Draschwitz Brücke

draschwitz1

Location: White Elster River in the village of Draschwitz, 7 kilometers north of Zeitz in the state of Saxony-Anhalt

Built: 1891-2; Damaged during World War II in 1945, Rebuilt in 1946, Restored in 1999/2000

Type: Parker Pony Truss with subdivisions

Length:  ca. 30 meters

Status: Open to traffic on a weight limit of 6 tons

During a recent bike tour along the White Elster from Gera to Leipzig (all 90 kilometers of it), I came across this unique structure. After passing through Zeitz and having revisited some of its historic bridges (see link), one would expect to see more of these historic bridges along the river, especially as Saxony-Anhalt has a wide selection of historic bridges worth visiting. One needs to see the towns of Halle (Saale), Magdeburg, Quedlinburg or even the bridges in the Saale-Unstrut River corridor in order to gather the impression that the bridges are being cared for by the state; this includes using funding provided by the European Union but also by the federal government to restore them to their original form while ensuring that cars and bikes can use the bridge.

The Draschwitz Bridge is one of these structures that received this kind of care, as it was restored in 1999/2000, which included new wood decking plus paint on the superstructure, as well as work on the foundations. Given its location on a less used road that is occupied mainly by cyclists and locals driving their cars across, the restoration was worth it, as the bridge serves a local road and the White Elster bike trail, which connects Hof (Bavaria) and Halle (Saale), running parallel to the river until its confluence with the Saale River, between Halle and Leipzig.

But what makes this bridge unique is its unusual truss design. The bridge was built using welded connections instead of pinned connections, as seen on truss bridges in general. Welded truss bridges, together with those with riveted connections were starting to come onto the scene at the time of its construction, as vehicular traffic- namely trains, but also later cars and trucks- had increased since the expansion of the railroad. This prompted the introduction of a network of roads connecting towns on the local level, but later expanded to cities on the regional and in the end national levels. While pinned-connected truss bridges were able to handle light traffic on local roads, as traffic increased and highway systems were introduced, they were replaced with truss bridges with riveted connections. Welded truss bridges were introduced in the 1890s to replace the pinned-connected bridges for despite its biggest asset of dismantling and reassembling the bridge at a different location, missing or broken bolts and cracked eye-bars made it difficult to impossible to relocate the bridge. With welded truss bridges, one has the advantage of relocating the bridge without having to take it apart. Plus with the beams fixed together and welded with bolts, there is more resistance to weight that is on the bridge. The Draschwitz Bridge has this on not only the trusses themselves, but also the outriggers that support the two center panels- an anomaly given the fact that truss bridges usually have outriggers on every vertical beam and panel, especially those in the US built after 1900.

draschwitz10

Another unusual feature is the upper chord itself. Normal truss bridges have upper chords that are of either squared shaped beams, V or X-laced or those whose shape resembles the letters I, L and C. They are supported by vertical and diagonal beams that are up to half its size and width. For this bridge, the upper chord and the vertical and diagonal beams are of nearly the same size. However, even more unique is the angled bracings that weave along the top chord, the points sticking outwards by up to 10 centimeters. While some truss bridges in the US and Germany built prior to 1885 may have had features like this bridge, the Draschwitz Bridge is the only known bridge to have an upper chord, decorated with such unusual bracing.

draschwitz8

Apart from the renovations, nothing has altered the bridge, even when villagers installed a plaque on the western wingwall, indicating the high water mark set by the flooding in 1954. Chances are, the White Elster may have been rechanneled after that, raising the bridge to prevent it from being swept down stream. Yet, a curved beam connecting that wingwall and the pier raised some eye brows as we don’t know what this serves, except to support the bridge in one way or another.

draschwitz12

The Draschwitz Bridge is really a gem in the field when it comes to finding historic bridges. The structure continues to serve local traffic and the Elster bike trail to this day. It’s one of the landmarks one should see when passing through Zeitz and the Elsterau, also the last one to see as one bikes north toward Leipzig, but one that the quiet village of Draschwitz should take pride in, one that Saxony-Anhalt has taken great care of, just like the state’s other historic bridges, and one that historians, pontists, engineers should study further to find out more on its history and structural features. It’s the one bridge that a person can spend lots of hours with the camera and a picnic blanket, sitting and indulging at its beauty, surrounded by a historic and natural landscape.

Mystery Bridge Nr. 79: How to Reconvert a Truss Bridge- Going from Deck to Through Truss in Oklahoma

Our 79th Mystery Bridge takes us to Oklahoma; specifically to Whitesboro in LeFlore County and this bridge. Spanning the Kiamichi River at Township Rd. 4044C south of Whitesboro, this bridge is one of the most unusual through truss bridges a person will ever see in the United States. According to the data from Bridgehunter.com, the total length of the bridge was 270 feet with the largest span being 127 feet, the width of the bridge is around 13-14 feet and the vertical clearance is 13.3 feet. Yet despite the date of construction being ca. 1940, this bridge is unusual as it is a pinned connected through truss, thus bucking the standards of truss bridge construction. As many resources have indicated, most truss bridges built at this time had riveted or welded connections, making the structure sturdier and able to carry heavier loads. Pinned connections had a tendency of dislocating or even having the bolts connecting the beams to break off, causing bridge failure. This resulted in many of the structures being taken off the state highway system and relocated onto less-used township roads beginning in the 1920s and extending well into the 1950s, especially as the US was lacking materials and engineers as a result of World War II. Judging by the appearance of the bridge, it appears to have been built between 1910 and 1915 as this was the cut-off period for constructing truss bridges with pinned connections. It was congruent to the time standardized bridges were approved by the state governments, which included not just focusing on truss bridges with riveted connections and either Howe lattice or lettered portal bracings (namely, A, X, M and West Virginia framed), but also the key truss designs, which were the Pratt, Parker, K-truss, Warren, Polygonal Warren and in some cases, Pennsylvania petit.

15970772_1025414347564515_191691455_n

The Whitesboro Bridge features a Warren through truss, but looking at the structure further, it appeared that in its former life, it was a deck truss bridge that had many spans, totaling at least 500-600 feet. One can see how the overhead bracings were added, which consisted of thin cylindrical steel beams. Furthermore, there is no portal bracing, like other truss bridges, and lastly, when looking at the joint where the upper beam and the diagonal end posts meet, the upper beam appears to have been sawed off.  According to observation by fellow pontist, Mark W. Brown, the piers are 2-3 feet wider on each side and 1-2 feet higher, thus creating a slight slope when entering and crossing the structure. Two theories go along with the piers: either they were installed when the bridge was built or they were reinforced after the bridge sustained structural damage because of flooding.

It is possible that this crossing was the first to have been built as the town expanded because of the baby boomer population. But the expansion did not last as many people moved to bigger cities for job opportunities. As of the 2008 Census, the population of the town incorporated in 1908 and named after one of the founders is only 1298. The hunch is that the highest population of Whitesboro was about 3,400 by 1960.

15942278_1025414394231177_2138288738_n

The Whitesboro Bridge has a design that is not like any unusual designs developed by the engineers at all. It is neither a Pegram nor a Kellogg, now is it a Schaper truss, which you can see in many truss bridges built in Germany and other parts of Europe. This bridge is definitely a repurposed truss bridge, having gone from its previous life as a deck truss spanning one of the state’s greatest rivers, like the Red and the Canadian, to one spanning a smaller river but on whose width justified a through truss span.

15995334_1025414324231184_144781007_n

This leads us to the following questions:

  1. When exactly was this bridge built and was there a previous structure?
  2. Who was the mastermind behind this repurposing project and why did the engineer choose this?
  3. Where did the bridge originate from?
  4. When was this built and who was the bridge builder?
  5. Are there other remnants of that bridge left besides the one at Whitesboro?
  6. What do we know about Whitesboro aside the facts and figures presented in wikipedia?

15978418_1025414367564513_1878881793_n

Got any leads, please share in the comment sections here as well as in the Chronicles’ facebook pages. You can also contact Jason Smith at the Chronicles, using the link here. As this bridge is eligible for the National Register of Historic Places, any information you have or can find will help build a solid case for its nomination, let alone preserving it for future generations. As Oklahoma is losing historic bridges in large quantities in the past 8 years, the time is ripe to preserve what’s left of its culture, especially when it comes to unusual designs like this bridge in Whitesboro.

 

Special thanks to Mark W. Brown for bringing this to the author’s attention and for providing some interesting pics of this bridge.

Mystery Bridge Nr. 78: Turner Truss Bridge in Chemnitz, Germany

imgp3881

In 1920, an American engineer, Claude Allen Porter Turner (CAP) designed two different bridge designs that were supposed to simplify the way bridges are constructed. The first was the Turner Flat Slab, a design where the decking portion of the concrete slab was strengthened, thus eliminating the need of extra piers and it would encourage the spans to be longer than usual. The second is a modified version of the Warren truss, where additional lateral beams are constructed midway through the A-portion of the truss, thus creating an A-frame for each panel. Both of these concepts were practiced on the Liberty Memorial Bridge in Bismarck, North Dakota. Constructed in 1922, the bridge featured three Turner through truss spans of 476 feet each, plus the Turner flat slab approach spans totalling 1105 feet- 625 for the west spans and 480 for the east side. It was the only known work for the engineer, whose career started at Gillette-Herzog Manufacturing in Minneapolis in 1900 but then started his own business after declining an offer to relocate to Chicago. The product of the American Bridge and  Foundation Bridge Companies remained in service until its replacement in 2008. It was believed to have been the only one of its kind built…..

…..that is until this recently discovery in Chemnitz, Germany!

Located just two kilometers south of Chemnitz Central Railway Station along the Dresden-Hof-Nuremberg Magistrate at Bernhardstrasse, this pony truss span resembles the same Turner design as the Liberty, but with two unique differences: 1. The truss span is pony and 2. The endposts are vertical. Like the Liberty, the connections are riveted, even in the A-frames of the Warren. Yet some unique features of the truss include the curled cap at the top of the endpost. The end post itself has an I-shape. It is unknown what the length of the bridge is, but it is estimated to be between 60 and 70 meters long. The width is 10 meters between the trusses, the sidewalks on the outer edge is 2-3 meters, thus totaling the width of 16 meters. As the East German government built or imported truss bridges during its 40 years existence, whose designs were mainly Warren (and many modified versions of it) and had not much design to it, it is likely that this bridge was constructed during the 1920s, maybe the 1930s, and survived the bombings of Chemnitz during World War II. 90% of the city center was destroyed by 1945 and 70% of the houses and buildings, dating back to the 1800s were either in shambles or badly damaged. This bridge may have survived the bombing unscathed. Yet the lack of scars from the war might lead to a dispute over the bridge. It may have been rebuilt using replacement parts, but most likely in the late 1940s to encourage passage over the magistrate. If that was the case, then the bridge was built before the Soviets gained full control of its militarized zone, which became the German Democratic Republic (a.k.a. East Germany), while Chemnitz was renamed Karl-Marx-Stadt, a name that remained on the maps until German Reunification in 1990.

With this in mind, let’s look at the following questions to be solved regarding this bridge:

  1. When was this bridge built?
  2. Who designed the structure? Did this engineer use the Turner design or was it just simple coincidence?
  3. Lastly, if this bridge is considered a Turner truss, are there other designs of its caliber that exist? If so, where?

What do you know of this bridge, let alone the Turner truss? Share your thoughts either on facebook page or by using this contact form.  A tour guide on the bridges in Chemnitz is in the making and if there is enough information, this bridge will be added. Let’s see if we can solve this mystery surrounding this bridge, shall we?

Best of luck and looking forward to the findings. 🙂

Mystery Bridge Nr. 77: A Bridge Shaped Like a Shoe

Photos taken in December 2016

Our first Mystery Bridge of 2017 takes us back to Saxony in eastern Germany, and in particular, this bridge. This unusual structure spans the Chemnitz River at Hauboldstrasse, roughly 100 meters south of the Müllerstrasse Bridge in the northern part of Chemnitz. This was discovered while bridgehunting and visiting the Christmas market this past Christmas and is considered one of the most unusual bridges I’ve seen so far.

The bridge features a rigid Luten arch span, but the piers are engraved into the abutments, The east end appears to have the characteristics of a concrete arch bridge, yet the west end has piers that eventually curve to go vertically into the water, like a timeglass. Such piers can be found with the new I-35W Bridge in Minneapolis, when it was constructed in 2009. The bridge’s length is about 70 meters with a width of only five meters, barely wide enough for car to cross. More unusual is the thickness of the concrete and Art Greco design on the top railings. Most concrete bridges built today depend less on concrete and more on steel for supports making them slender in design, but also safer for cars, pedestrians and cyclists to cross. Engineers went out of their way to carve some unusual artwork with this bridge, using as much concrete as possible- even for its third unusual feature, the portal.  The portal itself can be found only on the east side overlooking the city center. It has a hexagonal design that is halved, resembling either a basketball high-top or high heels turned upside down, pending on how you look at it.

The bridge is open to pedestrian and bike traffic connecting an industrial area to the west with the neighborhood to the east. Unusual about this setting is there is not much of both, for much of the former is to the north. One needs to follow the smokestack of the regional power company and take about 15 minutes to get there. The latter still has scars from World War II for much of that area has open lots where houses once stood before the war, creating an empty eerie scene while biking towards the city center. Those that are still standing have been renovated to make it liveable and more accessible for handicaps, while having reintroduced vintage lanterns either of sodium or gas-powered. It is possible that the bridge may have been built in the 1990s to provide access to the neighborhood and make it more accessible and attractive. On the other hand, having the Müller Strasse Bridge to the north, with four lanes of cars, plus additional lanes for bikes and pedestrians, it is possible that the pedestrian bridge was built much further back- between 1930 and 1960, which was later supplanted by the current crossing, but was left in place, as people used it more often as it is part of the local bike trail.  Given the wear and tear of the structure, my hunches are that it was a product of the East German bygone era that has survived the test of time to date.

Smokestack of the Regional Power Company located north of the bridge.

But what do the locals think about this bridge? When was it built? Which engineer dated a woman with high heels and was inspired by her to build this bridge? What else do we know about the bridge’s history? Use the contact form and feel free to add some information in German as well as in English. As we know more about the bridge, it will be added to the tour guide that is being put together on Chemnitz’s bridges, a project that just started a few weeks ago and will continue during the first quarter of the year. Let’s see why the bridge is like it is, shall we?

Sodium-powered vintage lantern

Chemnitz is also home of the iron viaduct, which I wrote about back in 2015. The bridge is still standing despite attempts by the German Railways to push through with demolishing and replacing the 1884 structure with a modern one to accomodate InterCity trains. More on the article here. Details and updates on the bridge’s situation will follow.

2016 Ammann Awards Results

MacArthur Bridge: Winner of the Best Photo Award. Photo taken by Roamin Rich

Record voter turnout for the Awards. Saxony, Route 66,  and Elvis Bridges in Kansas dominating the categories. Eric Delony and John Marvig honored for Lifetime Achievement.

Since 2011 the Bridgehunter’s Chronicles has been hosting the Othmar H. Ammann Awards for historic bridges, focusing on successful efforts in preserving them as well as places with a wide array of historic bridges to see as a pontist, tourist, photographer, historian/teacher or a simple passer-by. In its sixth year of the awards, we saw records getting smashed for the most number of votes, let alone the lead changes that came about in some categories, complete blow-outs in others, thus making this race the most exciting and nail-biting in history. No matter which category you were watching, you probably saw your favorite going from worst to first in as many votes as in the category Best Photo, which saw votes in the thousands, plus a voting arms race among three candidates. We also saw some deadlocks for Tour Guide International, Lifetime Achievement (for second place) and Mystery Bridge, which got people wondering what characteristics led to the votes, because they must have been this good. For some that lucked out, the Author’s Choice Awards were given as consolation, which will be mentioned here as well.

So without further ado, let’s have a look at the results, each of whom has a brief summary:

BEST PHOTO:

This category was the most exciting and nerve-racking as we saw a battle for first place take place among three candidates:

The MacArthur Bridge in St. Louis (Taken by Roamin Rich), Bull Creek Bridge in Kansas (Taken by Nick Schmiedeler) and the Paradiesbrücke in Zwickau, Germany (Taken by Michael Droste).

Despite Zwickau’s early lead in the polls and regaining the lead for a couple days a week ago, MacArthur Bridge won the voting arms race with 38.5% of the votes, outlasting Bull Creek, which received 28.2%. Paradiesbrücke got only 16%.  Devil’s Elbow Bridge in Missouri received 4.2% with fifth place going to the same person who photographed the Paradiesbrücke but in the daytime (2.2%). The remaining results can be seen here.  For the next three months, the winner of the Best Photo Award will have his photos displayed on the Chronicle’s areavoices website (here) and the Chronicles’ facebook page (here), second place winner will have his photo on the Chronicles’ facebook group page (here), and the third place winner on the Chronicles’ twitter page (here). All three will also be in the Chronicles’ wordpress page (here), rotating in gallery format in the header.

Röhrensteg in Zwickau (Saxony), Germany

TOUR GUIDE INTERNATIONAL:

This category was perhaps the most watched by readers and pontists on both sides of the Atlantic Ocean, as four cities were vying for first and third place, respectively before another city decided to crash the party within a matter of only 24 hours before the polls closed, effectively deciding the winner and third place winners. Coincidence or a plot, that remains to be seen. It is known that these five bridge cities will receive further honorable mentions in the near future. The winner of this tight race was Zwickau (Saxony), Germany, which after battling with Calgary during the competition, edged the largest city in Alberta and fifth largest in Canada by a margin of 25.1% to 24%. The reason behind that was the city’s selection of the most unique bridges, one of which, the Röhrensteg, had received the Author’s Choice Award for Best Historic Bridge Finding. There is also the aforementioned Paradiesbrücke, the Zellstoff Truss Bridge and the Schedewitz Bridge, all along the Mulde River and a stone arch viaduct near the train station. The city is worth a treat.

Third place winner goes to Canal Bridges in Brugges, Belgium, which went from seventh place to its final spot in less than 24 hours, knocking the River Tyne Bridges in Great Britain and the Bridges in Glauchau (Saxony) to fourth and fifth places. Brugges had 13.5% of the votes, followed by The River Tyne with 12.6% and Glauchau with 10.5%. Glauchau also received the Author’s Choice Award for its historic bridge find because of its many arch bridges that don’t span the Mulde, like in neighboring Zwickau, but along the railroad line and along the high road leading to the two castles located on the hill overlooking the river valley.

TOUR GUIDE USA:

Unlike in the international competition, this category proved to be no competition at all, for the Bridges of Tompkins County, New York, laden with various types of bridges dating back 150 years, including two iron truss bridges, a covered bridge and some arch bridges, left the competition in the dust. Even at the beginning of the race, it garnered an average of 92% of the votes. In the end, the county won an astounding 89.3%. The closest second place winner was the Bridges in Washington County, Maryland, which had 3.2% of the votes, edging the third place winner, The Bridges of Boone County, Iowa with 2.9%. Having lost the Wagon Wheel Bridge in December to demolition and removal after years of neglect, the Marsh rainbow arch bridges and Kate Shelley’s Viaduct could not compensate of the loss and therefore, people looked to its winner as their bridges are still in used, most of them after having been restored.

BEST KEPT SECRET FOR A US BRIDGE:

Some bridges deserved to immersed in water and covered in coral, used for habitat for underwater life. Others deserved to be immersed and later exposed when the weather extremities are at their worst. The Colebrook Lake Bridge in Connecticut is one that definitely is in the second category. When Colebrook Lake was made in 1969, this Warren pony truss span with riveted connections  became part of the lake bottom and a distant memory among local residents and historians. Its existence came as a surprise, thanks to a severe drought that lowered the lake to its pre-made stage and exposed this structure. Now residents and historians are finding more information on this structure while looking at ways to either reuse it or leave it for nature. Colebrook won the award in this category with 57.4% of the votes.  Second place went to the Marais de Cygnes Bridge in Kansas, one of the rarest Parker through truss bridges in the state, with 22.8% of the votes. Clark’s Creek Bridge, one of many Elvis bridges discovered by Nick Schmiedeler this past year, finished third with 15.4%, yet it was the winner in another category! More on that later. The remaining finishers had an average of 1.5% of the votes, which were a lot given the number of voters having gone to the polls.

BEST KEPT SECRET FOR AN INTERNATIONAL BRIDGE:

Australia’s historic bridges are ones that are worth traveling to visit, for many of them were built by European immigrants with ties to the bridge building and steel industries in their homeland. Only a handful were built locally. The winner and second place winners in this category come not only from the Land Down Under, but also in the state of New South Wales, which is the most populated of the states. The Prince Alfred Bridge, a nearly 150-year old wooden trestle bridge, won the race with 31.4% of the votes. This was followed by another bridge in the state, the Bowenfels Railroad Viaduct, which received 15.9% and the Ribblehead Railroad Viaduct at Yorkshire Dales in Great Britain, which got 8.7%. Tied for fourth place with 7.7% were the Isabella Bridge in Puerto Rico and the Sinking Bridge in Corinth, Greece. And sixth place finisher was the Abteibrücke in Berlin, Germany, with 6.5%, edging its inner-state competitor Röhrensteg in Zwickau and the world’s smallest drawbridge in Sanford, Nova Scotia (Canada) with 6.2% of the votes.

BEST EXAMPLE OF A RESTORED HISTORIC BRIDGE:

In this category, we looked at historic bridges that were preserved for reuse after being considered redundant for the highways due to age, functional and structural deficiencies and cost of maintenance. Like in Tour Guide USA, this competition was very lopsided for a covered bridge far outgained the metal truss bridges and arch bridges in the competition. The Beaverkill Covered Bridge, built in 1865 and located in the Catskills in New York, received a full makeover, using state-of-the art technology to strengthen existing bridge parts and replacing some with those of the exact shape and size. This bridge received 62.4% of the votes. Second place finisher was the Green Bridge (a.k.a. Jackson Street and Fifth Avenue Bridge in Des Moines, Iowa. The three-span Pratt through truss bridge, built in 1898 by George E. King, received its second makeover in 20+ years in order for it to continue serving a bike trail network serving Iowa’s state capital. It received 7.1% of the votes and would have soundly won the competition had one subtracted Beaverkill’s success. Third place finisher was the former Bird Creek Bridges along Route 66 in Oklahoma. The multiple-span K-truss bridges were relocated to Molly’s Landing on one side of the highway, Roger’s Landing on the opposite end, each serving as exhibits and entrances for light traffic. Bird Creek received 6.5% of the votes. Bottoming out the top six are Wolf Road Bridge near Cleveland, Ohio with 4.2%, the County Park Bridge in Hamilton County, Indiana with 3% and Houck Iron Bridge in Putnam County, Indiana with 2.4%.

MYSTERY BRIDGE- USA:

For this category, we’re looking at bridges that are unique but missing information that would potentially make them historically significant and therefore, ripe for many accolades. Although the votes were made into one category, the winners have been divided up into those in the US and the structures outside the country.  For the US, the top six finishers originated from Iowa, with the top two finishers originating from Lyon County.  The Bonnie Doon Bridge, located along a former railroad bearing her name between Doon and Rock Rapids, won the division with 19.8% of the total votes. Not far behind is the Beloit Bridge near Canton, South Dakota, which received 13.2%. Third Place goes to a now extant Thacher through truss bridge in Everly in Clay County, which received 7.7%, 0.6% more than its fourth place finisher, the Kiwanis Railroad Bridge in Rock Valley in Sioux County.  Fifth place goes to the Pontiac Lane Bridge in Harrison County, with 6.1% of the votes. Yet latest developments in the form of photos is almost bringing the Whipple through truss bridge to a close. More later. In sixth place, we have a concrete arch viaduct built by H.E. Dudley near Richmond in Washington County, with 5.5% of the votes. According to John Marvig, that case was recently brought to a close as the now extant bridge was replaced with a steel girder viaduct in 1947.

Camelback arch bridge in Altenburg

MYSTERY BRIDGE- INTERNATIONAL:

All of our entries for the international aspect of mystery bridges were from Germany, specifically, the states of Thuringia, Saxony, Saxony-Anhalt and Brandenburg.  Our first place finisher goes to the concrete camelback pony arch bridge near Altenburg. That structure was built between 1900 and 1920 and still retains its original form. Second place goes to the railroad viaduct in Grosskorbetha, located near Bad Durremberg in Saxony-Anhalt. The 1910 arch structure used to serve a local road to Wengelsdorf, but was removed in November this year, as the German Railways plan to modernize the Y-point where the raillines split to Leipzig and Halle from the south.  The Railway Station Bridge in Halle finished in third, followed by an unusual wire truss bridge in Potsdam and finally, the truss bridge at Schkopau Station, south of Halle.

BRIDGE OF THE YEAR:

The category Bridge of the Year goes out to bridges that made waves in the headlines because of (successful) attempts of restoring them, as well as interesting findings. Our top six finishers in this year’s category consists of those by Julie Bowers and crew at BACH Steel, Elvis Bridge finder Nick Schmiedeler and those along Route 66. Clark’s Creek Bridge in Kansas came out the winner with 53.4% of the votes. This bridge was discovered by Schmiedeler and was one of the first bridges that were dubbed Elvis Bridges, meaning these bridges had been abandoned and hidden under vegetation for many decades. Clark’s Creek is a King Bridge product having been built in 1876.  Second place finisher is the Springfield Bowstring Arch Bridge with 18.1% of the vote. Thanks to Julie’s efforts, this 1870s structure is expected to be restored, relocated to a park and reused after years sitting abandoned, leaning to one side.  Third place finisher is the Times Beach Bridge spanning the Meramec River along Route 66 west of St. Louis, with 6.9% of the votes. This bridge was a subject of fundraising efforts to be restored as part of the Route 66 State Park Complex and bike trail. The bridge was recently given a reprieve from demolition by Missouri Dept. of Transportation. More later.  Rounding off the top six include Gasconade Bridge along Route 66 with 5.4%, Hayden Bridge in Oregon, another project by BACH, with 4.9% and Fehmarn Bridge in Germany with 3.2%. Word has gotten out that the sixth place finisher will receive a rehabilitation job, which will prolong its life by 30 years and keep its symbol as the icon of Fehmarn Island.

LIFETIME ACHIEVEMENT:

Our last category for the 2016 Ammann Awards is for Lifetime Achievement. Unlike this year, there are two winners for this prize, one emeritus and one who is the youngest to win the awards. Eric Delony, who spearheaded efforts in preserving historic bridges through a nationwide program and was director of HABS-HAER for 32 years, received the Lifetime Achievement Emeritus Award. More on his work can be seen hereJohn Marvig became the youngest pontist to win the Lifetime Achievement thanks to his efforts in identifying, photographing and working with authorities in preserving railroad bridges in the northern part of the US. Since having his website in 2010, his focus went from railroad bridges in Minnesota and Iowa to as many as 9 states. The freshman at Iowa State University received 49.3% of the votes, outfoxing the second place finishers, Royce and Bobette Haley as well as Nick Schmiedeler. Christopher Marston finished fourth with 5.4% of the votes, which was followed by Ian Heigh (4%), Kaitlin O’shea (3.5%) and BACH Steel (2.9%).

FAZIT:

And with that comes the closing of one of the most intensive competitions involving historic bridges in the history of the Ammann Awards. It was one that got everyone excited from start to finish, and for many bridges, there is a ray of hope in their future as more and more officials and the communities have become interested in preserving what is left of their history for the younger generations to enjoy. For some profiled that have a questionable future, not to worry. If one person refuses to preserve, another one will step up in his place, just like the electors in the US elections. The interest in historic bridges is there and growing. And that will continue with no interruptions of any kind.

The full results of the Ammann Award results can be found in the Chronicles’ wordpress page by clicking here. Note there are two parts just like the ballots themselves. The links to the pages are also there for you to click on.

This is the last entry carrying the Jacob slogan. Since September 2016 the Chronicles has been carrying the slogan in memory of Jacob Wetterling, an 11-year old boy who was kidnapped on 22 October, 1989 and subsequentially murdered. His remains were discovered in September 2016 bringing a 27-year old case to a close. The murderer has since been sentenced to 20 years in prison with a lifetime incarceration in a state mental hospital to follow. His house was demolished on Christmas Day. As the murder happened closer to home (the author originates from Minnesota), the Chronicles started its Ammann Awards nominations early and carried this unique slogan in his memory. To his parents and friends, he will be remembered as a boy with dreams that never came true, yet he came home to rest and now is the time to bridge the gaps among friends, family and acquaintences, while keeping in mind, dreams can come true only if we let them, and help them along the way to fulfilling them with success and respect.

From the next entry on, the Chronicles will be carrying its present slogan, which is an upgrade from its last one. Some changes will be coming to the Chronicles, which includes establishing a Hall of Fame for the bridges nominated for the Ammann Awards as well as other interesting parts that will be added. Stay tuned, while at the same time, have a look at some mystery bridges that are in the pipelines and are on the way. 🙂

BEST KEPT SECRET TOUR GUIDE:

US:

The Bridges of Boone County, Iowa– Minus the now removed Wagon Wheel Bridge, this county is rich with history involving its bridges, one of which involved a hero who averted a potential disaster in Kate Shelley.

The Crossings along the Chesapeake-Ohio Canal– Built in 1828, the canal system serves four states and provides water to Washington. It also features some of the oldest arch bridges in the country, some of which have been restored since 2005.

The Arch Bridges of Cowley County, Kansas– Until this year, 17 arch bridges served the county, most of which were built between 1890 and 1920 and made of stone. One of the bridges succumbed to flooding this spring.

The Bridges of Cincinnati/ Covington– Several bridges, big and small, old and young can be found in this metropolis, including John Roebling’s suspension bridge built in 1869, one year before his death on the Brooklyn Bridge.

The Bridges of Washington County, Maryland– 22 historic stone arch structures span Conococheague Creek and Antietam Creek, and its tributaries, including Wilson’s Bridge, a 210-foot long bridge built in 1819. Most of the structures are almost 200-years old.

The Bridges of Tompkins County, New York– Over two dozen bridges are found in this county that are historically significant, including their centerpiece, the Newfield Covered Bridge.

International:

Glauchau (Saxony)– Several arch bridges span the Mulde as well as on the hill leading to the castles. As a bonus, a covered bridge and an iron bridge can be found here.

Zwickau (Saxony) – It is extremely rare for a town to have a 500-year old covered bridge with a very unusual design, a cantilever pony truss bridge and an unusual through truss bridge in a community, but Zwickau has that and more.

The Canal Bridges of Brugges (Belgium)– several stone arch bridges span the canals serving this historic community.

Calgary, Alberta– Two dozen bridges, modern and historic serve this Canadian community including those on the city’s historic registry.

The River Tyne- Flowing through Newcastle and Gateshead, this river features 22 improtant bridges as it flows into the North Sea from the eastern UK.

The Bridges of Newark on Trent– Like Glauchau, Newark has 27,000 inhabitants and a wide-array of well-known bridges- ten of them.

The Bridges of Dublin, Ireland– Many bridges from different periods of time can be found here. This includes a pair of cable-stayed bridges, three arch bridges and a couple truss bridges.

The Bridges of Bertram, Iowa (USA)

Rosedale Bridge. Photo taken in September 2010

 

 

Located only five kilometers (two miles) east of Cedar Rapids in the state of Iowa is the village of Bertram. There is not much of the village apart from a cluster of houses along the Cedar River, as well as Big, Indian and Squaw Creeks. But the village of 300 residents living in the largest incorporated area east of Iowa has one special gift for photographers and pontists alike: the area has a lot of pre-1920 historic bridges. Five truss bridges that are over a century old and several arch bridges flank the region, making a photo tour look like a day trip; especially when some of them were built by the likes of J.E. Jayne and Wrought Iron Bridge. Many of them still serve traffic today despite attempts to replace them with more modern crossings. And there is a reason why residents don’t want them: with new bridges comes more traffic and more pollution. Furthermore, they are emotionally attached to the structures as they fit a very natural landscape, which makes the region southeast of the second largest city in Iowa a treat to see.

This tour guide takes you through Bertram and the vicinity, providing you with a glimpse of the bridges you will see when passing through the area. The Ely Street Bridge is being replaced at the time of this revamp of the guide produced in 2014 as the structure was destroyed in a flood.  Blaine’s Crossing is featured as a mystery bridge in this article, which gives us eight bridges featured in this guide that comes with a map. Without further ado…….:

 

Rosedale Bridge:

Spanning Indian Creek on Rosedale Road, just north of Indian Creek Park, this bridge is one of the shortest through truss bridges in the state, with a span of 89 feet. The markings of the pin-connected Pratt through truss bridge- in particular, the Town Lattice portal bracings with knee braces, “fish tail” style floor beams, and sway bracings with riveted angles- are similar to the ones at Ely Street, resulting in the conclusion that the bridge may have been built by J.E. Jayne and Sons of Iowa City. The contractor was the county’s main bridge builder in the 1890s, although only a couple examples remain in use today. 1890 was the date of construction for this bridge, even though it has not been fully confirmed. The bridge was renovated in the early 2000s, which included a paint job shoring up the rip rap and abutments, as well as the replacement of the wood decking and bridge railings (with the typically modern Armco ones), thus continuing its function as a through traffic crossing, albeit only for light vehicles.

Ely Street Bridge:

Located east of Cedar Rapids and accessible from highways 151 and 13, the town of 300 inhabitants is located on a key railroad line between Clinton and Cedar Rapids. The quiet community prides itself in having four historic bridges located within a six-mile radius, all of them located along Big Creek, one of the tributaries that eventually empties into the Cedar River.  The Ely Street Bridge, located on East Bertram Road just south of the railroad crossing is one of them.

Built in 1891, the two-span Pratt through truss bridge, with Town lattice portal bracings and pinned connections, is a key example of a bridge built by J.E. Jayne and Son Bridge Company in Iowa City, located 30 miles south of Cedar Rapids. Born in 1838,  John E. Jayne moved to Johnson County at the age of two where he settled down with his family on a plot of land in Graham Twp., according to county records. He started his bridge building business in Iowa City in the 1870s, with his company located on Gilbert Street. Many bridges built in Linn County were credited to his name, including three in and around Bertram. The red-colored Ely Street Bridge is the best known product built by Jayne, as the structure consists of two truss spans totalling 224 feet long and 14 feet wide. Plaques are found at the top center part of the portal bracings. The bridge is well-hidden but one will cross it right after crossing the railroad tracks.

That is, it used to…

Heavy rainfall caused Big Creek to flood its banks, resulting in trees and other debris falling into the rushing waters. One of the larger trees knocked the two-span structure into the water on June 30th, 2014, cutting the truss bridges into pieces and the street off from its main access to US 151 and IA 13. State and local governments contemplated on what to do with the structure, ranging from rebuilding the bridge in its usual form to a full replacement. The decision in June 2016 to scrap the remaining bridge and replace it with a 300 foot concrete bridge put the last nails into the coffin in the life of a bridge, whose builder has a place in the history books of Linn County, as well as the state of Iowa. Moreover, its design and service on America’s roads serve as a reminder of how truss bridges played a role in paving more roads in the history of America’s infrastructure. The replacement span is expected to open by the end of 2017.

Bertram Road Bridge:

This through truss bridge at Bertram Road is the second to last vehicular crossing over Indian Creek before it empties into the Cedar River. Yet although the blue-colored bridge has markings typical of a bridge built by the Wrought Iron Bridge Company of Canton, Ohio- namely the Town Lattice portal bracings with ornamental features and builder’s plaque in the middle and a plaque with the date of construction found at each end of the portal bracing where the end posts and top chords meet, the 1876 bridge, whose main span is 115 feet long out of the total length of 192 feet, features a rather unique truss design. According to records from the Iowa DOT, the bridge is a double-intersecting Pratt truss bridge, yet one can look at it closer and argue that it is a Whipple truss with features resembling a Pratt truss bridge. The reasons are that the diagonal beams that cross two panels, going directly through the vertical posts, yet there are some that only cover one bridge panel but in a format similar to a Pratt truss.  The design can be discussed similar to the question of a beverage being half-full or half empty.  In either case, the bridge is listed on the National Register, like the Ely Street and Rosedale Bridges, because of its affiliation with one of the largest bridge builders that existed between 1870 and its integration into the American Bridge Company consortium with 27 other bridge builders in 1901, in addition to its unique but debatable design that is perhaps the last of its kind left in Iowa.

Big Creek Bridge:

Spanning Big Creek, the 100-foot long, red-colored Pratt through truss bridge can be seen either from Bertram Street or Holmann’s Road, providing a picturesque view of the structure and its wooden surroundings, year round. The bridge features pinned connections, V-laced bracings supported by riveted-connected angle supports, Town Lattice portal bracings with angle heel supports, and “fish tail” floor beams. Assumptions indicate a work of J.E. Jayne and Sons built in 1890, yet there is no real confirmation of the exact date. Yet records indicate that it was built in 1929, the date that is considered impossible because of the introduction of standardized truss bridges with riveted connections and letter-style portal bracings (such as the A, WV and M-frame style). Henceforth it must be the date of its relocation. Question is where was it originally built?  Like the Rosedale Bridge, the Big Creek Bridge was renovated recently with new paint, new flooring and new Armco railings, yet it functions as a key crossing within the city limits of Bertram.

UP Big Creek Bridge:

Northeast of the Ely Street Bridge is the two-span pony truss bridge with riveted connections. Although it can be seen from Bertram Street enroute to the Big Creek Bridge to the north, it is almost impossible to photograph it from a distance, and given the private property surrounding it, one cannot get close to it to find out the building date and detailed features. One can assume that it was built around 1901-2 to accommodate the increase in rail traffic. The two-tracked Union Pacific line, connects Cedar Rapids with Chicago to the east and Omaha to the west. It is the same line that has the Kate Shelley High Bridge, located 150 miles west of this crossing near Boone.

UP Stone Arch Bridge:

This bridge is the shortest of the crossings in and around Bertram. Built in 1901 as part of the double-tracking project along the now Union Pacific rail line between Cedar Rapids and Chicago, the stone arch bridge is no more than 45 feet long and 15 feet deep, spanning an unknown tributary that empties into Indian Creek. The bridge can be seen from Bertram Road, two miles west of Highways 151 and 13.

Squaw Creek Bridge:

The last bridge on this tour may not be the most spectacular-looking crossing, yet it is one that warrants some more research. The bridge is a concrete slab, measuring between 90 and 120 feet long, 15 feet wide and up to 20 feet deep. Yet given its derelict state, it appears that the structure was built between 1900 and 1920, serving the Chicago and Northwestern Railroad line between Cedar Rapids and Central City, 20 miles to the north. It is unknown when the line was abandoned, yet given the amount of overgrowth and the concrete deck deteriorating, it has been out of use for at least 30 years. As there are no plans for a possible rail-to-trail project, it seems most likely that the bridge will give into nature and sit abandoned until it collapses on its own, but not before some research is done on the crossing.

Blaine’s Crossing

The Blaine’s Crossing Bridge spans Big Creek between Highways 151 and 13 and Bertram. The Pratt through truss bridge can be seen clearly from the main highway, as the crossings are only 600 feet apart from each other and viewing the bridge from a distance, it appears to be a tall bridge- roughly 18 feet in height from the top chord to the river bed. Despite seeing the bridge from that distance, access to the structure is almost impossible unless either negotiating with property owners or having a camera with a lens that can enable a person to take close-up photos from a distance.  During my visit in 2011, I chose the second variant, taking some pictures from a nearby gravel road (Cedar Woods Road), thus finding out the bridge type, the portal bracing and whether the connections are pinned or riveted. Judging by the photos taken (which can be seen here), the bridge is a pinned connected Pratt, with A-frame portal and strut bracing, and has seven panels.  Dave King, another bridge photographer took the first option of getting up close to the bridge (but probably not before talking to the nearby home owners about it first) and looking at the details of the bridge during the winter months (his photos can be seen here as well). There, one can take some assumptions about the bridge’s dimensions. As the truss bridge has seven panels, it is between 120 and 140 feet long with a 15-17 foot width, this not including the fact that the original bridge decking has long since been removed. Also noteworthy is the eye-loop connections of the vertical beam at the outermost panels, which is a rare feature for a truss bridge. The bridge originally served a local road going to Bertram until 1965, when the crossing was supplanted by the Highway 151 Bridge, as part of the project to bypass Cedar Rapids and Marion. Whether or not the road was once part of 151 is unclear, but a mystery bridge article shows the potential of the theory to be true.

A map of the bridges show where they are located so that in case you wish to visit them, you can.
