preserve what is left of history or take measures that matter to them. After all, when we talk about environment and protection, our heritage technically belongs to this fragile umbrella.

For the pontists and historians alike, some ideas of how to construct such a booklet pertaining to bridges is a tricky one, for especially in the United States, the topics and the number of bridge builder and bridge examples have to be narrowed down to only a handful of examples. So if we look at the proposal for such a booklet for Germany, we have the following:

Part I: German emigrants- focusing on John Roebling, Albert Fink, Gustav Lindenthal, Wendell Bollmann, Joseph Strauss und Lawrence H. Johnson

Part II: German bridge engineers (who stayed in Germany)- Friedrich Voss, Hermann Matthäus, Gustav Eifel, Hermann Gerber, Franz Meyer

Part III: Areas of bridge building- Cities (Berlin, Hamburg, Frankfurt, Halle (Saale), Leipzig, etc.- choosing three; Canals (Baltic-North Sea, Dortmund-Ems, Elbe-Lübeck) and a pair of River Examples

Part IV: Notable Works- using two bridge examples, like the Rendsburg High Bridge, for example, and presenting some interesting facts about them.

If you were asked to construct a booklet similar to the one mentioned here, for the US, how would you structure it? What contents would you put in there and what examples would you include?  You can place your comments here, on the facebook pages under the Flensburg Files and/or Bridgehunter’s Chronicles, or in the LinkedIn page under The Bridgehunter’s Chronicles.  Do not be surprised if you have a question coming from either the author or one of the readers pertaining to a booklet on a similar topic but pertaining to Canada or another country.

Those wishing for a copy of the booklet I made for my history class or a power point presentation on bridges in Germany and the US can contact Jason Smith at the Chronicles at flensburg.bridgehunter.av@googlemail.com. Please be aware that both are in German and that if you want the English version, you will have to wait a couple weeks.

And now to the Files’ Guessing Quiz pertaining to Industrial History, which you can click on here.

The Oldest Bridge Book

Question for the Forum:

Here is an interesting question for you readers to start off with:

What was the oldest known bridge book you have ever read? When was it written and what was the title?

Do you know about a bridge book that is the oldest ever written?

There is an explanation that warrants this question for discussion:

I’ve been quite busy with my latest bridge project I’m doing for a history professor at the University in Jena, Germany on Roman Aqueducts, focusing on the reconstruction of the ones in Italy after Theoderich the Great took power in 493 AD. Going through the sources to find enough information can be a chore, as a there are a few books about this topic, not to mention some of the inscriptions in Latin that had to be deciphered into English to determine when the aqueducts were built, let alone rebuilt upon orders of the Goth. As I was going through the work, I happened to find a book on Roman Aqueducts, located right in the library at the University!

The author of the book is Esther van Deman and the title: “The Building of Roman Aqueducts” It featured nine examples of aqueducts that were built between 20 BC and 250 AD, with four of them being rebuilt after 476 AD, when the Western Roman Empire ceased to exist with Odoacre taking power in Italy. It also featured the art of constructing them, using various materials ordered by the emperors, beginning with Augustus, and designing them using the stone or brick arches that were engineered by the Roman builders with the goal of bringing water to the region. After all, the Romans needed water for all sorts of purposes, including the public baths in many cities, irrigation, plumbing, and even drinking.

But when was this book published?  1984?  1977?   1966?

1934!!!!

The Carnegie Institute of Washington, DC published this work, which contained information and photos eighty years ago! This meant that with the exception of bridge examples presented by the bridge companies, like King, Wrought Iron Bridge, Clinton, or even the ones in Canton, Ohio or Pittsburgh, bridge books were being produced at least eighty years ago, with photos and all. But was this book the oldest ever published?

Doubtful!   My assumption was the book on the Great American Bridges by Donald Jackson was the oldest one ever written about (historic) bridges, being published in 1984- fifty years later. Yet I also discovered a couple more books written a year later about bridges in Pennsylvania and Australia. Yet if my assumptions are wrong by sixty years, then this means that there were many books- ancient ones- that had existed before that.

So let’s start with the forum by answering the questions I brought forward at the beginning: the oldest book you have written and the oldest known book that exists about bridges. Place your comments here or through the social network pages bearing the Chronicles’ name, with hopes that other stories will come to light.

As I’m on the same page regarding Roman Aqueducts……

 

The Bridges of Lübeck, Germany

Hub Pedestrian Bridge. Photo taken in October 2013

Lübeck, Germany. The home of marzipan. The home of Medieval and Baroque architecture. Situated just west of the historic boundaries that had once separated East and West Germany  but is today Schleswig-Holstein and Mecklenburg-Pommerania, the city of 230,000 inhabitants, the second largest city in the state behind Kiel, is home to two universities, and is a magnet for tourists, as it is only 15 minutes by train south of the Baltic Sea on the Trave River. As it has three rivers and a pair of man-made canals in and around the historic Old Town (declared a World Heritage Site by UNESCO), it is not surprising that the city has one of the most populous bridges in Germany, ranking up there with Hamburg, Berlin, Erfurt and Nuremberg, just to name a few.  As many as 230 bridges are known to exist in Lübeck as well as the neighboring beach community of Travemünde. 19 of them are located in and around the historic Old Town, spanning the Trave River as well as parts of the harbor and the Lübeck-Elbe Canal, which tangents the Old Town to the southeast before going south towards the Elbe at Lauenburg, 80 kilometers south of the city. That canal was built between 1895 and 1900 by Peter Rehder, whose bridge in Lübeck is named after him.

Just recently, I had an opportunity to visit these bridges as part of our tour through Lübeck with my wife and daughter. Many of these bridges can be seen via boat while others are within 5-10 minute walking distance inside the Old Town.  Many of these structures have survived the onslaught of World War II, where 30% of the center was destroyed by air raids. Others were built in a fashionable way 15 years ago.  In either case, this tour will take you through the old town and to each of the bridges and their histories. Photos of the bridges can be viewed by clicking on the name of the bridge.  One of the bridges, the Herrenbrücke, will be featured in a separate article, for a book was written on the double-bascule bridge, which has been replaced by a tunnel.

We’ll start with the Canal Crossings before going to the Trave River ones.

Lübeck-Elbe Canal:

Hub Bridges:  The first crossing along the Canal is located at the mouth leading into the Trave River. The bridge features three different crossings, each measuring between 42 and 45 meters in length. Two of them are hydraulic vertical lift spans, each featuring riveted Parker truss spans. The river side of the bridge used to serve rail traffic which ran along the river before it was discontinued in the 1980s. That crossing was later fixed in an elevated form and left there to allow ships to continue passing through. The center portion of the bridge is open to vehicular traffic and connects Unter der Trave with Hafenstrasse. This still functions as a hydraulic vertical lift bridge today and, as you can see in the video here, one can see the span be hoisted in 2-3 minutes’ time from the neighboring Burgtorbrücke. The pedestrian bridge on the canal side is a steel through arch bridge with portal and strut bracings similar to the now extant Fort Keogh Bridge in Montana (USA). That crossing is the only fixed span built when the three crossings were built between 1896 and 1898. Rehder and C. Hoppe were the contractors for the three crossings as they were built as part of the five-year project to canalize the city. Despite the railroad bridge being decommissioned, the crossings are clearly delegated to pedestrians, cyclists and car drivers to ensure their safety in crossing the structures. The tower located next to the three bridges serves as the control station for the center span. Its fancy Baroque design matches that of the architecture one can see in Lübeck.

Here are the links to the photos of the three crossings:

Railroad Through Truss

Vehicular Through Truss

Pedestrian Through Arch

 

Burgtorbrücke-  At 210 meters, the deck cantilever truss bridge using a Pratt truss design, is the only bridge in the city’s history to originally be built to span the Wakinitz River before the Canal was built in 1898. The original bridge was supposedly built in 1806 connecting the Old Town at Burgtor with the northern part of the city where Gustav Radbruch Platz is now located. The span was later replaced in 1898 with a cantilever suspension bridge that was three times the length of the original span and with the same height as the present-day structure. That bridge was replaced in 1910 with the present structure and since that day, has continued serving traffic on the east side of the city, connecting the Old Town with Travemünde and points to the north and east. The nearby Gustav Radbruch Platz is the eastern hub for all bus services serving the city and beyond.  The concrete lion statues, conceived by artist Fritz Behn in 1913, were placed at the northern portals of the bridge in 1931 and are a site not to miss, together with the concrete ornamental railings and the Burgtor Gate that is located right next to the bridge to the south.

Klughafen Pedestrian Bridge- In an earlier article posted on the Chronicles (click here), we had a pop quiz to ask you when the bridge was built and whether this bridge is movable or not. The answer to these two questions took even the author by surprise, given the nature of how the boat tour guide told the story. While the trusses may have indicated that it was built 100 years ago and it was rehabilitated 15 years ago, it was actually built in 1994. And while the vertical beams holding the center span indicate a potential vertical lift bridge that would have been one of a kind, it only serves as a way of keeping the span from falling into the canal. Hence the comment that the bridge “was a decoration” serving pedestrians. Yet the almost 20-year old is beset by problems to be addressed by the city council, and that is vandalism by spray-painting. Instead of the pine green color it presents, the bridge is covered with various colors and shapes, some of which are deemed inappropriate. It will not be surprising if this pedestrian bridge receives a makeover in the coming years ahead.

 

Hüxtertorbrücke- No German city is not complete without this type of bridge: a steel arch bridge whose upper chord represents Pratt trusses curving from one end to another.  One can find this bridge in cities like Munich, Berlin, Leipzig and Cologne (the last city is famous for its Hollernzollern Bridge). Plus there were some that had existed in places, like Kiel, before they were razed in favor of more modern bridges. The Hüxtertor Bridge, named after the gate that was destroyed in World War II and is now dominated by the Discothek, is one of the smaller of these bridge types. It was built in 1927 and is a pony arch bearing a pale lime green color. It features typical 1920s style lighting supported by concrete towers. The bridge carries Hüxterdamm, connecting the city center with Falkenplatz and its adjacent Volkshochschule (Institute of Continuing Education).

 

Rehderbrücke:  Located next to Hüxtertorbrücke on Krähenstrasse, this bridge was named after the man who built the canal but was built in 1936. The bridge type is deck plate girder with cantilever features, and the black bridge’s typical feature are the rollers on the concrete piers. These not only support the bridge itself, but they serve as devices for expansion (during the warm months) and contraction (during the cold months).

Mühlentorbrücke:  Apart from the Burgtorbrücke, this bridge is one of the most ornamental bridges built of steel that had existed in Lübeck before World War II. The bridge was built at the time of the construction of the Canal (1899-1900) and featured finials on towers that included ornamental lighting on it. The bridge itself is unusual in three ways: 1. The towers are supported by prefabricated curved steel beams which is also hold the vertical suspenders that attach to the road. It is not an eyebar suspension bridge, like the Three Sister Bridges of Pittsburgh, for these steel encased cables are stiff providing more tension to the top part of the bridge. 2. The roadway supported by the steel beams is diagonal to the towers that are built parallel to the riverbank. With the exception of the Swinemünde Bridge at Gesundbrünnen Station in Berlin (which is cantilever), the Mühlentor Bridge is one of the rarest suspension bridges that has such a unique feature.  3. And while there is no horizontal beam supporting the towers, like other suspension bridges, this bridge also features cantilever deck trusses as the support for the decking, rendering the towers and encased cables as useless. Henceforth this bridge is unique in itself and will most likely be considered a national landmark if it has not happened already.

Possehlbrücke-  The last bridge along the canal is the Possehlbrücke. Built in 1956, the bridge is a prestressed, and pretensioned concrete girder bridge serving Possehlstrasse between the Old Town and points going southwards. The bridge represents a classic example of concrete bridges that took too much vehicular traffic resulting in cracks in the concrete superstructure and other structural issues. Albeit restricted to traffic up to 7.5 tons since 2012, the bridge’s days are definitely numbered. Earlier this month, the city council voted unanimously to demolish the structure in favor of a new structure. Construction will start in Spring 2014 and will take over a year to complete. Tourists travelling by boat will be seeing cranes and diggers at the site in the coming year instead of the picture the author took.

Trave River:

Wipper Bridge and the Cathedral.

Wipperbrücke- Spanning the city arm of the Trave River as the first crossing entering the river, this 1744 structure is the only one that is built using brick, the same material used on much of the infrastructure in Schleswig-Holstein (and much of Lübeck). The first crossing  was a pedestrian bridge built in 1644 before it was widened to accommodate horse and buggy and later automobiles. The bridge is located 200 meters south of the Lübeck Cathedral and can be photographed together when travelling by boat. An even closer shot of the church can be made after passing underneath the structure and going 100 meters further. Both are a must

Wall Bridge- Spanning the tributary connecting the Trave and the Stadtgraben carrying Possehlstrasse near the Wipperbrücke, this closed spandrel arch bridge was built in the 1920s but was widened to accommodate traffic. It serves as a connecting point between the Old Town and Possehlbrücke.

Dankwärtsbrücke- Spanning the Trave River at Dankwärtsgrube, the Dankwärtsbrücke is one of three pedestrian bridges spanning this river in Lübeck’s Old Town. It holds the title of being the only wooden bridge in the city, and one that has a lot of charm and is still being visited by thousands of people each day. The crossing is the second one in use and follows the original construction of the bridge built 200 years earlier but was replaced in 2004 due to structural issues.

Professor’s Bridge- Located between Dankwärtsbrücke and Holstentor, the pedestrian bridge was the work of Peterson and Pörksen, architects whose office is located in Lübeck and neighboring Hamburg. Built in 2007 as part of the plan to convert the Trave into a tourist boating port, the concrete bridge features a beam span supported by V-shaped piers which creates a trapezoidal shape with the point in the center of the bridge. This is important to allow boats to pass. The churches can be seen by this bridge.

Holstentorbrücke- Despite its length of 30 meters and being a single span closed spandrel concrete arch bridge, this bridge is perhaps the oldest that ever existed, located at the world renowned Holstentor Gate, the most used landmark of the city in terms of marzipan, paintings, souvenirs and the like. The bridge was first mentioned in 1216 when it was built as a wooden bridge. It was destroyed by flooding in 1320, and between that time and 1516, the bridge was rebuilt three times, with the third crossing being a stone arch bridge. The next bridge resembled the Rialto Bridge in Venice and lasted over 300 years before it was replaced in 1853 by a short span crossing that accomodated both rail and horse-traffic. While the rail line, originally connecting Lübeck Railway station and the harbor was discontinued in the early 1930s, vehicles continued using the bridge, hence the widening of the structure in 1934 to its current shape and form.

Beckerbrücke- Spanning the Untertrave, the pedestrian bridge connects the Lübeck Convention Center with the Beckergrube and provides a direct link to the center of the Old Town with its churches and shopping area. A person needs only seven minutes between St. Jacob’s Church and the Convention Center. The bridge was built in 2004 and features a beam span supported by a set of two-column piers.

Drehbrücke (Swing Bridge)Spanning the Untertrave at Willy-Brandt Allee between St. Lorenz and the Old Town, the bridge is one of only a couple swing bridges left in Schleswig-Holstein that is in operation. The bridge features a curved Howe pony truss, where there are three trusses, the center one of which separates two lanes of traffic. Built in 1892, it is the third oldest bridge left in operation and features a swing mechanism where a combination of rollers and hydraulics are used to swing the bridge open at a 60° angle, allowing ships and boats to pass through the crossing. A video shows the bridge closing after the boats pass through (click here).  Originally used for rail traffic connecting the train station and the harbor ports to the north via Hub Bridges, the bridge was converted to vehicular use in the 1980s and has operated for 121 years with little repairs done on it. The bridge is located next to a famous fish restaurant where a person can dine on some of the city’s specialties with a glass of wine and watch the ships pass through  as the bridge swings open and close.  The bridge is located next to another railroad bridge approximately 200 meters away. The Warren pony truss span with riveted connections spans part of the harbor and can be seen from the train station. It has been sitting abandoned for over a decade, awaiting reuse.

Eric Warburg Bridge- Losing the Herrenbrücke was a blow that the City of Lübeck did not want. Fortunately, the Eric Warburg Bridge was built at the time the 1964 two-span drawbridge was being demolished because of the tunnel. Yet this bridge had been in the planning phases for over a century, starting off with the plan by Peter Rehder to build it closer to the Old Town along the Lübeck-Elbe Canal. Yet the plan was tabled due to opposition from the citizens, as well as the two World Wars. Yet in 2004, the need to establish the connection between the Old Town and St. Gertrud justified the need for a single-leaf draw bridge, which took four years to build. The bridge features a blue-colored steel beam bridge with a center span that opens at regular intervals, controlled by the grey shaped control tower. A video shows you how the bridge works (click here).  Since the Herrenbrücke was removed in 2008, the bridge is the last crossing over the Trave before emptying into the Baltic Sea 10 kilometers to the north at Travemünde.

The bridge also has a history involving a prominent citizen. Eric Warburg, a banker from Hamburg, was of Jewish origin and contributed a great deal to saving many lives during World War II. After emigrating to the US in 1938, he served the American army and helped many people escape the tyranny of Adolf Hitler and his killing machine aimed at exterminating the Jews before and during the war. After Lübeck was heavily damaged during air raidson 29 March, 1942, in which 20% of the historic Old Town was destroyed, Warburg knew of the plan for another series of air raids that would eventually destroy the rest of the city and informed his cousin Carl Jacob Burckhardt, president of the International Red Cross about it. Together, the city was declared a neutral zone and a port where humanitarian aide would enter Germany. The plan was successful and not only was Lübeck spared, but it  was declared neutral governed by the Red Cross until the end of the war in 1945. For his work as well as his engagement in German-American relations, the Emil Warburg Prize was introduced in 1988 and given to people who performed great deeds for keeping the German-American relations sound. Among those receiving the prize were Richard von Weizsäcker (German president from 1984 to 1994), Henry Kissinger (Secretary of State under Richard Nixon) and former US President George HW Bush.

And as icing on the cake…

Puppenbrücke (EN: Bridge of Statues):

The last bridge on this tour is a must-see if you are a pontist or love history. The Bridge of Statues spans the Stadtgraben providing the lone important link between Holstentor and the Old Town to the east and Lübeck’s Railway Station and Bus Depot to the west. The bridge’s history dates back to the 1700s, when the bridge was built using wood. Yet the stone arch bridge was first constructed in 1773 and widened to accomodate traffic in 1907. The bridge features eight different sandstone sculptures on the railings, which includes the statue of the Woman of Peace, which is the answer to the question posed in an earlier article (click here). Each statue represents either a god or a different symbol, which was described further in detail by René and Peter van der Grodt and can be viewed here. These statues were made by Dietrich Jürgen Boy and P.H. Gnekow in 1774 and had been in place until 1985 when they were replaced by replicas and the originals were taken to the St. Anna’s Museum where they can be seen today but under protection from pollution. The bridge also features four different seals called reliefs, each located on one corner of the spandrel of the bridge, representing Earth, Wind, Fire and Water. Those can be seen from boat or by climbing down to the shoreline of the Stadtgraben.

After touring through the Old Town and visiting each of the bridges mentioned here, which will take a day to complete when walking by foot and a couple hours by boat, one should not forget to try the marzipan products, including the marzipan pie provided by the family owned but world renowned Niederegger candy and restaurant, while at the same time, listen about the history of another bridge that used to exist in the city but a tunnel had taken its place. A book was written about this bridge and its history and in the second part on the series, we will have a look at the rise and fall of the Herrenbrücke, located north of Lübeck in the village of Siems, once an industrial port but now a faded memory.

 

Pella Bascule Bridge

Photo taken in August 2013

While in Marion County, going 10 miles east from the abandoned Hwy. 14 Bridge at Red Rock Lake, one should take some time and visit Pella. With a population of 10,400 inhabitants and a small private college, there are many things that make the city proud. The city is home to Pella faucets, windows and doors. It has the largest windmill in the western Hemisphere with the Vermeer Mill. And given the architecture in the city center, Pella prides itself on its Dutch heritage, as it was founded by Dutch immigrants in 1847.

And when it comes to Dutch architecture, one has to include a double-leaf bascule bridge, right? Like its European cousin, Friedrichstadt, Germany, a Dutch community without a bascule bridge just isn’t Dutch. This has to do with the popularity of these bridges in the country, with a huge concentration of them to be found in the country’s capital, Amsterdam. And while the mayor of Friedrichstadt got his wish with the Blue Bridge, built in the 1990s but functions as an ornament- a gateway to the town- this bridge (in the picture) serves as one of the jewels of the architecture one can see while in Pella.

Located in front of the Hotel Amsterdam between Main and First Streets, this double-leaf bascule bridge has been around for only a short time, spanning a man-made canal. This white-colored bridge does not appear to function as a bascule bridge but as a fixed span with pedestrians using the structure on a daily basis. The bridge is decorated with lighting and flowers, making it an attractive place to visit and even photograph. Yet there is no further information as to when the bridge was built or what the motives were behind this bridge. Was this part of a bigger project, or did the Dutchmen miss their beloved structure so much that they needed a replica to add to the heritage?

This leads to the questions of the origin of the bridge and the Dutch’s obsession towards a bascule bridge. Specifically:

1. When was this bridge built? Was it part of a project to reconstruct the city center?

2. Why are Dutchmen so obsessed with bascule bridges in a community outside the Netherlands? Could the bridge in Pella be one of those bridges that fall into the category?

3. Is the bridge used for a festival or for some other function? Or is it just a ornament to cross, a symbol of the town’s city center?

Put your comments down here or in the Chronicles’ facebook page, together with that of the social network pages dealing with History and Marion County and share your thoughts and facts about this bridge.  More photos of the Pella bascule bridge can be found here.

Many of us indentify ourselves based on a piece of heritage we cannot leave behind when emigrating to a new country. For the Dutch, it’s the architecture and in particular, their double leaves. It makes the author wonder what piece of heritage we cannot live without when moving to another place…. Any thoughts on that in addition to the questions already posted above?

 

 

Answers to the Park Complex Questions

214480-L
Photo taken in August 2011

After a brief absence due to other column items to cover and to allow people to be curious about the park, here are the answers to the Quiz provided in a post a couple weeks ago on the FW Kent Park in Tiffin (west of Iowa City) and the rooftop truss bridge. Before mentioning about the bridges and F.W. Kent Park in the quiz, some interesting facts you need to know include the fact that the park was named after two well-known people. The first was Frederick Kent, a photographer who took pictures of life on and off the campus of the University of Iowa, located in Iowa City, for over 4 decades, including his role as the college’s professional photographer between 1915 and his retirement in 1962. He was an avid birdwatcher and published a book on this topic in 1975. Plus he was a walking encyclopedia on Johnson County, which earned him many local and state accolades. He died in 1984 at the age of 90.  The other person was Ron Dunlap, who was a member of the Johnson County Conservation Board from 1970 until his unexpected death in 2010, and spearheaded efforts to restore the bridge brought into FW Kent Park during the 1980s and 90s, with the last bridge being imported in 2003. The Dunlap trail, which crosses all seven restored historic bridges, was named in his honor.

Keeping these facts in mind, here are the answers to the bridge quiz, however, there are many questions that are left open which will be answered through interviews with people who worked with these two gentlemen and posted later in the Chronicles. But in the meantime, here are some facts that will make you curious to know more about the park and the bridges….. 🙂

1. The FW Kent Park is younger than the Historic Bridge Park near Kalmazoo, Michigan. True or False? 

False. The FW Kent Park has been in existence since the 1960s with the name being carried since 1967, honoring Frederick Kent, who was a locally renowned photographer for the Iowa City region. The bridges did not come until the 1990s, with the last one being installed in 2003. The bridges at the park in Michigan were in place between 1996 and 2006, with more scheduled to be imported. Note: The Historic Bridge Park in Michigan is located just southwest of Battle Creek, home of the Kellogg’s cereal company.

2. Which of the following truss bridge types can NOT be found at FW Kent Park?

a. Pratt        b. Warren        c. Whipple     d. Queenpost

Whipple truss bridges are nowhere to be seen at the park.

 

3. The origin of the Rooftop truss bridge was a building that was demolished in Iowa City. Can you name the building and when it existed?

The trusses came from a car dealership in Iowa City that had existed from the 1930s until the building was dismantled. Yet the name of the dealership is unknown.

4. How many bridges can be found at FW Kent Park?

a. 8   b. 10   c. 11  d. 13  e. 15

Eight bridges can be found in the park. Of which, seven are historic bridges that were restored, while the eighth one, a Warren pony truss, is a new bridge built of wood, connected with steel plates. In terms of truss designs, apart from the new Warren pony truss span, the park features two Pratts (one through and one half-hip pony), one V-shaped Pratt pony truss, two Queenpost pony trusses, one bowstring arch and the rooftop truss span.

5. At least one bridge was airlifted to the Park. True or False?

True. One bridge, a through truss span, was airlifted by helicopter to the park in 2003 and placed on new abutments, but not before retrofitting the bridge’s width.

6. All of the bridges brought in were the ones that served traffic in Johnson County.  True or False?

True. All seven historic bridges were crossings over small creeks, including Old Man’s, Deer, Dirty Face and Eagle. Sadly no bridges came from the Iowa River, which slices the county into two, let alone the Cedar River, where the Sutliff Bridge east of Solon is located.

7. How was the Rooftop truss bridge assembled?

After finding the trusses in a road ditch outside Iowa City, workers tried successfully to refit the trusses so that they support the roadway as railings. Additional exterior truss bracings were added to keep the bridge intact. In other words, the roadway is a bridge supported by trusses.

 

8. What activities can you do at the park, apart from photographing bridges?

a. swimming   b. hiking   c. fishing   d. biking   e. all of the above

In addition, you can do some bird and insect watching as many species of birds as well as butterflies and dragonflies can be found in the park. Also one can find some turtles and other wild animals at the park, but beware! Hunting is not allowed.
