To honor the reopening of a key historic icon, this Pic of the Week takes us back ten years and to Winona in Minnesota. During my visit in 2010, I took a ton of photos of the Winona Bridge, a 1942 cantilever through truss bridge that spans the Mississippi River at the Minnesota-Wisconsin border, carryinh Highway 43. While I got a lot of angles and listened to some interesting stories about the bridge, including one from a gas station attendant who used to be a female wrestler (she even looked like one of my heroes, Sara Del Rey), this shot from the Wisconsin side was probably the best one of the bunch. Even with the new bridge running alongside the newly restored historic bridge, this photo vantage point would be highly recommended if you want to get a shot of just the cantilever bridge itself, even when lit with LED at night.

After record-setting snowfall and cold in the Midwest of the US, residents and farmers are bracing for what could be flooding of biblical proportions. Already in Nebraska, Iowa, South Dakota and Wisconsin, one can see fields converted into lakes and piles of broken ice from rivers and lakes littering streets and Highways. Billions of Dollars in property lost are expected as floodwaters and ice have destroyed farms and killed livestock, while many houses are underwater with thousands of residents displaced. Highways and especially bridges have been washed away, while other forms of infrastructure have caved in under the pressure of high water caused by snowfall, ice on the ground and massive amounts of precipitation. For residents in Minnesota, North Dakota, Illinois and regions along the Mississippi and Missouri Rivers, where people are sandbagging their homes and communities, while others are evacuating, the scenes out west are a preview of what is yet to come.
The same applies for many historic bridges and other key crossings, for reports of bridges being washed away by flooding or crushed by ice jams are cluttering up the newsfeeds, social media and through word of mouth. While dozens of bridges have been affected, here’s a list of casualities involving all bridges regardless of age and type that have come in so far. They also include videos and pictures. Keep in mind that we are not out of the woods just yet, and the list will get much longer before the floodwaters finally recede and the snow finally melts away. For now, here are the first casualties:
Bridge Casualty List:
Trolley Bridge in Des Moines, Iowa: Spanning Beaver Creek north of I-35 between Iowa’s State Capital and nearby Johnston, this railroad trestle with two deck plate girder spans used to serve a trolley line going along the creek to the northwest. The line and the bridge were converted into a bike trail in 2000. On Wednesday the 13th, an ice jam caused by high water knocked over the center pier, causing the two deck plate girders to collapse. Two days later, the spans floated down the river with no word on where they ended up. No injuries reported. It is unknown whether the bridge will be rebuilt.
Highway 281 Bridge in Spencer, Nebraska: The Sandhills Bridge, spanning the Niobrara River was built in 2003. The multiple-span concrete beam bridge is located south of Spencer Dam. It should now be reiterated as a „was“ as the entire bridge was washed away completely on Monday the 11th. A video shows the bridge being washed away right after the dam failure:
The main culprit was the failure of the Spencer Dam, caused by pressure from high water and ice. It is unknown when and how both the failed will be rebuilt, even though sources believe the bridge will be rebuilt and open by September.
Carns State Aid Bridge in Rock County, Nebraska: This Niobrara River crossing consists of five arch spans, a Parker through truss and a Pratt through truss- both of them were brought in in 1962 to replace a sixth arch span and several feet of approach that were washed away. The bridge ist he last surviving structure that was built under Nebraska’s state aid bridge program and is listed on the National Register. It may be likely that a couple additional spans will be needed as the south approach going to the truss span was completely washed away in the floods. Fortunately, the rest of the bridge is still standing.
Sargent Bridge:Residents in Custer County, Nebraska are mourning the loss of one of its iconic historic bridges. The Sargent Bridge was a two-span, pin-connected Pratt through truss bridge with Howe lattice portal bracings supported by 45° heels; its overhead strut bracings are V-laced with 45° heels as well. Built in 1908 by the Standard Bridge Company of Omaha, using steel from Illinois Steel, this 250-foot long span was no match for large chunks of ice, floating down the Middle Loup River, turned the entire structure into piles of twisted metal. This happened on the 14th. While a photo showed only one of the spans, it is unknown what happened to the other span. One variable is certain: The loss of this historic bridge is immense.
Green Mill Bridge near Waverly, Iowa:Time and wear took a toll on this two-span bowstring through arch bridge, which spanned the Cedar River between Janesville and Waverly. A product of the King Bridge Company, the bridge was part of a three-span consortium in Waverly when it was built in 1872. 30 years later, two of the spans were relocated to a rural road northeast of Janesville, where it survived multiple floods, including those in 1993 and 2008. Sadly, it couldn’t survive the ice jams and flooding that took the entire structure off its foundations on the 16th. Currently, no one knows how far the spans were carried and whether they can be salvaged like it did with the McIntyre Bridge in Poweshiek County. The Green Mill Bridge was one of only two multiple-span bowstring arch bridges left in the state. The other is the Hale Bridge in Anamosa.
Jefferson Viaduct in Greene County, Iowa: The Raccoon River trestle features a through truss span built by Lassig Bridge and Iron Works and trestle approach spans built by the both Wisconsin Bridge and Iron Works and the Chicago Bridge and Iron Works Company. The 580-foot long bridge used to serve a bike trail until Friday the 15th when ice took out several feet of trestle approach. Fortunately, the through truss span is still in tact. Given its location though, it may take months until the trestle spans are replaced.

Turkey River Railroad Bridge at Millville, Iowa: This railroad span, located near 360th Street in Clayton County, has not had the best of luck when dealing with flooding. The two-span through truss span was destroyed in flooding in 1991 and subsequentially replaced by three steel girder spans. Two of them were washed away in flooding in 2008 and were replaced. Now all three spans are gone as of the 15th as flooding washed them all out. The rail line, owned by Canadian Pacific, has been shut down until a replacement span is erected with the freight trains being rerouted. It does raise a question of whether having a span in a flood-prone area makes sense without raising the railroad line.
Dunham Park Bridges in Sioux Falls, South Dakota: One of the first cities hit by ice jams and flooding, Sioux Falls was almost literally underwater with floodwaters at every intersection and street as well as the Falls being converted into an apocalyptic disaster, resembling a dam failing and the waters of the Big Sioux River wiping out everything in its path. One of the hardest hit was seen with Dunham Park as floodwaters washed away two mail-order truss bridges almost simultaneously. A video posted in social media on the 14th showed how powerful the floodwaters really were. The bridges were installed only a few years ago. It is unknown if other bridges were affected as crews are still battling floods and assessing the damage. It is however safe to say that the park complex will need to be rebuilt, taking a whole summer or two to complete.
There will be many more to come, as the weather gets warmer, accelerating the snowmelt and making the situation even more precarious. We will keep you informed on the latest developments. But to close this Newsflyer special, here’s a clip showing the raging Big Sioux River going down the Falls in Sioux Falls, giving you an idea of how bad the situation is right now:
That in addition to a reminder to stay away from floodwaters. Signs and barricades are there for one reason- to save your life. Think about it.
Our thoughts and prayers to families, friends and farmers affected severely by Mother Nature’s wrath- many of them have lost their homes and livelihoods and are in need of help. If you can help them, they will be more than grateful…… ❤
150-year old covered bridge loses roof in snow collapse. To be rebuilt pending on degree of damage.
ZUMBROTA, MINNESOTA (USA)- Record-setting February snowfall in the Midwest is starting to take its toll on its infrastructure due to the development of potholes and cracks on the roads. It is also taking its toll on the architecture, for too much snow on the rooves of houses and covered bridges- especially heavy, thick snow- can cause a roof to cave in.
Ask the people in the town of Zumbrota, located between Cannon Falls and Rochester in Goodhue County in southeastern Minnesota. Their prized centerpiece of the community of over 500 inhabitants has an uncertain future as the Zumbrota Covered Bridge partially collapsed over the weekend.
Built in 1869, the covered bridge is a Smith through truss, which is similar to a Lattice truss with diagonal beams criss-crossing each other, except its outer diagonal beams represent an end-post angled at 30°. The bridge was rehabilitated in 1932, 1950 and again in 1997, when the 120-foot long structure was moved 100 yards downstream to a park, which is situated just off Hwy. 58. It had previously crossed at Main Street. The park covers much of the eastern shore of the North Branch Zumbro River and provides people with some recreational possibilities. The structure has been listed on the National Register of Historic Places since 1975. Even though there had been another covered bridge of its kind built for a railroad north of Zumbrota, this covered bridge is the last one in service in the state of Minnesota.
As you can see in the Picture above, presented by mayor Bradley Drenckhahn, this was not what people had expected from the bridge. This was taken on the 24th, just after the roof of the covered bridge caved in, which had happened sometime overnight. Fortunately, no one was injured.
It is unclear if the center pier, built the same year the covered bridge was relocated, was affected by the collapse. The degree of the collapse will be inspected by transportation officials. The fortunate part is that the bridge is insured and town officials will rebuild the bridge once the snow has melted. The question is: just the roof or the whole structure? This is important for it could affect the upcoming events commemorating the covered bridge’s 150th birthday. According to its website, the covered bridge festival will take place on June 15th and 16th, whereas the birthday celebrations will be August 3rd and 4th. Both will take place at the park. How the collapse and the subsequent reconstruction will affect the festivities remain unknown.
A link to the covered bridge website is available and can be clicked here. The Chronicles will keep you posted on the latest on this bridge.
Before announcing the official winners of the 2018 Ammann Awards, it’s time to take a look at the winners of the Author’s Choice Awards. Here, the author of the Chronicles (yours truly) picks out the best and worst in terms of bridges. And for this year, there is plenty of fame to go around. So without further ado, let’s take a look at my picks to close off a busy year.
Spectacular Bridge collapse
Florida International (niversity Bridge in Miami- There are accidents with fatalities that are caused by natural disasters, then we have some caused by human error. The Florida International University Bridge in Miami, which had been built by FIGG Bridge Engineering was one that collapsed on March 15th, killing six people was one that was caused by human error. Faulty design combined with a lack of thorough inspection caused the double decker bridge to collapse in broad daylight, turning a dozen cars passing underneath into steel pancakes. Most of the fatalities were from people who were squished underneath. It was later revealed the FIGG and four other companies had violated seven regulations resulting in fines totalling $89,000. Yet they are not out of the woods just yet, due to lawsuits pending against them. It is unknown whether a new pedestrian bridge will be built.
Kingsland Bridge in Texas- We have accidents caused by mother nature that produced no fatalities and not even the most modern of bridges can withstand. A pair of runner-ups come to mind on the American side: The bridges that were lost in the worst forest fire in California history, and this one, the Kingsland Viaduct, a 50-year old bridge spanning Lake Llano that was washed away by floodwaters on October 6th. Fortunately here, no casualties were reported. A new bridge is being built.
Morandi Viaduct in Genoa, Italy- It was the collapse of the year. The Morandi Viaduct in Genoa in Italy collapsed on 14 August during a severe storm. 22 people were killed, many of them had been crossing the concrete cable-stayed suspension bridge at the time of the collapse. The work of bridge engineer Ricardo Morandi had been under scrutiny due to defects in the decking and concrete cables and it was a matter of a simple storm to bring part of the bridge down. It served as a wake-up call for the Italian Government as it introduced strict standards for bridges afterwards, also in Europe. Other Morandi bridges are being examined with replacement plans being put together. As for this bridge, the 54-year old structure is currently being replaced with a steel/concrete beam viaduct, which is expected to be finished by 2020.
Chiajara Viaduct in Colombia- Runner-up here is another cable-stayed bridge, but located in the forest near Bogota. Here one didn’t need a storm to bring down the partially-built bottle-shaped cable-stayed suspension bridge, which happened on 15 January. 200 people were attending a seminar when the collapse happened, unfortunately those who were on the bridge- about 20 workers- were not so lucky. Eight were killed and others were injured, some critically. The completed half of the bridge was taken down six months later. It is in the process of being rebuilt.
Biggest Bonehead Story:
We had a lot of eye-rolling and forehead-slapping stories in this category. So we’ll start at the place where anything can happen: The United States
Man Destroys Historic Bridge in Indiana, Gets Sentenced and Asks for a Retrial- This really bonehead story goes back to the now extant Hohmann Railroad Bridge, which used to span the Grand Calumet River near Hammond. The person was arrested and tried on federal charges of not only trespassing onto the bridge, but destroying property for the sake of scrap metal- without even a permit. His claim: no one owns it so the metal was his. He was sentenced to 10 years in prison without parole, yet he just recently asked for a retrial- for treating him unfairly in court and for wrongful judgement! Mr. President (Donald J. Trump): I have the perfect candidate for you to replace Elaine Chao as Head of the US Department of Transportation! He’s that type of guy!
Truck Driver Destroys Covered Bridge in East Chicago Days after Its Reopening- If the mother of this driver was at the scene of this rather careless accident, the person would have had a lesson of a lifetime, known as You break it, you fix it! On 28 June, 16 days after it reopened and was designated as a historic structure, Mr. Eriberto Orozco drove his truck through the covered bridge, ignoring the warning signs and sensors, and plowing smack dab into the newly restored structure. When he got out of the truck, he smiled. He has since been cited for reckless driving and destruction of property. The covered bridge is considered a total loss.
Three-Bridge Solution in Saxony- The battle between preservation and progress got a bit hairier and went way over the top with this story: A stone arch bridge had to be rebuilt elsewhere, moved aside for a modern bridge. Unfortunately, as you can see in the video, things went south in a hurry. Watch and find out what happened and why we have three bridges instead of one. The story is in the documentary Voss & Team and starts in the 11th minute.
Best example of a restored historic bridge:
Blackfriars Street Bridge- This year’s awards are the year of the bowstring arch bridge for there were some great examples of restored bridges of this kind that have been reported. While the Paper Mill Bridge won the Ammann Awards in two categories, the Author’s Choice goes directly to the Blackfriars Street Bridge because of the painstaking task of dismantling, sandblasting and repairing (in some cases replacing) and reassembling the structure back into place. All within 18 months time, keeping the historic integrity in mind and the fact that the bridge still holds the world’s record for longest of its kind. This is one that will be discussed in the historic bridge community for years to come and one that deserves some kind of recognition of sorts.
A pair of bridges visited during my US trip definitely deserve some recognition for its work. The Broadway Avenue Bridge in St. Peter, Minnesota is one of them. The 1930s two-span through truss bridge underwent a makeover in 2017 with new decking and lighting, fixing some truss parts and a new coat of paint. The forest green colored bridge looks like it was newly built. It’s definitely one for the ages. The other bridge worth noting is the State Street Bridge in Bridgeport, Michigan. The 112-year old two-span Pratt through truss bridge was restored in 2016 where the trusses were taken apart, sandblasted and painted. Some of the truss parts were bent and needed to be straightened. A new pier and new decking followed. The bridge is now one of the key components of the county historical museum, where a collection of historic houses and a park line up along Main Street, adjacent to the Cass River crossing.
The Hidden Gem: Best Find of a Historic Bridge
Originally meant for finding only one historic bridge, I had to make some exceptions for two of the notables that deserve to be recognized. Henceforth, let’s have a look at the winners of the Author’s Choice in this category:
The Bridges of White County, Illinois- Fellow Bridgehunter Melissa Brand-Welch found a collection of abandoned truss bridges in this southeastern Illinois county, each of which had its unique design and history. There are at least six through truss bridges and numerous pony trusses that one can find here. Each of them have potential to be restored and reused as a bike/pedestrian crossing. This county got second place in the category of Tour Guide for American Bridges in the 2018 Ammann Awards, while Ms. Brand-Welch won in the Best Bridge Photo category with her oblique photo of the Siglar Bridge. Winning the Author’s Choice Awards in this category should be the third and most convincing reason for county officials to act to collaborate on saving these precious structures. If not, then Ms. Brand-Welch has at least three accolades in her name.
Camelback Girder Bridge in Wakefield, Michigan- Runner-up is this small crossing. Michigan is famous for its camelback girder bridges of concrete, for dozens were built between 1910 and 1925. This bridge, located 500 feet away from a park in Wakefield, is easy to miss unless the oversized chair next to the shelter catches you. Then during your stop for a photo and picnic, you will see it. May be a boring concrete structure to some, but it is unique enough for a brief stop.
In the international category we have three bridges that deserve recognition because they are either rare to find or are rarely recognized by the public. We’ll start off with the first bridge:
Höpfenbrücke in Pausa-Mühltropf (Vogtland), Germany- Located just off a major highway, 15 kilometers west of Plauen in Saxony, this bridge was built in 1396 and was an example of a typical house bridge- a bridge with houses either on the structure or in this case, on the abutments. This structure was restored recently after flood damage forced its closure. The bridge is definitely worth the stop as it is one of three key points the village has to offer. The other two are the palace and the city center, where the bridge is located in.
Pul Doba Suspension Bridge- One of the fellow readers wanted some information about this bridge. It is one of a half dozen in India whose towers is shaped like one of the towers of a castle. It was built in 1896 but we don’t know who built it. We do know that this bridge is a beauty.
The Bridges of Conwy, Wales- How many bridges does it take to get to a castle? Three, according to the city of Conwy in Wales, which has three structures that lead to one of the most popular places in the country: an arch bridge for traffic, a chain suspension bridge for pedestrians and a box through girder with towers for trains. Not bad planning there, especially as they fit the landscape together despite its space issues with the channel and the penninsula.
This sums up my picks for 2018. While we will see what 2019 will bring us for historic bridges, we will now take a look at the results of the Ammann Awards, which you can click here. Remember the results include a podcast powered by SoundCloud.
Our 28th Pic of the Week takes us back to 2007 and this bridge in Minnesota- the Kern Bridge. Located south of Mankato, this 1873 product of Wrought Iron Bridge Company is the longest bowstring arch bridge in the US, with a span of 190 feet. It is the second longest in the world behind the Blackfriar’s Bridge in London, Ontario (Canada). The bridge has been closed since 1990 and has been sitting abandoned ever since. Unless something can be done to rehabilitate the bridge, the structure is on the verge of collapse with a cracked abutment and missing planks according to the latest visit by James Baughn. Currently, there is some collaboration behind the bridge’s future in terms of restoring it for reuse. Yet lack of funding and the will to restore it is still imminent We’re looking for some ideas as to what to do with this structure. Does anybody have any ideas?
