There are tourist traps and then there are tourist traps with historic bridges involved. The tour guide provided here clearly belongs to the latter, and it has a story behind it. As we were travelling north on Interstate 75 in the direction of the Mackinac Bridge, we came across a bilboard that directed us to Bridgeport, home of Michigan’s number one historic bridge. I had known about the first bridge on the tour guide prior to the US trip, yet we also learned about Bridgeport’s next door neighbor, Frankenmuth, a typical German community that was full of surprises. We decided to pull off first at Bridgeport and then head over to Frankenmuth and found more surprises than what we learned about. What will a tourist find in the bridges in Bridgeport/Frankenmuth apart from what is highlighted by links and in the Instagram pages will motivate you to spend a couple days in the region that is only 10 miles south of Saginaw.

State Street Bridge (Bridgeport):  When travelling North on Interstate 75, one will come across a bilboard that says Bridgeport, home of Michigan’s number one historic bridge. A first where a bridge is a centerpiece, a tourist attraction, a magnet. However, from a bridgehunter’s point of view, together with his family members who were also armed and dangerous with Lumixes and Pentaxes, the city’s chamber of commerce was right and then some. 🙂  The Bridgeport Bridge spans Cass River at State Street. Built in 1906 by the Joliet Bridge and Iron Company, the bridge features a pin-connected, two-span Pratt through truss bridge with three-rhombus Howe lattice portal bracings with 45° heels. The bridge is a distant cousin of one in Jackson, Minnesota at Petersburg Road, which was built a year later but was removed after flood damage in 1995. The difference is the length of the structure, which is nearly twice as long as the one in Jackson: two 126-foot long truss spans with a total length of 252 feet. Jackson’s was 130 feet, but the total length was 150. After serving vehicular traffic for almost a century years, the bridge was closed to traffic because the center pier was being undermined by the currents, causing the western span to tip over. Yet thanks to efforts conducted by Nathan Holth of historicbridges.org, who documented the Bridge in detail from 2004 to date, the Bridgeport community collaborated with the state and an engineering group, Spicer Group to conduct an in-kind restoration, overseen by Vern Mesler. This was done in 2010 and consisted of dismantling the two trusses off site, sandblasting the bridge parts, and reassemble the bridge exactly as it was built, but with new bolts and eyebars in many cases. The only “new” aspects of the bridge was the new center pier, new abutments, railings and the approaches to the Bridge. That was in addition to a picnic area and pavillion as a bike trail connecting Bridgeport and Frankenmuth was being constructed. The bridge today looks just like it was when it was originally built, including the wooden decking, thus presenting a historic appeal.  Yet there are two more reasons to visit the bridge and pay homage to those who restored it. First of all, there is a historic town park on the eastern bank of the river, where a “revived” main street is lined with historic stores, church and houses dating back a century ago. The Bridgeport Museum, which owns the property, is located along this historic street. Yet it would be a crime to miss out on reason number two, which is the eateries that are located across the Dixie Highway from the bridge, going to the east. The Butter Crust Bakery is located on the corner of Sherman Road and Dixie, and from 6:00 in the morning until 5:00pm on all but Sunday and Monday, one can enjoy jelly-filled donuts, long-johns, mini-cakes and even a glazed ugly (caramel filled pastry with hazelnuts and/or almonds for a very low Price. All of them are locally made and use all natural ingredients- have been doing so for over a half-century. 🙂  An ice cream parlor at State Street just off the highway offers the finest ice cream in the region, including Rocky Road (ice cream with fudge, dark chocolate and marshmallows) and Michigan Pothole (dark chocolate with chips), the latter is named after a typical curse one will find on all Michigan’s roads- potholes, big and small. Both of which are highly recommended, whereas one can see the bridge from the parlor and can even enjoy watching people cross it from the inside.  🙂

 

CSX Bridge

Bridgeport (CSX) Railroad Bridge: To the north of the Bridgeport Bridge at State Street is another through truss bridge that gives the photographer on the State Street crossing a chance to get a few shots. The Bridgeport Railroad Bridge spans the Cass River, carrying the CSX Railroad, located approximately 300 feet away. The bridge is considered the longest of the bridges profiled here in the Bridgeport/Frankenburg area, for even though the main span- a Warren through truss with riveted connections and heel portal bracings- is 130 feet long, if one counts the trestle approaches, especially on the southern end, the total length is 530 feet. The bridge was constructed in 1908-09 by the American Bridge Company in New York. The 1908 date came from the concrete abutment, whereas the truss bridge was brought in a year later; the plaque is on the bridge. Together with the Bridgeport Bridge at State Street, the CSX crossing is one of a handful of bridges that still has a railroad and a road crossing running along side or adjacent of each other, but are trussed. The bridge is basically an accessory to the other one nearby and all its historic places located next to it, that it is basically a win-win situation for bridgehunters and historians alike. One cannot photograph one without getting the other.

Gugel Bridge at Beyer Road: Spanning the Cass River, this unique crossing has had a share of its own history as the 114-year old structure is the oldest surviving bridge in the county. The pin-connected Pratt through truss bridge with Town Lattice portal bracings and a pony truss approach span, was originally built to accommodate the Dixie Highway until 1919. It was then relocated to this site where it served traffic until it was closed down in 1979. 25 years later, William ‘Tiny’ Zehnder led efforts to restore the bridge to reincorporate it into the bike trail connecting Bridgeport and Frankenmuth. There are historic markers and benches at the bridge for people to relax when taking a break, while enjoying the natural surroundings of the Cass.

Frankenmuth Covered Bridge:

In the eyes of fans of iron bridges, this bridge is a modern “Schande” to the City of Frankenmuth. In the eyes of German tourists this bridge is too “Kitschisch” just like with the rest of the predominantly- German community whose resorts and restaurants resemble those in the Alps, even though the origin of Frankenmuth is from the Franconian Region of Bavaria. Yet in the eyes of covered bridge fans and those who have never seen Frankenmuth before, this bridge is considered the crown jewel for the community, competing with the Bridgeport Bridge at State Street for the best historic Bridge in this tour guide.

Yes, the Frankenmuth Covered Bridge, built in 1979 by Milton Graton & Son of Ashland, New Hampshire, is considered historic, even though in ten years time, it could be listed on the National Register of Historic Places because of its unique truss design, its aesthetic features and its association with the community. The bridge is 239 feet long and has an A-Frame gable roofing which covers not only the one-lane road deck but also the pedestrian walkway that is on the outside of the bridge, separated by its Town Lattice truss design. Its gabled attic roofing on the sides make it resemble a covered Bridge in the Swiss  For cyclists going from Zehnder’s Restaurant on the west bank to the Bavarian Inn Lodge on the eastern side it is best to push your bike across on the pedestrian walkway as this covered Bridge sees a lot of traffic on a regular basis. The bridge, which carries a weight Limit of 7 tons, is a backdrop to the scenery on both sides of the river. On the east end, there is the Bavarian Inn and Restaurants which includes a park and many acres of green. On the western end there is the Business district, which includes small shops, restaurants and an open-air stage where polka and Bavarian-style music are played daily.  The bridge is next to the docks where boat tours are available to explore Frankenmuth. The Frankenmuth Covered Bridge has several names, but the most common is Holz Brücke (although the words are together in German), whereas Zehnder’s is also used for the masterminder behind the bridge was the town’s entrepreneur, William “Tiny” Zehnder (1919-2006).  Zehnder was the face of Frankenmuth because of his establishment of the Bavarian Inn in 1959, which was basically an extension of one of the restaurants he had owned prior to that. From that time until his retirement in 2004, Tiny carved a place in the history of Michigan by turning original small-town businesses into that of a Bavarian-style architecture which not only revived the town’s Franconian heritage but also made the community of over 6,500 people a popular attraction. Tiny died in 2006, but his family still runs the Bavarian Inn complex today.

Frankenmuth Pedestrian Bridge  Perhaps the most interesting bridge in Frankenmuth and on this tour guide that is worth mentioning is this pedestrian bridge. The bridge is the newest one on the block and can be seen from both the covered bridge as well as the Highway 83 Bridge leading into downtown. The bridge is a concrete pony girder, using a similar art Greco design and flanked by flags and ornamental street lanterns on both sides. The bridge is estimated to be between 150 and 170 feet Long and about 10-12 feet wide. The first impression was that with a design like that, it was probably 80 years old. Yet with the structure being between 15 and 30 years old, one could conclude that the bridge could serve as an example of fancy pedestrian bridges that can be built if engineers and city leaders would not worry about the costs but more on the Geschmack the community would like to live with. Not everything needs to be made of just a slab of concrete.

Bronner’s (Black) Bridge:  When entering Frankenmuth from the south along Michigan Highway 83, this is the first bridge you will see. Bronner’s was once located over Cass River at Dehmel Road, having been built in 1907 by the Joliet Bridge and Iron Company. The bridge features a Pratt through truss design with A-Frame portals, whose top chord is decorated with curved lower-cased m and n patterns. The bridge has a total length of 180 feet with the main span being 151 feet long. The decking is 16 feet wide and the height clearance is 14 feet. After 75 years in service, the bridge was relocated to this site, over Dead Creek at Grandpa Tiny’s Farm, one of the ideas concocted by William “Tiny” Zehnder because of his years of farming, alongside his role as Frankenmuth’s well-known entrepreneuer. It has been in its place ever since then, yet it is heavily fenced and secured with cameras to ensure no one walks onto the property unless it is open to tourists. However, you can photograph the structure from both the highway as well as the road going past the farm, at Townline Road. The bridge is located only 500 feet from Bronner’s, the largest store in the world that sells Christmas ornaments and lighting. Regardless of which country and the nostalgia, if you are looking for as special ornament or lights, you will find it there. That includes bubble lights, an American past time that is trying to make its comeback yet they are rare to see.

There are more along the Cass River, but this tour guide will hopefully Show you the bridges you can visit while experiencing a mixture of German heritage on the part of Frankenmuth and local heritage on the side of Bridgeport. Being only six miles apart, the bridges are easily accessible, both by car as well as by bike or foot. The evidence can be seen in the map below as well as by clicking onto the highlighted links in the guide. There one will see that the Bridgeport/Frankenmuth Region is Michigan’s number one hot spot for bridges spanning over a century’s worth. It is definitely worth a stop for a few hours before travelling to the Mackinac Bridge and the state’s Upper Peninsula to the north.

Mystery Bridge Nr. 86: Brick Culverts spanning Drainage Canals and Gullies along the North Sea

north sea 3

Culverts- tunnels that channel water under roads. Culverts are used as a substitute for (mainly small to medium-sized) bridges spanning creeks and small waterways as they have several advantages. First and foremost, they provide minimum maintenance, as either earth and roadway cover them or the short crossings are anchored to the ground and supported by abutments. It acts as a canal for directing water under the roadway but also as a dam to keep debris from blocking the roadway. Yet the drawbacks to culverts is that they are not really effective against high water for floodwaters can undermine culverts by washing out the roadways approaching them. In some cases, they can even collapse, swallowing cars in the process, if they attempt to cross them. If they are not washed out by flooding, the high water can cause flooding upstream up until the crossing itself. In summary, engineers should really think about the advantages and disadvantages of culverts before they even implement them as replacements for bridges deemed obsolete.

north sea 1

This mystery bridge deals with a culvert (or should I say a series of culverts) but in order to better understand the logic behind this, we need to look back at the types of culverts that exist and the oldest known culvert known to human kind.  There are five different types of culverts that are used today: pipe, box, pipe arch, arch and bridge slab- the first three can be multiple spans, the last two are single spans of up to 30 meters. All of them are usually built of steel, stone or concrete. Only a handful have been built using brick.

The oldest known culverts that exist in the world go very far back- way back to the Bronze Age. There, you can find Arkadiko Bridge in the state of Argolis in Greece. Built between 1300 and 1190 BC, the stone culvert has a total span of 22 meters and an arch span of 2.5 meters. It is one of four remaining bridges of its kind using an Mycenaean arch design, all of them are located near Arkadiko.

The next one in line is a stone arch bridge over the River Meles in Izmir in Turkey. Built in 850 BC, this bridge is the oldest of its kind still in use. In Australia, the Macquarie Bridge, featuring a double-barrel arch culvert, is considered the oldest bridge still in use. The 1816 bridge can be found in the Royal Botanical Gardens in Sydney. The Old Enon Stone Arch Culvert, built by Samuel Taylor in 1871 and spans Mud Run in Ohio, is the oldest known culvert in the US and one that was built using limestone.

The culverts in the Eiderstedt region in the German state of Schleswig-Holstein may not be as old as the aforementioned bridges, nor is it definitely the oldest in Germany- that honor goes to the Stone Arch Bridge (built in 1146 AD) over the River Danube in Regensburg (Bavaria). But given their appearance, they are one of the oldest in the region, let alone in Schleswig-Holstein. The culverts discovered during my tour along the North Sea to Westerheversand Lighthouse consists of box culverts, built using brick as material. They each span a drainage canal which is used to divert water away from the fields during high tides (German: Flut). And despite the bike trail careening along the dikes that are lined along the shores of the North Sea, these culverts are still in use for farm vehicles. The concept is odd, but because farming is practiced in the Eiderstedt region, brick culverts were used along with concrete and sometimes wooden bridges to haul farm vehicles.

 

The dikes were established in the early 1960s, in response to a massive storm that flooded large parts of western Schleswig-Holstein, Lower Saxony and the City of Hamburg in 1962. 400 people lost their lives in Hamburg alone, as dike failures took them by surprise and almost all of the hanseatic city was under water. With the dikes came the rechanneling of waterways, eliminating natural gullies, as one can see while traveling along the North Sea coast. The damming of the rivers, such as the Eider, Au, Sorge and Treene, caused the massive extinction of marine wildlife, including the sturgeon, which used to lay eggs upstream close to the rivers’ starting point. The last sturgeon was caught in 1969 and there has not been a single sturgeon in the region ever since. The creation of the Eidersperrwerk near St. Peter-Ording put the last nails in the coffin of the natural cycle of the North Sea, protecting farmers and residents from the flooding processes.

Yet the culverts seen in the pics are much older than the dike and drainage systems that have existed since the 1960s. Judging by the green and yellow moss on the brick and the decoloration of the brick and concrete, it is estimated that the culverts are at least a century old, if not older. Unfortunately, there are no records of the date of construction of the culverts, let alone the bridge builder(s) responsible for building them. Not even the German bridge website Brueckenweb.de has any data on the bridges, nor the Dusseldorf-based Structurae.net. Only a map where the author found the structures and the pictures are the only piece of information that is known to exist.

 

While some records may be available through local authorities in Husum, St. Peter-Ording or Eiderstedt, the chances of finding concrete information is very slim, because the culverts are only 20 meters long with a center span of only 5 meters, and there are dozens of them that are known to exist, aside from the ones that were found near Westerhever.

Do you know of some information on the history of these ancient culverts? Let alone the number of culverts that still exist in the region alone? If so, then please contact the Chronicles and share some information about them. Any clues, including photos, will be of great help. The culverts will be included in the book project on the bridges in Schleswig-Holstein. Information on how you can contribute can be found here. (Hinweis auf Deutsch: Sie können die Information in der deutschen Sprachen übersenden, da der Autor sehr gutes deutsche Kenntnisse hat.)

 

The culverts and the covered bridge profiled here, are a couple of many bridges the author found during his trip to the Eiderstedt region. However, there are plenty more that visitors should see while vacationing there. The author has a few bridges that one should see while visiting the Eiderstedt region. The tour guide will come very soon.

 

Author’s notes:  Enclosed is a map with the exact location and specifics of the culverts found during the trip. Information on the Great Flood of 1962 in Hamburg/ Schleswig-Holstein can be found here. A video on the event can be found here.

Ironically, an even bigger flood occurred 16 years later after the dikes and dams were built. It all occurred during the year summer never existed which ended with the Great Blizzard of 1978/79 that crippled the northern half of Germany, stranding thousands of motorists and causing massive flooding in Schleswig-Holstein alone. More information can be found here. and here.

The Bridges of Ulm, Germany

neuentorbr. ulm.jpg

Located along the Danube River, the city of Ulm, with a population of over 123,000 is one of the oldest cities in Germany. First mentioned in 850, the city had straddled the river for almost a millenium, making it one of the key points of trade and commerce. It had once been declared an Imperial City by order of Friedrich Barbarossa in 1181. However, thanks to Napoleon’s conquest in 1805, Ulm was parted along the river, making it part of Baden-Wurttemberg, whereas the settlement east of the Danube was declared Bavarian and renamed Neu-Ulm. The names have remained the same ever since, although both cities are deeply engaged in joint ventures on the public and private scales, and are sister cities of New Ulm in Minnesota (USA). Some of the key characteristics Ulm has to offer include a professional basketball team “ratiopharm Ulm,” The Ulm Minster Cathedral with the world’s highest steeple surrounded by historic buildings and a large market square, the historic city hall, a pyramid-shaped modern public library, one of the largest collection of “Fachwerk” houses dating back to the Medieval Era (many located along the canals streaming through the southern part of the old town, and memorials honoring scientist Albert Einstein as well as Hans and Sophie Scholl, leaders of the White Rose movement that propagandized against the regime of Adolf Hitler.

And then there are the bridges that are worth mentioning. While all of the Danube crossings in Ulm/Neu Ulm were destroyed towards the end of World War II, a large portion of the pre-1945 bridges were spared  destruction and subsequentially repaired to make them functional again. Whether it is the Neutor Bridge or the stone arch bridges along the Blau Canal, or even the rebuilt Herd Bridge, Ulm today still has a wide array of bridges that fit the cityscape, some of which conform to the Renaissance period landscape in a way that a person is actually walking back into time to get a glimpse of Ulm’s past.

This tour takes you to the most noteworthy bridges in Ulm one should visit while visiting the city. The goal is to provide you with a glimpse at the role of the bridges in the city’s development and their survival through two World Wars. While there are over five crossings over the Danube River, the Herd Bridge will be profiled here because of its historic significance despite being rebuilt after World War II. The other bridges were built in the 1960s on and do not have the historic taste in comparison with the bridges mentioned here. For some of the other bridges profiled here, information is missing on their history- in particular, the bridge builder and the year of construction. If  you wish to add some information about these bridges, please contact Jason Smith at the Chronicles, and that information will be added.

A map of the bridges’ and their location are found here and the bridges….

 

Herdbrücke with Neu-Ulm in the backrgound
Herdbrücke with Neu-Ulm in the backrgound

Herdbrücke (EN: Herd Bridge):  

Location: Danube River (main channel) at Donaustrasse (Ulm) and Marienstrasse (Neu Ulm).

Bridge type: Closed spandrel arch bridge with ribbed spandrels

Length: 75 meters

This bridge is one of two crossings that carry a single street over both channels of the Danube River. Ironically, the Gänsetorrücke in Neu Ulm, despite spanning the narrower channel of the river is longer than this bridge by about 21 meters. This bridge features a single span elliptical arch design wide and tall enough to accomodate boat traffic along the river. Built in 1949, its predecessor was a three-span brick arch bridge built in 1832 and named after Ludwig Wilhelm. Unfortunately in an attempt to slow the advancement of American and British troops from the west, the Nazis imploded the bridge in April 1945, a month before Germany capitulated in Berlin and Flensburg, respectively (please click on this link for more information on this topic). A temporary bridge was erected, which remained in service until this bridge was built. Today, this bridge serves as the key link between the city centers of Ulm and Neu Ulm, while at the same time, its historic significance fits in nicely with the surroundings of both cities: a 1949 bridge whose modernity fits the cityscape of Neu Ulm but its arch design fits  nicely with the old town of  Ulm itself. A nice compromise for a crossing like this one.

Neutorbrücke (EN: Neutor Bridge):

Location: Ulm-Treutchingen-Nuremberg Railline at Neutorstrasse NE of Ulm Hauptbahnhof (Railway Station)

Bridge type: Steel cantilever truss bridge with Warren truss features

Built: 1907 by Levi and Büttner as well as Machinefabrik Esslingen

The Neutor Bridge is the most ornamental of the bridges in Ulm. At over 120 meters long, the bridge’s main features are the towers, whose finials are covered with gold egg-like figures. The towers portals features the city’s shield with its black and white color. When taken from Kienlesbergstrasse, you can capture the bridge and the cathedral all in one, as long as the weather is cooperative.

 

While designed by Levi and Büttner, the construction of the  bridge was done by the firm Maschinenbauwerk in Esslingen, a very popular steel fabricator of bridges and train locomotives until the late 1960s. The company was founded by Emil Kessler in 1846 and was solely responsible for the construction of railroad bridges, railroad tracks and train locomotives and coaches. Apart from this bridge, the company was responsible of the building of the Unterreichenbach Railroad Bridge in 1874 (today, the only example of a Schwedler truss bridge left), The Neckar River Steel Arch Bridge at Plochingen in 1949, and The Fehmarn Bridge in 1963. The company survived several takeovers and concourses during its 120+ year history before the company announced its cessation of production in 1966. Shortly thereafter, it was bought by Daimler-Benz.

Despite being used regularly and its thoroughly done maintenance, the bridge will receive another crossing only 200 meters to the west, which will provide a more direct connection between the city center and train station  to the southwest as well as the freeway Highway 10 to the west. While the design has been announced, construction has not started yet as of present. It does appear though that the bridge will be left in place as a secondary crossing going to the northeast once the new crossing is open by 2020.

Location: Munich-Ulm-Stuttgart Railline at Ulm Hauptbahnhof (Railway Station)

Bridge type: Cable-stayed suspension bridge

Built: 2007 replacing the Blaubeurerbrücke

The Ludwig Erhard Bridge is the first bridge you will see when disembarking the train at the railway station. In the daytime, one can see the blue and grey colors of the tower and cables as it decorates the hillside in the background. At night, however, the colors change to yellow, for the towers are lit by sodium street lamps lining up the meridian and the inner portions of the towers, thus making photography an interesting adventure. The bridge replaces the Blaubeurer Bridge, a steel girder bridge from the 1950s that had corroded away thanks to the black smoke from the trains combined with heavy traffic. Yet this combination steel and concrete bridge improves a key link along Karlstrasse between the city center, Neutorbrücke, the railway station and the eastern suburbs on one end, and the freeway Highway 10 and parks to the west. All of the mentioned locations are centralized and easily accessible even by foot.

Bleicher Hag Bridge:

Location: Munich-Ulm-Stuttgart Railline and railroad yard at the junction of Am Bleicher Hag and Blaubeurerstrasse at Ulm-Lehrertal

Bridge type: Bedstead Pratt pony truss with riveted connections

Built: ca. 1920

The Bleicher Hag Bridge is the longest of the bedstead truss bridges that exist along the railroad lines serving Ulm, with five spans of 120 meters, totalling 600 meters. There is little information about the construction date of the bridge, let alone the bridge builder, yet given the popularity of the riveted truss bridges after the turn of the century and the effects of World War I, a date of 1920 best made sense to pinpoint. The caveat with this bridge is its narrowness- only 3 meters wide and with a weight limit of six tons.

But given the increasing demand of rail traffic and the improvement of vehicular traffic, chances are likely that this bridge may be replaced with a larger, more appealing structure in the next 10-15 years. But it depends on the availability of money and manpower to make it happen.

Lehrertal Railroad Overpass:

Location: Railroad line at Y-junction of Ulm-Treuchtingen-Nuremberg Line and Munich-Ulm-Stuttgart Line, north of Ulm Hauptbahnhof.

Bridge type: Bedstead subdivided Warren pony truss bridge with welded connections 

This bridge is hard to find, unless one wishes to walk across the Highway 10 bridge on the north side. Here is where one can get the best photo. The bridge is unique because of its curved spans as it crosses the rail lines going east past Ulm. Most likely this bridge is used for freight traffic not wishing to stop at Ulm Railway Station, located only 500 meters to the south. Like the Bleicher Hag Bridge, the Lehrertal Bridge has little information on its history but it appears that the bridge has been in service for 60+ years, namely because of its welded connections that had started becoming popular at that time. Yet more information is needed to confirm this.

Schiefeshausbrücke:

Location: Grosses Blau Canal on a pedestrian path between Schwörthausgasse and Fischergasse

Bridge type: Brick arch bridge

There are many small crossings along the Blau Canal that compliment the Fachwerk houses in the Old Town. Yet this two-span arch bridge is the more popular of the crossings, and one of the more visible bridges to photograph. The bridge dates back to the 1700s and it is built using brick. No information on its length is given, but it is estimated to be 20 meters long and only three meters wide. The bridge is located only 15 meters behind Das Schiefe Haus, the oldest existing house remaining in Ulm that dates back to the 1500s and one whose name fits the description, as seen in the picture below:

The house is the only one of its kind in Germany with this unusual feature. It is a now a bed and breakfast, located right on the canal. Anybody care to eat or sleep at the water level? 😉

Weinhofbergbrücke
Weinhofbergbrücke

Weinhofbergbrücke:

Location: Grosse Blau Canal at Weinhofbergstrasse and Auf der Insel

Bridge type: Brick arch bridge

Located at the north tip of the island surrounded by the Blau Canal, this bridge is the lesser visible of the brick arch crossings because of the Fachwerkhäuser and vegetation interfering with the view. Nevertheless, the bridge fits nicely in the cityscape, providing access to some of the small shops in the Old Town. It is located behind one of the recently restored Fachwerk houses (the light brown colored one as seen in the picture) where a gallery and private residence occupies it. The bridge dates back to the 1700s but unlike the one at Schiefeshaus, this one carries automobile traffic but at a snail’s pace because of the high number of people soaking in the scenery of Ulm’s Old Town.

There are many more to see in Ulm, but these examples are the ones that should be visited first because of their historic and aesthetic appearance and how they fit the cityscape. Many of them are difficult to find and one will end up walking past them as they see the Fachwerk houses or even the other places of interest in the Old Town. But in case you stop at at least a couple of them to pay homage to them, you will have a chance to learn how oatingthey have played an integral part in the city’s development over the past three centuries. Unlike the ones in New Ulm in the US, where most of the crossings are now modern, these crossings are unique because of their history and design, even more so because of how thy fit Ulm’s cityscape, thus adding them to the storied list of places to see while in Ulm. Taking the line from Hans Scholl, one can sum up Ulm’s history as the following: Es lebe die Geschichte und Kulturerbe, in addition to his famous last words: “Es lebe die Freiheit.”

EN: Long live freedom, history and heritage.

2014 Ammann Awards: The Author Chooses the Best Bridge Stories

Bentonsport Bridge spanning the Des Moines River in Van Buren County, Iowa. Photo taken in December 2014

To start off the Author’s Choice Award version of the 2014 Ammann Awards, presented by the Bridgehunter’s Chronicles, I would like to present you with an overture which is in connection with this year’s theme: Bigger is not always better. Enjoy!

 

This year’s Author’s Choice Awards features some of the most interesting stories of how people have come together to save their valued work. However, we have a story of a bridge found underneath a pub, as well as a failed attempt to salvage a historic bridge, and a disaster caused by gravity. And finally stupidity at its finest- caught on tape and youtubed! So without further ado, here are my pics for 2014:

Most Spectacular Disaster:

USA:

Ledbetter Bridge in Kentucky- Spanning the Tennessee River, this 1931 three-span polygonal Warren through truss bridge was one of the latter works of architectural art built by Polish engineer, Ralph Modjeski (1861-1940). The bridge no longer exists as it was removed last month, several weeks after a replacement span 700 feet downstream opened to traffic, but one cannot help but watch sections of the bridge collapse on its own, as seen in the photo gallery here.  After reporting one of the approach spans dropping by two feet in 24 hours, officials fenced off the entire bridge, only to later watch sections of it fall on the shoreline. Cause: Erosion undermining the piers, plus some vultures perching on the railings of the affected spans, as the photographer stated.

International: 

Cherryvale Bridge in New Brunswick, Canada- Covered bridges have been especially hardest hit this year, as fire, oversized trucks and natural disasters have damaged or destroyed over three dozen bridges in North America and elsewhere. The Cherryvale Bridge in the province of New Brunswick was one of those unfortunate victims, as floodwaters knocked the 1870s wooden structure off its foundations in May, and the structure flowed downstream before being smashed against a concrete bridge carrying a highway. More on this story hereAs beloved as they are, covered bridges are usually rebuilt by demand from residents. This is the case as well, but will it happen with this bridge? We’ll have to see….

 

Best Historic Bridge Find:

USA: 

Rocky Balboa Railroad Bridge in Durham, North Carolina- This railroad underpass, featuring a 100-year old deck plate girder span, may be a typical bridge accomodating rail traffic. But (and the music from Rocky Balboa will support this), it has had a record of annihilating semi trucks and trailers, as well as tractors, busses, and other overweight vehicles. This DESPITE having every form of warning system and sign in place. Here’s a video to prove it:

 

International:

The Parade Bridge in Norwood (South) Australia- Australia has a wide variety of metal, concrete and wooden bridges dating back to the early 1800s. This bridge, located underneath a pub, was found by chance by the owner as the venue was undergoing extensive renovations. Made of parapet and cobblestone and built in the 1850s, this bridge has a unique history, which can be found here.

Honorable mentioned: The Kersten Miles Bridge in Hamburg, Germany- Built in 1897 and named after the mayor of Hamburg during the Medieval times, this arch bridge is one of the darlings of Hamburg one needs to see, if one wants to know which of the 2,500+ bridges should be visited in the second largest city in Germany. Apart from its ornamental appearance and the fact that the bridge is made of brick, a recent discovery of a pflaster mosaic underneath one of the spans is another reason to visit this unique landmark. More on this discovery can be found here.

Best Way to Salvage a Historic Bridge: USA:

San Francisco-Oakland Bay Bridge East Span- The 1936 eastern half, consisting of cantilever truss spans, was replaced with a cable-stayed span with concrete girders last year and is still being dismantled even as we speak. Yet one person is looking at salvaging parts of the bridge for sustainable housing developments. Although it would look unusual to today’s housing standards, as seen in the article here, it would at least preserve the legacy of the eastern half of the bridge, which partially collapsed in the earthquake in 1989.

Also worth mentioning: Devil’s Elbow Bridge in Pukaski County, Missouri- The Freedom Prime Bridge and this bridge were two of the candidates considered for the author’s choice awards. Yet while Freedom received some accoldaes for best preservation example, this 1923 two-span Parker truss bridge got this one for two reasons: 1. The bridge was part of the Mother Road (Route 66) and because of the importance of the crossings along the highway that had once connected Chicago and Los Angeles, efforts are being undertaken to save what is left of this historic highway. 2. The bridge underwent an extensive renovation, which included new decking, sandblasting and repainting the trusses and making the bridge look just like it was when opened 91 years ago. The bridge should set an example for a pair of other crossings that have recently been rendered unsafe and whose futures are in doubt. More here

International: Katzenbuckel Bridge in Ebenhausen, Bavaria (Germany)- Spanning a rail line near Augsburg in Bavaria, this arch bridge was in the way of progress, for the German Railways want to expand the line and electrify it. The solution: Instead of razing the structure because of its historic significance, the plan is to raise the bridge to better accomodate traffic. Impressive but also one that will have other regions with similar bridges to consider this option, for there are enough candidates to go around. More on the plan can be found here.

Worst Example of Restoring/Using a Historic Bridge

USA:  Blue River US 40 Bridge in Kansas City, Missouri- Preservationists and locals are scratching their heads about this 1931 bridge, a steel through arch bridge that is the product of a pair of local bridge builders. The bridge was dismantled to make way for its replacement in August, but in a way that the parts were cut apart and left in a pile, waiting to be taken to its new home in Grandview. Photos of the bridge before and after its dismantling can be found here. Given the “logic” behind this process, the first and foremost question that comes to mind is: How are you going to put the structure back together again without altering its historic integrity? Or are you going to scrap it? My prediction: Its induction into Nathan Holth’s Wall of Shame.

International: Kramer Bridge in Erfurt, Germany- This bridge in the news but in a negative sense. The face of Thuringia’s capital was the focus of a drug operation, used in the German mystery series, Tatort (Scene of the Crime). The episode was aired in December and drew fire from viewers who deemed both the usage and the content to be inappropriate. Shortly after the release, two of the three actors resigned and the German channel MDR decided to scrap the Erfurt series. Lessons on how Tatort should be produced and how places of interest should be used without degrading it should be given by those who have been with the series for over 2 out of the four decades of its existence on German TV, including the likes of Ulike Folkerts, Axel Prahl and Jan Josef Lieffers, who play investigators for their cities (Ludwigshafen and Muenster, respectively.)

 

Biggest Bonehead Story We had a lot of candidates for this category, many of whom just could not learn to shorten the height of and/or lighten the weight of the load. The end result: covered bridges losing their tops and other bridges dropping to the ravine with their load on it. Yet only two examples really standout and should serve as a signal to truck drivers to NOT rely solely on GPS and assumptions, but to obey the traffic signs, or face liabiity.

Pollock’s Mill Bridge in Jefferson, Pennsylvania- Spanning Ten Mile Creek near Jefferson, this single span Whipple through truss bridge, built in 1878 by the Massilon Bridge Company in Ohio is one of the last remaining iron bridges in western Pennsylvania. Yet it almost became a hunk of twisted metal after a tanker truck tried crossing the structure, only to fall partially through the decking. To make matters worse, the driver dumped liquid contents into the stream to lighten the load and keep it from collapsing. A double-environmental catastrophe. Yet with two trucks following him, he should have known better than to first drive through the height restricted underpass located just a half mile before the bridge and then try crossing this bridge, right? Leadership prevents stupid things from happening. Fortunately, the bridge will be repaired and nothing was severely adversed in the water. However, as the article stated here, it could have been worse…..

Watford Bridge in North Dakota- Spanning the Little Missouri River at US Hwy. 85, this Warren through truss with V-laced portal bracings has dealt with a lot in the 55 years in service, especially as it is located near the Bakken Oil Fields. This includes oversized vehicles crossing it and damaging the overhead bracing. Sometimes stupidity is best shown on video, and the truck driver probably did not realized how much of an idiot he was for ignoring the height restrictions until watching the amateur video taken by another truck driver and his passenger, who  spiced it up with some commentary (Note- some comments may not be suitable for children under 13.)

 

This sums up my picks for 2014. As you can see, we had some interesting stories, all caught on photos and film in hopes that drivers pay attention to their load when using the bridges. Because even the most modern bridges can only take so much. Take this advice in mind: Less is Always More, regardless of the gas price.  After watching the videos and reading the articles pertaining to the bridge picks, have a look at the winners of the 2014 Ammann Awards coming up in the next article…..

 

Beaver destroys historic bridge in Bavaria

KUTZENHAUSEN-BUCH/ AUGSBURG- The Rothbrücke, located in the district of Augsburg in the community of Kutzenhausen has been in the news recently because of a rather interesting story that is making residents and Bavarians scratch their heads as to how this could happen. The 40-50 foot long beam bridge with concrete decking that spans a small creek has come under attack from an unlikely source, and it has caused the mayor to pursue measures to demolish and replace the bridge with haste. Beavers have been busy taking the bridge apart, piece by piece, where they have undermined the bridge’s abutments and wingwalls by digging several holes behind it, as well as along the shoreline surrounding it. The abutment supports the decking of the bridge, whereas the wingwalls allows water to flow freely under the bridge and keep the dirt back. The end result of the beaver’s work has been the area having several holes and tunnels at and behind the abutments, making it look like Swiss cheese, according to reports by the newspaper, Augsburger Allgemeine. The problem was first discovered in 2010, resulting in the weight limit of 3.5 tones being imposed on the bridge. But it was not enough for the beavers to widen their tunnel network and bring the bridge to a point of collapse. According to the mayor, Rupert Kugelbrey, the abutments are so undermined that the bridge could collapse at any moment.  While the bridge has been closed off to all traffic including pedestrians since the end of February of this year, plans are now in the making to remove the bridge at the earliest possible convenience for safety reasons. Whether there will be a replacement for the 40+ year old bridge to follow remains open. But it has provided locals and pontists with some humor, as the beaver is being talked about among the social network community. And it is no wonder, for beavers have a potential to bring down trees and dam up streams, causing flooding. That they have the potential to destroy bridges by undermining important parts is something that is going to have engineers look at other ways to keep wild animals from destroying other bridges, regardless of age and materials used.  For this beaver, it will have to find other bridges to undermine, once the Rothbrücke is removed, but not before receiving the Chronicles’ Author’s Choice Awards in the process, which will be presented next year.

Respect. 🙂
