Starting in the Fichtel Mountains in northeastern Bavaria, the River Pegnitz snakes its way through steep cliffs and deep forests enroute to Nuremberg. It’s hard to believe that one could build dozens of bridges and tunnels to accommodate rail traffic. But that was part of the concept for the construction of the Pegnitztal Railway in 1874. Using the section of the Dresden-Hof-Nuremberg Magistral at Schnabelwald as its starting point, the project to build the line took three years to complete, ending in 1877 to provide direct access to Bayreuth from Nuremberg. Originally the Magistral went through Bamberg but railroad officials chose Bayreuth as the quicker alternative. At Schnabelwald, the line branched off to the east, reaching Marktredwitz and ending at Cheb in the Czech Republic by 1879.   As many as 23 railroad bridges and seven tunnels occupy the stretch between Schnabelwald and Hersbruck near Nuremberg. Many of them are of original construction. Two thirds of these bridges are truss spans mainly of Warren design.

Sadly, these bridges are in danger of being demolished and replaced. The German Railways (Deutsche Bahn) is planning to electrify the entire rail line to Nuremberg from Dresden (via Bayreuth and Hof) and Cheb (via Marktredwitz), respectively, to provide better and faster service among the cities. The plan is to have more passenger and freight service running on electricity by 2030, including Inter-City trains. And with that, all the bridges should be replaced.

Or should they? Residents of the communities have voiced their opposition to replacing the bridges due to their historic character, high costs for the concrete structures and the increase in noise in the region. Since 2012, the initiative to save the Pegnitztal Bridges has been in place with the goal of saving as many of the 23 structures as possible. There have been meetings, hiking events and the like since the initiative started and as of date, many people from the area have joined in the fight to protect these bridges and find more constructive ways to restore them and reuse them as part of the modern route.  To determine what these bridges are all about, here’s a tour guide video on the bridges along the Pegnitztal Railroad with close-ups of them all.

The fight to save them have been mixed. Engineering surveys have recommended five of the 23 structures to be rehabilitated and fit for further use. Yet sadly, five of them are scheduled to be replaced. While one of them, a short, 20 meter span, was replaced in 2013, the following three were replaced in 2018, as seen in the video below. Currently, temporary bridges are being built while designs for the new structures are being determined.  It is still unknown what will happen with the remaining 16 structures. But one thing is clear, the Initiative will continue to fight for every bridge until either the renovation or replacement job is completed. The German Railways have recently introduce measures to provide 180 billion Euros for rehabilitatinig bridges over the next ten years and have been able to compromise on some of the bridges. Yet still, they are baby steps in the name of progress, and more will have to be done to ensure a peaceful co-existence between a modern railline going northeast running on electricity and protecting the history of the structures, typical of the Pegnitztal Rail line, historically significant and definitely one that fits in the nature and is worth seeing while traveling along the Pegnitz.

Bridgehunter Awards for Lifetime Legacy Post Humous: John F. Graham

John F Graham
John F. Graham lecturing at the 2010 HB Conference in Pittsburgh. Photo taken in August 2010

When I first met John Graham at the 2nd annual Historic Bridge Conference in Pittsburgh in 2010, my first impression of him was that he was a conservative, dressed up as white collar worker, but a man of detail and experience.  It was John F. Graham who came up with a concept of augmented reality for structural analysis of bridges.

Augmented reality is a computer term that I had recently collected some general information on through a pair of presentations in an English for IT class at the Erfurt University of Applied Sciences in Germany. It basically analyses the inner portion of structures to analyze problems and find solutions. It had been introduced for medicine for identifying tissue damage in humans, making a precise diagnostic and recommendations for improving the body damage where the damage occurred.  Yet could Augmented Reality work for infrastructure, such as bridges?

Apparently according to Graham, it does. In theory based on trial and error combined with experience, Mr. Graham at the conference showed that augmented reality can identify structural deficiencies inside bridge structures, through the use of special sensors, and make recommendations for fixing them. This latest technology would save money and prolong the life of the bridge, especially after the structure is rehabilitated. Evidence in praxis was shown with the Red Jacket Railroad Trestle south of Mankato, Minnesota later that year, for the Minnesota DOT was in charge of rebuilding the trestle after floodwaters undermined one of the piers, forcing officials to remove the deck plate girders while watching the stone pier collapse. In the other piers, structural weaknesses were identified to a point where the piers were reconstructed to resemble the original. The restoration ended in 2011.  Other rehabilitation projects involved this type of technology which saved costs and opened the doors for reusing historic bridges.

Mr. Graham’s presentation based on this concept was one of many aspects that will make him a person who was conservative but reasonable when it came to the decision of rehabilitating bridges that were an asset to the area and replacing those that deteriorated beyond repair. He was a true Pittsburghese, having been born in the Steel City on 2 April, 1936 and studied civil engineering at Carnegie Tech (today known as Carnegie Mellon University. For most of his career, he was Director for Engineering and Construction for Pittsburgh’s Allegheny County, a position he held until 1989. During his time, he was responsible for the rehabilitation of hundreds of bridges in and around Pittsburgh, including the Sister Bridges, Sixteenth Street and the arch bridges at Fort Pitt and Fort Dusquene, just to name a few. He also had to replace some, like at Sutersville and Coraopolis, according to Todd Wilson, a civil engineer who knew him well during his days at Carnegie Mellon. Mr. Graham in 1978 pushed for and supported legislation that would allow the Federal Highway Administration to allocate the 90:10 funding ratio, whereby state and local governments would only bear 10% of the cost for rehabilitating or replacing the bridge, the former Graham championed and led to the prolongation of the lives of several of Pittsburgh’s bridges. Legislation continued this 90:10 ratio and prioritized rehabilitation until the Minneapolis Bridge collapse in 2007, which resulted in more radical measures to replace bridges. To the end, Mr. Graham continued advocating for identifying and fixing deficiencies in the structures, claiming that they were cost effective and would save on the use of materials needed for new bridges. Indirectly, it was a plus when identifying the historic significance of the bridges.

In 1989, Mr. Graham became the Director of Capital Projects for the City of Pittsburgh, where he oversaw the construction of the Pittsburgh International Airport and other related construction projects, including the Southern Beltway. He later worked for the Pennsylvania Turnpike Commission and later taught engineering classes at Carnegie Mellon. He even operated his own civil engineering firm, where he was responsible for several projects, including the infrastructure for Heinz Field, home of the Pittsburgh Steelers American Football team. Much of the work in the greater Pittsburgh area has Mr. Graham’s name on it, and his unique conservative approach to bridge engineering will be remembered, even as people cross several of Pittsburgh’s restored historic bridges, of which he’s left a mark in at least half of them.

John F. Graham died peacefully on 14 March, 2019 with his daughter Wendy and her husband Marc by his side. In the last two years of his life he lived with her and her family in Philadelphia, which included her two sons. He was preceded in death by his wife, Kay.  Mr. Graham was a true Pittsburghese and one who left a mark in Pittsburgh, the US and beyond, especially for his work in the field of civil engineering. Therefore, for his work, the Bridgehunter’s Chronicles is awarding him and his family Lifetime Legacy Post Humus with a big thanks for his contributions. Because of him, we have found many creative ways to make bridges safe and maintain its integrity instead of replacing them outright, a concept that does more than waste money. It impacts the environment negatively because of materials used that are dwindling and non-renewable.

2019 Author’s Choice Awards: Mr. Smith Picks Out His Best Ones

bhc newsflyer new

GLAUCHAU (SAXONY), GERMANY-

With 2019 and the second decade of the third millennium over and done, we’re now going to reflect on the key events in the area of historic bridges and feature some head-shakers, prayers, but also some Oohs and Aahs, jumps of joy and sometimes relief. Since 2011, I’ve presented the Author’s Choice Awards to some of the bridges and bridge stories that deserve at least some recognition from yours truly directly. Some of the bridges from this edition are also candidates in their respective categories for the Bridgehunter Awards.

So without further ado, let’s take a look at the winners of the Author’s Choice Awards in their respective categories starting with the unexpected finds:

 

Best Historic Bridge Find (International): 

2019 was the year of unique bridge finds around the globe, and it was very difficult to determine which bridge should receive the Author’s Choice Prize. Therefore the prize is being shared by two bridges- one in Germany in the state of Saxony and one in Great Britain in the city of Bristol.

img_20190320_181255445

Rosenstein Bridge in Zwickau (Saxony), Germany:

Our first best historic bridge find takes us to the city of Zwickau and an unknown historic bridge that had been sitting abandoned for decades but was discovered in 2019. The Rosenstein Bridge spans a small creek between the suburb of Oberplanitz and the bypass that encircles Zwickau on the west side and connects Werdau with Schneeberg. The bridge is a stone arch design and is around 200 years old. It used to serve a key highway between the Vogtland area to the west and the Ore Mountains (Erzgebirge) to the south and east, transporting minerals and wood along the main road. It later served street traffic until its abandonment. The name Rosenstein comes from the rock that was used for the bridge. The rock changes the color to red and features its rose-shaped design. A perfect gift that is inexpensive but a keeper for your loved one.

Brunel Swivel Bridge in Bristol, UK:

The other bridge that shares this honor is That Other Bridge. Located in Bristol, England, the Swivel Bridge is very hard to find, for the structure is underneath the Plimsol Bridge, both spanning the River Avon. While Bristol is well known for its chain suspension bridge, built over 150 years ago and spans the deep gorge of the Avon, the Swivel Bridge, a cast iron girder swing span,  is the oldest known bridge in the city and one of the oldest swing bridges remaining in the world, for it is 170 years old and one of the first built by I.K. Brunel- the suspension bridge was the last built by the same engineer before his death. Therefore, the Swivel Bridge is known as Brunel’s Other (Significant) Bridge.  The Swivel is currently being renovated.

Best Historic Bridge Find (US/Canada):

Fox Run “S” Bridge in New Concord, Ohio:

“S-Bridges” were one of the oldest bridge types built in the US, featuring multiple spans of stone or concrete arches that are put together in an S-shape. It was good for horse and buggy 200-years ago, especially as many existed along the National Road. They are however not suitable for today’s traffic, which is why there are only a handful left. The Fox Run Bridge in Ohio, as documented by Satolli Glassmeyer of History in Your Backyard, is one of the best examples of only a few of these S-bridges left in the country.

 

Royal Springs Bridge in Kentucky:

The runner-up in this category goes to the oldest and most forgotten bridge in Kentucky, the Royal Springs Bridge. While one may not pay attention to it because of its design, plus it carries a busy federal highway, one may forget the fact that it was built in 1789, which makes it the oldest bridge in the state. It was built when George Washington became president and three years before it even became a state.  That in itself puts it up with the likes of some of Europe’s finest bridges.

Biggest Bonehead Story:

We had just as many bonehead stories as bridge finds this year. But a couple of stories do indeed stand out for these awards. Especially on the international level for they are all but a travesty, to put it mildly.

 

International:

The Pont des Trous before its demolition of the arch spans. Jean-Pol Grandmont (Collection personnelle/Private collection). [CC BY (https://creativecommons.org/licenses/by/2.5)%5D
Tournai Bridge in Belgium: 

Sometimes, bigger is better. Other times less means more. In the case of the senseless demolition of the Pont des Trours (Bridge of Tears) spanning the River Scheldt in Tournai, Belgium for the purpose of widening and deepening the river to allow for ships to sail to the River Sienne from the Atlantic, one has to question the economic impact of using the boat to get to Paris, let alone the cultural impact the demolition had on the historic old town. The bridge was built in 1290 and was the only bridge of its kind in the world. Its replacement span will resemble an McDonald’s M-shape pattern. In this case, less means more. Smaller ships or more trains to ship goods means better for the river (and its historic crossings) as well as the historic city. In short: Less means more.

Link: https://bridgehunterschronicles.wordpress.com/2019/08/17/pont-de-trous-the-bridge-of-tears/

 

Runner-up: Bockau Arch Bridge (Rechenhausbrücke) in Saxony.  

Residents wanted to save the bridge. There was even a group wanting to save the bridge. The politicians and in particular, the Saxony Ministry of Transportation and Commerce (LASUV) didn’t. While the 150-year old stone arch bridge over the Zwickau Mulde near Aue was the largest and oldest standing in western Saxony and was not in the way of its replacement- making it a candidate for a bike and pedestrian crossing, LASUV and the politicians saw it as an eyesore.  While those interested wanted to buy the bridge at 150,000 Euros. Dresden wanted 1.7 million Euros– something even my uncle from Texas, a millionaire himself, would find as a rip-off.  Supporters of the demolition are lucky that the bridge is not in Texas, for they would’ve faced a hefty legal battle that would’ve gone to the conservative-laden Supreme Court. The bridge would’ve been left as is. But it’s Saxony and many are scratching their heads as to why the demo against the will of the people- without even putting it to a referendum- happened in the first place. As a former member of the Friends of the Rechenhausbrücke, I’m still shaking my head and asking “Why?”

USA/Canada:

The “Truck-Eating” Bridge at Gregson Street before its raise to 12′-4″ in October 2019 Washuotaku [CC BY-SA (https://creativecommons.org/licenses/by-sa/4.0)%5D
Gregson Street Overpass in Durham, NC:

This story brings out the true meaning of “Half-ass”. The Gregon Street Overpass, which carries the Norfolk and Southern Railroad (NSR) is an 80-year old stringer bridge that has a rather unique characteristic: Its vertical clearance is 11 feet 8 inches (3.56 meters).  It’s notorious for ripping off truck trailers, driven by truck drivers who either didn’t see the restriction signs, traffic lights and other barriers or were unwilling to heed to the restrictions because of their dependency on their GPS device (Navi) or their simple ignorance.  In October 2019, NSR wanted to raise the bridge to 12 feet 4 inches (3.76 meters) to reduce the collisions. The standard height of underpasses since 1973 have been 14 feet (4.3 meters). End result: the collisions have NOT decreased.  Epic fail on all counts!

My suggestion to NSR and the NCDOT: If you don’t want your bridge to be a truck-eater, like with some other bridges that exist in the US, like in Davenport and Northhampton, make the area an at-grade crossing. You will do yourselves and the truck drivers a big favor.

Evidence of the Durham’s Truck Eater’s carnage: http://11foot8.com/

 

Northwood Truss Bridge in Grand Forks County, ND:

Not far behind the winner is this runner-up.  A truck driver carrying 42 tons of beans tries crossing a century-old pony truss bridge, which spans the Goose River and has a weight limit of three tons.  Guess what happens next and who got short-changed?   The bridge had been listed on the National Register because of its association with Fargo Bridge and Iron and it was the oldest extant in the county. Luckily the driver wasn’t hurt but it shows that he, like others, should really take a math course before going on the road again.

Waiho Bridge Disaster and Rebuild in New Zealand

This one gets an award for not only a spectacular disaster that destroyed a multiple Bailey Truss- as filmed in its entirety- but also for the swiftest reply in rebuilding the bridge in order to reopen a key highway. Bailey trusses have known to be easily assembled, regardless of whether it’s for temporary purposes or permanent.  Cheers to the inventor of the truss as well as the New Zealand National Guard for putting the bridge back together in a hurry.

Destruction of the Chania Bridge in Greece

No bridge is safe when it comes to flash flooding. Not even concrete arch bridges, as seen in this film on the century-old Chania Bridge in Greece. Flash floods undermined the bridge’s piers and subsequentially took out the multiple-span closed spandrel arch bridge in front of the eyes of onlookers. The photos of the destroyed bridge after the flooding was even more tragic. Good news is that the bridge is being rebuilt to match that of the original span destroyed. But it will never fully replace the original, period.

Spectacular Bridge Disaster (US):

The Great Ice Jam/Flood 2019:

Sargent Bridge in Custer County, Nebraska: One of many victims of the Great Ice Jam/Flood 2019.

This category was a real toss-up, for the US went through a series of what is considered one of the biggest wrath of natural disasters on record. In particular, massive amounts of snowfall, combined with extreme temperatures resulted in massive flooding which devastated much of the Midwest during the first five months of the year. The hardest hit areas were in Nebraska, Iowa and large parts of Missouri. There, large chunks of ice took out even the strongest and youngest of bridges along major highways- the most viewed was the bridge near Spencer, Nebraska, where ice jams combined with flooding caused both the highway bridge as well as the dam nearby to collapse. The highway bridge was only three decades old. Even historic truss bridges, like the Sargent Bridge in Custer County were no match for the destruction caused by water and ice.  While the region has dried up, it will take months, if not years for communities and the infrastructure to rebuild to its normal form. Therefore this award goes out to the people affected in the region.

Runner-up: Close-up footage of the destruction of the Brunswick Railroad Bridge.

Railroad officials watched helplessly, as floodwaters and fallen trees took out a major railroad bridge spanning the Grand River near Brunswick, Kansas. The railroad line is owned by Norfolk and Southern. The bridge was built in 1916 replacing a series of Whipple truss spans that were later shipped to Iowa for use on railroad lines and later roads. One of them still remains. The bridge has since been rebuilt; the line in use again.

Best Example of Restored Historic Bridge:

 

International:

The Coalbrookdale Iron Bridge after restoration: Tk420 [CC BY-SA (https://creativecommons.org/licenses/by-sa/4.0)%5D
Coalbrookdale Bridge in the UK: 

The world’s first cast iron bridge got an extensive makeover in a two-year span, where the cast iron parts were repaired and conserved, new decking was put in and the entire bridge was painted red, which had been the original color when the bridge was completed in 1791. The jewel of Shropshire, England is back in business and looks just like new.

King Ludwig Railroad Bridge in Kempten, Germany:

The world’s lone double-decker truss bridge made of wood, received an extensive rehabilitation, where the spans were taken off its piers, the wooden parts repaired and/or replaced before being repainted, the piers were rebuilt and then the spans were put back on and encased with a wooden façade. A bit different than in its original form, the restored structure features LED lighting which shows the truss work through the façade at night.

 

 

US/Canada:

Longfellow Bridge: Lstrong2k [CC BY-SA (https://creativecommons.org/licenses/by-sa/1.0)%5D
Longfellow Bridge in Boston:

This multiple-span arch bridge with a draw bridge span underwent a five-year reconstruction project where every aspect of the bridge was restored to its former glory, including the steel arches, the 11 masonry piers, the abutments, the four tall towers at the main span and lastly the sculptures on the bridge. Even the trophy room underneath the bridge was rebuilt. All at a whopping cost of $306 million! It has already received numerous accolades including one on the national level. This one was worth the international recognition because of the hours of toil needed to make the structure new again.

Link: https://en.wikipedia.org/wiki/Longfellow_Bridge

Winona Bridge in Winona, MN:

The runner-up is a local favorite but one that sets an example of how truss bridge restoration can work. The Winona Bridge went through an eight-year project where a new span carrying westbound traffic was built. The cantilever truss span was then covered as it went through a makeover that featured new decking, sandblasting and repairing the trusses and lastly, painting it. To put the icing on the cake, new LED lighting was added. The bridge now serves eastbound traffic and may be worth considering as a playboy for other restorations of bridges of its kind, including the Black Hawk Bridge, located down the Mississippi.

And with that, we wrap up the Author’s Choice Awards for 2019. Now comes the fun part, which is finding out which bridges deserve international honors in the eyes of the voters. Hence, the Bridgehunter’s Awards both in written form as well as in podcast. Stay tuned! 🙂

Paper Mill/Marshall Bridge: Rising from the Ashes- An Interview with Julie Bowers

 

bhc interview new

What is considered the impossible became the impossible. David never gave up on the notion of beating Goliath until it actually happened. Some heavily favorites can fall to the underdogs. All it takes is patience, preserverence, passion and persistence- the four Ps to success. Five if you want to include politics.

For Julie Bowers and the crew at Workin Bridges, those five Ps were needed plus some personnel with expertise and just as much of the five Ps to bring a bowstring arch bridge back from the rubble, resurrect the structure, restore it to its former glory and now, it’s being reused for recreation. That is the story behind the history of the Marshall Bostring Arch Bridge located now at the Auburn Heights Preserve in Delaware. It has gone by many names, but two come out as the most commonly used aside from its official name: the McIntyre Bowstring Arch Bridge when it was in Iowa, and most recently, Paper Mills Bridge. The bridge has come a long way after it was destroyed by flooding in August 2009 at its original location in Poweshiek County, spanning the Skunk River. After it was pulled from the river and stored, efforts were undertaken to restore it, which included a long journey to its new home in Yorklyn, Delaware. The Odyssey came with a lot of challenges, as you will see in the interview I did with Julie Bowers before Christmas.  I wanted to find out how the 5 Ps played a role in bringing the bowstring arch bridge that is like a family to her and the crew who restored it back to life. Here’s how the story happened. Enjoy! 🙂

 

1. Tell us briefly about yourself and your role in restoring historic bridges. I’ve been doing this for ten years. I knew nothing about bridges or restoration or bureaucratic politics when our bridge was lost to the N. Skunk River. I did have a background in construction, architecture and databases and used that as a base to build on. I don’t give up and have been called stubborn. We could not do this without a lot of sacrifice by everyone that travels to save a bridge but mostly we couldn’t do it without Bach Steel and Nels Raynor and our board of directors, both current and past.

 

 

  1. In your opinion, how special is the Paper Mill Bridge (PMB) in terms of its history and personal association with it?

It was erected in 1883, built by the King Iron Bridge Company. We think it is from around 1878 production design based on the lacing in the vertical outriggers and the castings. The bridge of many names (Skunk River Bridge, Humpback Bridge, McDowell for a minute then McIntyre, then Paper Mill) now the Marshall Family Bridge, is the heart of the Auburn Heights Preserve in Yorklyn, Delaware. A public / private partnership to clean up zinc laden habitat, to rebuild old warehouses including the Paper Mill and to build a trail system using historic bridges. If we had not had this project we would not have saved our bridge. It was a lot more work after falling in the river but it will live on.

bowers2

  1. Prior to its relocation from Iowa to Delaware, the PMB was once known as the McIntyre Bridge. Tell us about the bridge in its original location.

The bridge was located on River Road over the N. Skunk River in SE Poweshiek County. Our family had ties to the area and found ourselves there often for fall and winter picnics. When I returned to Iowa in 2001, we restarted those picnics. It fit it’s location perfectly and was safely in a park until flooding pushed it off it’s piers.

 

  1. In 2010, floodwaters swept the bridge off its foundations and caused severe damage. Tell us more about it and how it influenced your decision to restore the bridge.

My daughter and I found the bridge on the Sunday following Friday the 13th. We heard later the county crews were pulling trees up river that were compromising a concrete span. They came on down river and the roots entangled with the cable railing and pushed the span off the piers. It was our bridge, my family had been tied to that place for generations and I got the call. What are you going to do? We started educating ourselves, making calls, and figuring out our options. Turns out, all we needed was Bach Steel at that time, before the bridge went down.

 

  1. What was the plan for restoring the McIntyre Bridge in its original place and why did it fail?

It was just decisions that let us keep trying to figure out how much it cost and how to find the funds. There were setbacks, grant rejections, a lot of them, but we persevered. Our first plan was research, we were referred to Vern Mesler and Nathan Holth and had them  come to Iowa. We raised $3000 for that consult.  The bridge was still up at that point. When the bridge fell we were told about Nels Raynor and we proceeded with Nels to pull the bridge from the river and to work with us on this bridge and others. My daughter, Laran Bowers is on the board now, has been for years and that makes sense. She was the one that found the bridge. Jaydine Good rounds out the board and we have about 5 advisors that we utilize all the time for their perspectives. We wrote grants to the State Historic Preservation Office (SHPO), getting our County involved.

They subsequently reneged on their commitment to a TAP grant and we knew grants would never be our solution. When the county commissioners took back their backing, we knew that the solution was not going to be there and started looking. Flooding in August of 2009 changed everything from restoration plans to salvage, then restoration. No one ever decided not to save the bridge, it was always our number 1 priority through all of our efforts. We’ve educated a lot of folks on knowing the project before deciding to continue or not. We always knew our project costs from the beginning.

 

 Author’s Note: TAP stands for Transportation Alternative Program which focuses mainly on bridge rehabilitation/restoration instead of replacement.

 

6.  What happened to the McIntyre Bridge afterwards?

It went to Bach Steel for storage while we tried raising funds. Then we brought it back to Iowa because SHPO said we had moved the bridge out of Iowa. Then SHPO delisted the bridge because it was moved off it’s piers, they didn’t believe our scope and estimate, and the bridge was stored while we worked on other projects, became a contractor and tried earning funds rather than asking for funds.

 

Author’s Note: The bridge was listed on the National Register of Historic Places in the 1980s along with two dozen other bowstring arch bridges in Iowa. Because of its significance, grants were available to restore the bridge but only at its original location. The bridge can be delisted if it’s either altered beyond historic recognition, destroyed by natural disaster or demolition or moved to another location. Some exceptions do apply.

 

7. How and when did the opportunity to relocate and restore the McIntyre Bridge come about?

Nels Raynor and I worked with Project PATH at PennDOT with Kara Russell and Preservation Pennsylvania, providing scope and estimates on several bridges. Without that information it is very hard to sell a bridge in their program. That lead to a call from DNREC. McIntyre Bridge was certainly our choice although Nels would have preferred others that might not have had as much damage. It was a lot of work and the care that Derek and Lee and their crew put into the restoration was immense. There was twisting along the box chord but if you look close today, you will see very little distortion.

8. How was the bridge reconstructed?

Very carefully. It’s a bridge that will take pedestrians and we care. This is a bowstring truss. The eye-bars are connected with castings and pins to make the length  of the bridge and the verticals hit the eye-bars, connected with cast parts. The trusses were laid opposite to each other, so that they could be picked up nearly in place and then the lateral connections were put in. Miles of angle were welded together to make the vertical “star iron / cruciform posts that were beyond repair. This is what we call in-kind restoration which means if we have to recreate parts we do that.  The trusses required mending, heat straightening, pack rust removal and it took a long time to essentially rebuild our bridge. Nels did that for us because he said he would.

9. Who were the actors involved in the restoration?

There were no actors involved. It took the expertise of Nels Raynor at Bach Steel along with his crew over years. It also took finding James Schiffer, P.E. Now he does some work for others but the original team of Workin Bridges was Nels, Jim and I. Derek and Lee Pung worked the most on the bridge, along with Nels son Brock and others that have learned iron working arts during this project.

10. What other factors led to the success in restoring the bridge?

Perseverance, not patience, and finding other work along the way, not just waiting around for grants and then deciding grants and donations aren’t enough. We started working the construction angle to have the funds to pay for overhead while some grants were pursued. Remember, you can’t do anything after the grant goes in. 6 months to wait for denial is no fun. As we went along we found more and more opportunities and we know what failure looks like. The board, under the direction of my father Dick Bowers, Gary Sanders, Diane Roth, Laran Bowers and now Jaydine Good have kept me pursuing the best outcome for our bridge and helping other people with their bridges.

 

11.  The bridge was renamed Paper Mill Bridge and later Marshall? Why was that? 

The Marshall Family owned the Paper Mill and the Mansion and a collection of vintage Stanley Steemers and other collectible vehicles. They donated this to the state parks system and DNREC wanted to honor the family by naming the bowstring after them. Marshall Family Bridge was dedicated last year while Mr. Marshall could be there.

 

12.  Paper Mill Bridge is now in Delaware, but there is talk of adding some bridges, a couple from Pennsylvania. Can you elaborate further on this?

Part of Project PATH was a pony truss bridge for sale that we added to the complement of bridges from York County, PA. The project criteria were to find bridges with different builders, types and ages from different states to complement the mills being restored. That bridge, now called Farm Lane, is a pony truss that we modified for strength and width with girders. We also widened it to allow for a pedestrian lane, and engineered it for vehicular traffic with a moveable railing if emergency or agricultural vehicles need to cross. Martin Road will become Snuff Mill. A pratt truss from Michigan has been restored and is being painted, awaiting installation at NVF.  Another large truss, the Portland Water Works bridge is in storage in Delaware for future installation after we purchased and transported it across country two years ago.

 

 13.     How would you theme the project, Saving the Paper Mill Bridge either as a title or in one sentence? The Skunk River Bridge Story – 1883 to present

 

14.   What future bridge restoration projects do you have on the agenda, especially the bowstring arch bridge, like the Paper Mill?

We are working on Watts Mill Road Bridge, a rare continuous pony truss, we have tried to take on Aetnaville Bridge in Wheeling as a restoration project knowing that $2.5 million could be useful for preservation. We saved the Springfield Des-Arc bridge in a new park, that was another bowstring. I think we are instrumental in Pennsylvania and Ohio utilizing Bach Steel to save bowstrings now. If they are the Kings of Kings, we know where that started. Any that we can find now will go into the “Bridge in a Box” sales program that we are developing. Of course we expanded on the Old Richardsville Bridge and are hopeful that the engineers will be required to work with us on the restoration needs. We found little to fix but the Kentucky Cabinet likes spending funds on local certified engineers, lots of money. We got the process started to showcase that it was much older and it will be preserved as a vehicular bridge. That took historical research from the bridge hunting community which was great to dial in the history that negated the NPS dates for NRHP.

 

 15. What words of advice would you give to those who are pursuing preserving and reusing a historic bridge, based on your personal experiences with this bridge?

It is always political. Find the economic benefits for the bridge to the local community. You can’t assume that they will take it on like Beaver County did with Watts Mill Road Bridge after it is reset. Engineers estimates are overly high so get another opinion. Engineers are asked specific questions by their clients that they answer – their answers don’t always look at preservation. For instance, the engineers estimate for Broadway Bridge in Frankfort assumes putting concrete back on it and doesn’t even consider planks or an engineered decking system. Some DOTS are really working hard at finding solutions, but we have to become competitive in selling a “Bridge in a Box – by Bach”  if we want to be competitive with those selling welded steel spans. Convincing and branding a membership driven “Workin'” non profit would create funds annually to help save bridges and other structures. We’ve looked into many ideas, some have merit, some do not. For now we do site visits that give real costs for restoration so that our clients can have enough information for good decisions to be made. We will be crafting more stories on video and perhaps a book on the McIntyre – we have footage of my father and other locals when we first started. We also have content on a lot of site visits that we will start to analyze and put out as well. Having a wonderful board that won’t let you give up even in the face of struggles is the secret. There will be struggles and set backs. Engineers want to build new bridges and cities don’t want the risks of old ones. We try to mitigate the risks.

It’s hard. We’ve learned a lot of valuable lessons as we pursued this. No good deed ever goes unpunished but there are a lot of great people and wonderful stories across the US. We saved our bridge but it took a lot out of all of us and it wasn’t the outcome we wanted but it was the best outcome for the bridge. Can’t wait to walk it again soon.

Epilog: The Paper Mill/ Marshall Bridge has received a lot of national and international recognition after its reconstruction and re-erecting at its new home in Delaware, including the 2018 Ammann Awards for Best Example of a Restored Historic Bridge and Bridge of the Year, edging out the Blackfriar’s Bridge in Canada, whose design is similar to this bridge. While Blackfriar’s still retains the role of being the world’s longest of its kind, this bridge will definitely go down in the history books as one which was resurrected after a tragedy and is now being used again after years of hard work and lots of expertise. It sets the foundation for other historic bridge restorations that will come in the new decade, for they are becoming more important to save for future generations as the numbers dwindle due to progress and environmental disasters that are partly due to that progress. Progress is not welcomed unless we see some advantages in these. And as we learned this year with Greta Thunberg’s world tour, the environment will indeed be priority number one in our future plans for making things better. This is one of the projects that will benefit many.

BHC FORUM

After processing the candidates and adding some information to some of them, the time has come to vote for our favorite candidates in nine categories for the 2019 Bridgehunter Awards, powered by the Bridgehunter’s Chronicles. As mentioned earlier in the year, the Ammann Awards were changed to this name to honor some of the pontists, whose category and prizes have been named in their honor. Nevertheless though, the format is the same as in the previous awards. There are two voting ballots- one here and one on the next page (which you can click here). With the exception of the category Best Photo, each candidate has a link which you can access so that you can look at them more closely in terms of photos and information.

For Best Photo, I’ve decided to do it differently. One simply looks at the photos and votes. The names of the top six (including the winner) will be announced.

Voting is unlimited due to the high number of candidates in each of the categories- both on the US level as well as on the international level- and because many of us have multiple preferences than just one. 😉

Without further ado, here’s part I of the voting ballot and have fun voting. 🙂

HOLT, MICHIGAN/ GRINELL, IOWA-  The long-awaited documentary by Ultimate Restorations on historic truss bridge restoration is now available for viewing at www.ultimaterestorations.com or Amazon Prime. Featuring the 1874 Springfield Des-Arc Bridge, an historic King Iron Bridge Co. bowstring truss in Conway, Faulkner County, Arkansas, the two episodes document how an engineer, craftsmen, two nonprofits, a city, county and state worked together to save a rare historic bridge in the USA. Local screening are also being scheduled.

Bach Steel of Holt and St. Johns, Michigan provided the iron restoration expertise. The craftsmen, Nels Raynor, Derek Pung, Brock Raynor and Lee Pung put their backs into this project from riveting to pack rust removal, repairing splice plates, lifting and resetting old iron. Jim Schiffer, PE of Schiffer Group Engineering, Traverse City, Michigan. (SGI) worked with Bach Steel to detail the repairs. SGI also engineered the caissons by request from Julie Bowers at Workin’ Bridges who just didn’t want to see another concrete abutment for the historic truss. “These are the kinds of projects we relish. The reuse and preservation of durable cast and wrought iron and steel, that are still serviceable with a little coaxing, to recreate elegant functional forms that the communities can enjoy is really fun. These are the projects that we enjoy applying our technical experience and training to bring to successful completion.” stated Jim Schiffer after viewing the video. Though you don’t see him in the site work, without his engineering neither Workin’ Bridges nor Bach Steel would be able to act on these jobs.

Working with the City of Conway and Faulkner County, the planning and iron work for the restoration of this bowstring took well over a year after lifting it from the North Fork of the Cadron River. The bridge was restored and reset at Lake Beaverfork in August of 2016. The project began, however, with a site visit in 2010 to discuss the potential of the oldest road bridge in Arkansas, also a King Iron bridge. The project required the aid of the Prof. Kenneth Barnes, then a director of the Faulkner County Historic Society to continue raising the awareness that this vintage bridge needed help. Many of these stories can be seen on the video.

Bach Steel has worked on over 40 historic bridge projects across the country, winning awards for their work in Texas, Michigan and Arkansas since the 1990s. “The Springfield Bridge tells a story of one of the projects that we started with Workin’ Bridges in 2010 and it took years to fund it. There are so many bridges across the country that can be restored but it takes political will, our engineer, money and us to get it done….and big cranes!” stated Nels Raynor at the shop in St. Johns.

Ultimate Restorations produced the shows out of the bay area. Producer Terry Strauss along with Executive Producers Bill Hersey, Loren Lovgren, and Bob McNeil have documented the restoration of some of America’s beloved treasures. “The story of this bridge is what Ultimate Restorations is all about. The vision to save the iconic pieces of our history that would otherwise be lost, plus the skills, passion and talent to bring them back to life. Walking over that bridge, is like being told a story, reminding us of who we are and where we’ve been.” said Terry Strauss, who directed the film in Arkansas.
