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.

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.

The Bridges Along the Baltic-North Sea Canal Part III: The Alt Eider Canal

This is a throwback article dating back to April 2011, when the author toured the bridges along the Grand Canal. Going in the opposite direction enroute to Kiel, this part focuses on the remnants of the Alt Eider Canal, which originally snaked its way across Schleswig-Holstein from Kiel to Tönning via Rendsburg and Friedrichstadt. While the western segment was converted into a river when the Baltic-North Sea Canal was built between 1890 and 1895, the eastern segment, running from Rendsburg to Kiel, was abandoned and as a consequence, many areas have become nothing more but ponds and small creeks with locks that no longer are in use. Using a map for this tour guide, here are some of the relicts worth visiting while on tour. 🙂

After an hour of lunch, combined with a trek combing up along the west end of the Kieler Fjorde, passing the university and the state parliamentary building along the way, I ended up in the northernmost suburb of Holtenau, the starting point of the Grand Canal. Measuring about 95 km long and approximately 60 meters wide in many areas, it resembled the Panama Canal, which slices through the isthmus connecting North and South America. The only difference between the two is the landscape, which the Grand Canal goes through mostly flat land. Before the trip to Kiel to start on the journey, I bought a magazine bearing the name “Nord-Ostsee-Kanal” 2011 version from a book store in Flensburg and while staying at the hotel on the city’s east end of Mürwik, I learned about the canal’s history, let alone the origins, and decided to make a parallel bike tour  where I could find and photograph the bridges along both canals, although I would risk not getting from Kiel to Heide before sundown. While my prediction did come true, there was no regret doing what I did, for I would not have had the chance to share my experiences travelling along the Alte Eider and the Grand Canals at the same time.


The Alte Eider Canal had a width of about 30 meters and was 4 meters deep in many areas. While its starting point was in Kiel Holtenau, its path represented a long snake slithering quietly through the flat lands, as the canal made a lot of really sharp turns. Since many ships passing through the canal at the time of its completion had no engines (they would come in 1830s), most of them were pulled by horse and manpower to avoid any collisions with the banks. The canal swerved through many small present-day villages with many locks along the way. They include the villages of Knoop,  Pojensdorf, Rathmannsdorf and Schinkel northeast of the present-day canal and Kluvensiek, Bovenau, and Klein Königsförde located to the south and west of the Grand Canal close to Rendsburg.  And with each village, there were series of locks- more than that of the canal today in its entire length- many of whom are all but relicts today, where people can come and see what they looked like when the Alte Eider had its heyday.
Each canal lock consisted of a bridge, built using a bascule design which permitted traffic to horse and buggy and ships when necessary. There are many different types of bascule (or draw) bridges that were created and developed. The Scherzer rolling lift style was used on the Lindaunis Bridge over the Schlei. In Schleswig-Holstein, double leaf bascules were used most often to span narrow canals like the ones that existed along the Alte Eider. Originating from neighboring Holland (today known as The Netherlands), double leaf bascules consist of two half-bridge spans, each of them supported by cables or chains that are anchored by towers located on each end of the canal. For a textbook style, the cables or chains are connected to counterweight, located above each tower, which if lowered by manpower (or in today’s case machine), lifts the half-span to its vertical position to allow the ships to pass through. To lower the half-span, the weight is lifted up and back to its position above the tower, and the roadway is anchored down in a horizontal position, allowing horse and buggy to pass. An example of this bridge can be found in one of the pictures below.  These types are still being used today in Schleswig-Holstein for small crossings including those along the Eider River in the western part of the state. More on that in the second segment.   At least eight different locks had bridges of this type in service before the Alte Eider was made obsolete by the Grand Canal, one located in each village. This included the ones in Rendsburg, Kluvensiek and Klein Königsförde, which is profiled at the end of the column.

When the Grand Canal opened to traffic in 1895, the Alte Eider Canal lost its significance and was subsequentially put out of service. Much of the canal was filled up with silt, while other sections were dismantled and buried with dirt by farmers in an attempt to convert it into farmland. Some of the locks were dismantled with the bridges removed, while others were left as a landmark signaling the canal’s heyday.  One can see some of these landmarks today when trekking along the remains of the Alte Eider Canal. This includes a Toll house in Pojensdorf, which has since been converted to a museum dedicated to the history of this architectural landmark. There is a restaurant in Rathmannsdorf, located in front of the lock, which serves local delicacies. In Schinkel, a mansion-style hotel built in the early 1800s still exists today, despite being privately owned. Mills can be found in places like Kluvensiek and Bovenau. Parts of the Alte Eider were converted to harbor for yachts in Rendsburg. And one can find bridge relicts in Klein Königsförde and Kluvensiek, the former being a replica of the one that existed before the Grand Canal opened, the other partially filled in but has a history of its own, when looking at the tower’s portal bracings.
Of the eight bridges that existed, four have been profiled here, although one of them no longer exists. They are arranged in the order of direction of the canal, from Kiel to Rendsburg, starting with the first bridge at Pojensdorf.

Pojensdorf Bridge:  Spanning the Alte Eider Canal

Spanning the Alte Eider between Knoop and Pojensdorf, this steel stringer bridge may have replaced a lock and bridge that existed when the canal was in service. The bridge serves as the entrance to the village of Pojensdorf. While the bridge represents a typical short-span stringer bridge used on many roads in Germany, if one goes beyond the bridge and enters Pojensdorf, one will appreciate the landscape that was created by the old canal, let alone the Packhaus in Pojensdorf which was converted into a museum devoted explicitely to the history of this unique canal.

Kluvensiek Drawbridge:

This (now former) drawbridge is probably the most ornamental of the bridges that spanned the Alte Eider Canal. The bridge was built in 1849/50 with the portal towers being designed by Carlshütte Iron Works in Rendsburg. Founded by Markus Hartwig Holler in 1827, the iron works company contributed a great deal with the construction of bridges and other forms of infrastructure along both the Alte Eider and the present Baltic-North Sea Canals up until the Grand Canal’s completion in 1895. However, the company’s heyday did not come until the Ahlmann family took over the business in 1909 and Kate Ahlmann took over the business when her husband Julius died in 1931. She had as many as 3000 workers at the iron works company by the 1950s and contributed a great deal to the economic growth in Rendsburg. Shortly before her death in 1963, a museum dedicated to the history of Carlshütte opened with numerous displays of artwork made of iron, which can be seen today. Sadly though, Carlshütte went into decline after her death and despite surviving one bankruptcy in 1974, the second one in 1997 led to the company’s liquidation. Carlshütte was named after Carl von Hessen, who governed Schleswig-Holstein at the time of the company’s founding.

When the canal was made obsolete by the Grand Canal, the lock was filled in with the exception of a small culvert to allow water to pass underneath. This included the bridge itself even though the two towers still remain standing and can be seen from the road heading to Kluvensiek from Bovenau and the Alte Eider bike trail.

Drawbridge at Klein Königsförde:

Coming up on Klein Königsförde, one will see a replica of a piece of history spanning the Alte Eider Canal on the old locks. Originally there was a bridge that was constructed in the mid-1800s using the double-leaf bascule design, and consisting of towers with an arch design. Yet before the Grand Canal was completed in 1895, the bridge was taken down and not replaced for over 100 years. In the early 1980s a replica of this bridge was constructed using mostly wood for the structure and steel chains for tower support as well as lifting the roadway, even though the crossing is in a fixed position. The purpose is to show the tourist what the bridge looked like during the days of the Alte Eider Canal. The bridge received the Europa Nostra award for its artwork in 1989 and is still in use for pedestrians and cyclists only. A park is located next to the structure on the west end to provide an opportunity to rest and view the village, located on the eastern side of the canal.

Rendsburg Drawbridge:

Subtracting the city of Lübeck, located on the border to Schleswig-Holstein and Mecklenburg-Pommerania, if there is a city that can be considered the one with the most number of bridges worth seeing and learning about in Schleswig-Holstein, Rendsburg would be the place to look at. The city can pride itself for its High Bridge (which will be mentioned in the later columns), but it can also pride itself on the history of bridges that spanned both the Alte Eider and Grand Canals. The Rendsburg Drawbridge is one of the bridges that made the city popular. While there were numerous bridges of this type that were built in and around Rendsburg, this one stands out as it served a main road connecting Hamburg and Flensburg. Furthermore it was one of a few built using iron and may be one of the structures built using the iron from its production facility Carlshütte. Sadly, when the new canal was completed in 1895, the bridge lost its importance and was subsequentially removed. The canal eventually was converted into a harbor, which is still in use today for smaller boats entering and exiting the Grand Canal. Interesting enough was the fact that before the canal was made obsolete, an arch bridge took its place for a while but it is unknown when it was built and when it was removed. Also worth noting is the fact that the drawbridge was overshadowed by bigger and longer bridges spanning the longer canal- one for the trains (High Bridge) and one for the road.

After a tour of the bridges along the Alte Eider Canal, the last segment of the revised tour guide series along the Grand Canal will focus on Kiel, its easternmost terminus. Apart from some neat bridges in the city center, there are some to the east of the city along the Schwentine that are worth noting and visiting. The Schwentine also empties into the Baltic Sea through the Kiel Fjorde but opposite the terminus of the Canal.

2015 Ammann Awards: The Author has some bridge stories to tell

Pot4

To start off this new year, there are some good news as well as some bad news. First the bad news: The deadline for entries for the 2015 Ammann Awards has been pushed back again for the last time. This time the 10th of January at 12:00am Central Standard Time (January 11th at 7:00am Central European Time) is the absolute deadline for all entries, including that for Best Photo, Lifetime Achievement and other categories. Reason for the delay is the low number of entries, much of that has to do with the weather disaster of biblical proportions in the United States and Great Britain, which has kept many away from the cameras and forced many to fill sandbags. The the voting process will proceed as planned with the winners being announced at the end of this month.

The good news: The author has enough candidates and stories to justify announcing his choices for 2015- the first to be announced before the actual Ammann Awards presentations but one that should keep the interest in historic bridges running sky high, especially before the main course. In other words, the author is serving his appetizers right now to keep the readers and candidates hungry for more bridge stuff. 😉

So here is our first appetizer: The Biggest Bonehead Story

Photo taken by Tony Dillon

USA:

Truck Destroys Gospel Street Bridge in Paoli, Indiana- Ever since Christmas Day, this story has been the hottest topic in the media, even breaking records of the number of post clicks on the Chronicles. A 23-year-old woman, who claimed to be Amish, drives a 30-ton truck full of drinking water across the 1880 Cleveland Bridge and Iron Company structure that was only able to carry 6 tons. Naturally, the bridge gave in, yet the excuses the driver brought up became more and more incredulable: 1. I just received my driver’s license, 2. I couldn’t turn around or find an alternative so I took the chance, and 3. (Most outrageous): I didn’t know how many pounds equaled six tons.

Yet the question remains, which was more incredulable: The incident or the consequence of the incident: a mere $135 fine for crossing the light-weight bridge, destroying it in the process?

International:

Viaduct Collapses in Sicily- 2015 was not a good year for bridges outside of the USA, for several key (historic) crossings have met their fate or are about to due to human error. A temporary pedestrian bridge in Johannesburg (South Africa) falls onto the motorway crushing two cars. A pedestrian suspension bridge in New Zealand breaks a cable, causing the decking to twist and send hikers into the water.  Fortunately, no casualties. Both incidents happened in October. The highest glass bridge in the world, located in China, is cracking even though the government says it is safe.

But this bridge collapse on the island of Sicily, which happened in January, was a scandal! The Scorciavacche Viaduct near Palermo was completed in December 2014, three months earlier than scheduled, only for it to collapse partially on January 5th, 10 days after its opening! While no one was hurt, the collapse sparked a political outcry as the multi-million Euro bridge was part of the 200 million Euro motorway project, and as a consequence, officials prompted an investigation into the cause of the bridge. The construction company, which claimed that the accident was caused by “substinence,” tried shooting down the accusations, claiming the accident was overexaggerated. Makes the reader wonder if they tried covering up a possible design flaw, combined with human error, which could have caused the collapse. If so, then they have the (now jailed) Captain of the capsized Costa Concordia to thank, for like the ship that has been towed away and scrapped, the bridge met the same fate. Lesson for the wise: More time means better results. Check your work before opening it to others.

 

 

Best Historic Bridge Find:

While the author stayed out of the US for all of 2015 and focused his interesting findings on European soil, other bridge colleagues have found some bridges that had been either considered gone or had never been heard of before. One of these colleagues from Minnesota happened to find one that is still standing! 🙂

 

USA:

Bridge L-1297 in Clearwater County, Minnesota-

According to records by the Minnesota Historical Society, the Schonemann Park Bridge, located south of Luverne in Rock County, is the only example of a Waddell kingpost truss bridge left standing in Minnesota. This 1912 bridge is now on the National Register of Historic Places.

According to the Minnesota Department of Transportation, Bridge L-1297, which spans the Clearwater River near Gronvich in Clearwater, is the OTHER Waddell kingpost pony truss bridge that is still standing. Its markings matches exactly that of its Schonemann counterpart. Although there is no concrete evidence of when it was built and by whom, Pete Wilson, who found it by chance and addressed it to the Chronicles, mentioned that it was likely that it was built between 1905 and 1910 by the Hewett family, which built the bridge at Luverne. In either case, it is alive, standing albeit as a private crossing, and should be considered for the National Register. Does anybody else agree? 🙂

International:

The Bridges of Zeitz, Germany

It is rare to find a cluster of historic bridges that are seldomly mentioned in any history books or bridge inventory. During a bike tour through eastern Thuringia in March, I happened to find a treasure in the hills: A dozen historic bridges within a 10 km radius, half of which are in the city of 29,000 inhabitants, including the ornamental Moritzburg Pavillion Bridge located on the east end of town. Highly recommended the next time you pass through the area. These bridges will be profiled further in the coming year because of their aesthetic and historic value, which makes the town, resembling an East German bygone era, more attractive. Check them out! 🙂

 

Spectacular Disasters:

Flooding and Fires dominated the headlines as Mother Nature was not to kind to the areas affected, thus they were flooded, destroying historic bridges in the path. If there was no flooding, there were dry spells prompting fires that burned down everything touched. While there were several examples of historic bridges destroyed by nature, the author has chosen two that standout the most, namely because they were filmed, plus two runners-up in the international category. Fortunately for the bridge chosen in the US category, there is somewhat of a happy ending.

USA:

Full Throttle Saloon Fire-  Only a few weeks after celebrating the 75th anniversary of the Motorcycle Rally at the World’s largest saloon, the Full Throttle Saloon was destroyed by a massive fire on September 8th. Two of the historic bridges, relocated here to serve as overlook platforms and stages, were damaged by the blaze with the bridge decking being completely burned away. While the saloon was considered a total loss, bar owner Michael Ballard is planning on rebuilding the bar complex and has already lined up concert events including the upcoming Motorcycle Rally in August. More on how you can help rebuild here. Whether the bridges will be part of the plan is unclear, but given the effort to bring in the structure, it is likely that they will be kept and be part of the project as well. More on the project will follow, but things are really looking up for bikers and bridge lovers alike. 🙂

 

International:

300-year old arch bridge washed out by flooding-

While there was a three-way tie for spectacular natural disasters done to the historic bridges on the international front, this concrete arch bridge in Tadcaster in the UK stands out the most. The bridge collapsed on December 29th as floodwaters raged throughout much of the northern part of Great Britain. It was one of dozens of bridges that were either severely damaged or destroyed during the worst flooding on record. The saddest part was not the video on how the bridge fell apart bit by bit, but the bridge was over 300 years old. Demolition and replacement of the bridge is expected to commence at the earliest at the end of this year once the damages are assessed and the clean-up efforts are under way.

Runners-up:

Coach takes a swim under a culvert in Brazil:

Two runners-up in this category also have to do with bridge washouts due to flooding. One of them is this culvert wash-out in Brazil. A video submitted to the French magazine LeMonde shows what can happen if engineers choose a culvert over a replacement bridge, as this coach sank into the raging creek, went through the culvert and swam away! :-O Fortunately all the passengers evacuated prior to the disaster, however, it serves as a warning to all who wish to cut cost by choosing a culvert over a new bridge- you better know what you are getting into, especially after watching the video below.

 

Massive Panic as Bridge is washed out in India-

The other runner-up takes us to the city of Chennai in India, where flash flooding wreaked havoc throughout the city. At this bridge, the pier of a concrete bridge gave way as a large wave cut up the crossing in seconds! Massive panic occurred, as seen in the video seen below:

 

 

Dumbest Reason to destroy a historic bridge:

The final category for this year’s Author’s Choice Award goes to the people whose irrational decision-making triggered the (planned) destruction of historic bridges. This year’s candidates features two familiar names that are on the chopping block unless measures on a private scale are undertaken to stop the wrecking ball. One of the bridges is an iconic landmark that is only 53 years old.

USA:

BB Comer Bridge in Alabama- Three years of efforts to raise awareness to a vintage cantilever bridge went up in smoke on November 14th, when county officials not only rejected the notion for a referendum on saving the BB Comer Bridge in Scotsboro, but also turned down any calls for the matter to be brought up for all time to come. While the organization promoting the preservation of the bridge claimed that the city and Jackson County would not need to pay for the maintenance of the bridge, officials were not sold on the idea of having the bridge become a theme park, which would have been a win-win situation as far as producing funds for the tourism industry is concerned. Instead, behind closed doors, the contract was signed off to convert the 1930 bridge into scrap metal, giving into the value of the commodity. Talk about short-sightedness and wrist slitting there!

International:

Fehmarn Bridge to come down- In an effort to push through the Migratory Freeway through Fehmarn Island and down the throats of opposing residents, the German Railways condemned the world’s first basket weave tied arch bridge, built in 1963 to connect the island with the German state of Schleswig-Holstein. The official reason was too much rust and any rehabilitation would prolong the bridge’s life by only 20 years- highly disputable among the preservationists and civil engineers given the number of concrete examples of rehabilitated bridges lasting 50+ years. Yet many locals believe that the German Railways is pushing for the bridge to be removed in favor of its own railroad crossing that would carry Fernzüge from Hamburg to Copenhagen, eliminating the ferry service between Puttgarten and Rodby in Denmark. The fight however is far from over as the campaign to save the island and its cherished architectural work is being taken to the national level, most likely going as far as Brussles if necessary. In addition, lack of funding and support on the Danish side is delaying the tunnel project, threatening the entire motorway-bridge-tunnel project to derail. If this happens, then the next step is what to do with the Fehmarn Bridge in terms of prolonging its life. The bridge is in the running for Bridge of the Year for the 2015 Ammann Awards for the second year in a row, after finishing a distant second last year.

 

AND NOW THE VOTING PROCESS AND RESULTS OF THE 2015 AMMANN AWARDS, WHICH WILL BEGIN STARTING JANUARY 11th, AS SOON AS THE DEADLINE FOR ALL ENTRIES PASSES. HURRY TO ENTER YOUR PHOTOS, BRIDGES, AND PERSONS DESERVING HONORS BEFORE IT’S TOO LATE!!!!

Mystery Bridge Nr. 50: A small culvert on a big major highway

Photo courtesy of the Jefferson Highway Archives/ Facebook Page

Culvert: a tunnel-like structure that passes underneath the road, providing a channel for water to flow through. Culverts were first used in the early 1910s as a substitute to beam or even (pony) truss bridges as they were cheap to build, they controlled the flow of water- keeping it from eroding the banks, and they were shorter than the short-span crossings. A culvert has an average length of 20-40 feet; the same applies to the width.  And while they are becoming the norm for small stream crossings, county engineers are using multiple spans as a replacement for a simple bridge span, as was seen with the Miller Station Bridge in western Pennsylvania, three years ago. Although the cost-cutting mentality has forced many to resort to this use, the lone setback is when water backs up on higher ground, thus causing flooding and frustration among farmers and property owners.

But this 50th mystery bridge in the series takes us to this culvert, spanning a stream carrying 585th Avenue between Shipley and Cambridge, in Story County, Iowa. Now many readers are probably wondering why this rather simple culvert is being used as an article. There are two key ones:

1. The road, which is now gravel and owned by the county, used to carry the Jefferson Highway, the second oldest highway in the United States. The highway started in Winnepeg, Manitoba (Canada), and after passing through Fargo, Minneapolis, Albert Lea, Des Moines, Kansas City and parts of Oklahoma and Arkansas, terminated in New Orleans. Although created in 1915, the highway was finalized in 1918 and was the primary north-south highway for four decades, before vast portions were replaced by Interstate highways. Many roads that were part of the highway, including this one, are still marked with the historic sign to this day, indicating where the highway once ran. Known as the Palm to Pine Highway because of the different trees one can find on the highway, the Jefferson intersects with the Lincoln Highway at Colo, Iowa, the oldest highway in the country and one that criss-crosses the country from San Francisco to New York via Chicago.

2. This culvert is not like any culvert one sees on the highway. It spans a small judicial ditch, a dug-up stream that channels water alongside and underneath the road.  The culvert is so small that one can barely see it. If it is seen, then one would think that it is a piece of concrete standing in the ditch and causing a nuisance to those mowing the ditches. The culvert is probably no longer than 6 feet in length and no higher than four feet, which is half the average size of a common culvert. Yet given the Art Deco design on the railings, this bridge was built after 1914, when Iowa introduced state standard bridge designs, which bridge builders had to abide by for safety purposes. The question is, who was behind the idea of this culvert? Why this concept when a steel tunnel culvert or a low-water crossing would have sufficed?

This is where you as the reader and/or researcher should find out about this. If you know of any stories behind this culvert, please contact the Bridgehunter’s Chronicles or place your comments accordingly and share them. The more info, the more likely this mystery will be solved. As the Jefferson Highway will turn 100 years old next year, you can share your stories with them as well. The bridge may be very small and somewhat insignificant, but it does have valuable information that is useful as the highway reaches the century mark in 2015.

Author’s Note: Thanks to the Jefferson Highway Organization for allowing the author to use the pic for this article. 

More Jefferson Highway bridges will be featured in the course of 1.5 years in the Chronicles as the highway celebrates its 100th birthday in 2015. If you want to contribute with a bridge or series of bridges, please contact Jason Smith at the Chronicles and information on how to submit will be provided. There are many valuable historic bridges that once served this unique route and should be honored for their service, even if some of them no longer exist. 

Mulberry Creek Bridge near Ford, Kansas

It is not rare that when a person is on vacation, far far away where he is not reachable that he comes home to an urgent message on the answering machine or in your e-mail inbox begging for help. While I was away at the peninsula of Holnis, located northeast of Flensburg northern Schleswig-Holstein, a gentleman provided an SOS to anyone who could help him save a unique bridge from becoming a pile of scrap metal and replaced with an ugly concrete culvert that is a 20th of the length of the original bridge itself. As I had posted about the call for mystery bridges to be solved prior to my departure in the second week of August, it was not surprising that he asked me for his help.
Wayne Keller needs your help. He is currently compiling some information and ways to save the Mulberry Creek Bridge. Located southwest of Ford in Ford County, Kansas (which is  southeast of Dodge City), the bridge features two 85 foot pinned connecting Pratt through truss spans with Howe Lattice portal bracings (9-rhombus with curved heel bracings).

The bridge was built in 1906 by the Kansas City Bridge Company at its original location, Second Avenue in Dodge City. It featured six 85 foot spans over the Arkansas River. In 1935, the bridge was replaced by a concrete span, but the truss spans were relocated to Coronado Road, where it was in service until 1958 when it was replaced by a concrete bridge on a new alignment. Two of the spans were salvaged and relocated to Valley Road, where it has been in place since 1959. The bridge has been susceptible to flooding as it is located near a watershed, which is over 15o square miles. The bridge now serves a general maintenance road and is rarely used. But it becomes a dirt road after passing the Keller Ranch.  Yet if the county commissioners have it their way, the bridge will be history before year’s end. The last inspection in May of this year revealed a broken pin in one of the connections between the diagonal and vertical beams and the bridge was subsequentially closed to all traffic. On 4 June, 2012, the commissioners voted unanimously to tear the bridge down and replace it with a concrete culvert that is seven feet long- an intelligent choice given the fact that the creek is wider than the culvert, and culverts are susceptible to erosion caused by high water, as well as flooding upstream. There was an attempt to sell the bridge to Mr. Keller three years earlier but despite his agreement to the proposal, the deal never bore fruit for unknown reasons.

Mr Keller is looking for some information on the bridge to make it eligible for the National Register but also for ways to keep the bridge in service- and on his property, even if it means fixing the structure to keep it open for private use only. Judging by the information found so far, the bridge has potential to be considered historically significant and repairs on the bridge will prolong its life by up to 50 years, while at the same time, is 70% cheaper than replacing it with a culvert and allow the road to be dammed up, causing flooding upstream and potentially lawsuits by farmers and ranchers affected. More information in the form of oral sources and other articles to help justify the case for saving the bridge is also welcomed.
If you have any information that will be helpful to Mr. Keller in his quest to save the bridge, please contact him at the following e-mail address: maandpakeller@cox.net

Update from Wayne Keller:

The plan of the county engineer is to removed the bridge an sell as scrap
metal and replace with a metal seven foot culvert. The bridge is 170 long
and is about 15 feet above the channel. The proposed culvert will be buried
one foot below the channel and the top of the road will be about 12 feet
below the deck of the current bridge. So the cross sectional area of the
opening for water flow will go from basically a triangle 170 along the top
and 15 of depth or about 1,275 square feet to the opening the culvert 38.5
square feet less maybe a square foot that is buried below the channel.

The bridge is on a general maintenance township road and provides me all
weather access to my residence(our family residence since 1905) and my ranch
and cow calf herd. It is also the mail route. From my driveway going east,
the roads become minimum maintenance township roads and are very nasty due
to eroded roadbeds that now serve as ditches when it is wet. The bridge is
my one and only connection to the outside world in wet weather. During wet
weather access to the other lands, which are only farmlands with no
residences, that are east of my driveway are not accessible except by ATV or
high clearance 4WD vehicles. Therefore, during wet weather, I, my hired hand
and the mail man have to use the bridge, along with emergency services if
needed at my place, and no other landowner can use the bridge for to access
their property because of the minimum maintenance road system past my
driveway.
The Bridgehunter’s Chronicles will keep you informed on the developments with this mystery bridge and would like to thank you for your support.
