BHC Mystery Bridge

Approximately two weeks ago, I did a write-up on the Castlewood Thacher Truss Bridge, which had once spanned the Big Sioux River just outside Castlewood in Hamlin County, South Dakota. The bridge was listed on the National Register of Historic Places in 1993 but not before it was bypassed by a low-water crossing. On GoogleMaps, one can only see the lally columns and the wing-walls but no truss structure. My question was “Where’s the Bridge?”

Many people thought the bridge was long gone, however…….

The bridge is still alive and well- but in a new home! 🙂 ❤

Jennifer Heath made a stop at the Threshing Grounds located outside Twin Brooks in Grant County and found the Thacher structure in use. Thanks to Don Morrison, who added the coordinates in my article from 20 February, she took a brief stop at the bridge a couple days ago to cofirm the bridge’s existence.

According to the information posted on the sign, the bridge was re-erected at the site in 1998, which meant that it had been taken off its original piers at Castlewood prior to 1997 and moved to this site. The bridge still serves traffic and is one of key features of the Twin Brooks Threshing Show Grounds. Featuring historic buildings (relocated here), farm exhibitions and a flea market, the Grounds hosts the annual threshing show in August, featuring antique tractor pulls and other forms of entertainment. It’s unclear how long they’ve been hosting the event or what the motive behind purchasing this historic bridge was. However it is clear that this bridge is the second of three hybrid Thacher structures that was relocated to a historic town setting to be used for exhibits and entertainment. The Yellow Bank Church Bridge in Laq Qui Parle County, Minnesota made its home at the Little Log House Pioneer Village, south of Hastings in Dakota County, Minnesota, when it was relocated there in 1989 and serves as a replica of the city’s beloved Spiral Bridge. The Castlewood Bridge sits over the creek and on concrete shows; its decking appears to be concrete, which makes carrying tractors and trucks a possibility.

While more information on the creation of the Grounds and the relocation of the bridge is needed (and will require a few e-mails and phone calls to find out -stay tuned), the bottom line is that the Castlewood Bridge has been found and is still serving traffic- 22 years after its relocation from its Big Sioux crossing. And it appears that with as much care as it has been taken, this bridge will remain a key ornament for the Grounds for many years and generations to come. For Twin Brooks, as well as Grant County and the state of South Dakota, it is a win-win situation, when someone preserves a key piece of history and uses it for a tourist attraction. 🙂

Which makes me wonder whether the Ellsworth Ranch Bridge in Emmet County, Iowa will be the next candidate to make such a move….. And if so, where to? 😉

Mystery Bridge Nr. 128: The Disappearing Thacher Truss Bridge in Castlewood, SD

BHC Mystery Bridge

This Mystery Bridge entry takes us to the town of Castlewood in Hamlin County, The town is located east of the Big Sioux River, which snakes its way through the field in its infancy before it widens near Watertown. While Castlewood may be a typical rural American town, it does hold a treasure that is historically significant and one where we’re looking for.

The Castlewood Truss Bridge was a Thacher through truss bridge that had spanned the Big Sioux River southeast of town. It carries 184th street. The structure is 100 feet long with the main span having been 80 feet. The bridge was built by the King Bridge Company in 1894 under the direction of agent Milo Adams, and was the second of two bridges that was discovered and researched by the National Park Service in 1989. The second was at Yellow Bank Church Bridge in Laq Qui Parle County in neighboring Minnesota, built one year earlier. . Together with the Ellworth Ranch Bridge in Emmet County, Iowa, the Castlewood Bridge represented an example of the hybrid form of the Thacher Truss Bridge, which was patented by Edwin Thacher in 1881.

The bridge was listed on the National Register of Historic Places on December 9th, 1993, yet the bridge was replaced on a new alignment by a low-water crossing in the summer of 1990. According to recent satellite view, the Thacher Truss structure is no-more. All that is left are the wing-walls and the lally columns on the west bank of the river.

This leads us to the main question: What happened to the bridge?

Research in newspaper articles and correspondences have thus far come up with nothing concrete. The exception was the plan to replace the bridge in 1989 after reports revealed that the structure was rusting and no longer able to carry traffic, which ran parallel to the research into the bridge’s historic significance. Bridgehunter.com had pinpointed the replacement date as sometime after June 1990, even though the article mentioned August 1990 as its planned replacement date.

This leads us to why the Castlewood Bridge was listed before the end of 1993. According to the National Register of Historic Places, any historic structure can be listed on the register if they comply to the requirements of historic significance. Once it’s listed, then grants and funding are made available for restoring and protecting the place, and it is next to impossible to demolish the historic place unless plausible arguments are made justifying it, which includes understanding the consequences of destroying it, which is its delisting. If the Castlewood Bridge was demolished for any reason, the bridge would be delisted from the National Register, and all records pertaining to its nomination, history and the like would be archived and made unavailable for researchers. If the bridge was replaced before its nomination in 1993, why list the structure to begin with? And if it was destroyed after its listing in 1993, why is it still listed?

This leads us to the question of what happened to the Castlewood Bridge. One has to assume that the bridge was dismantled and put into storage to be reused elsewhere. This was what happened to the Yellow Bank Church Bridge, and the truss bridge now has a new home at the historic village park south of Hastings in Minnesota. Its role is mimicking the Famous Hastings Spiral Bridge, the first bridge in the world with a loop approach. With regards to the Castlewood Bridge, the question is: Where’s the bridge? And will it be reused somewhere, if it has not been re-erected already? If the bridge no longer exist, then the question is 1. Why justify its existence on the National Register, and 2. Were any bridge parts been preserved as a historical marker?

The research about the bridge’s fate has not born any fruit to date. Therefore, the question goes straight to the locals of Hamlin County, South Dakota and the residents of Castlewood with this in mind:

“Where’s the Bridge?”

BHC Pic of the Week Nr. 84

84629184_2966341866729776_4588389372784541696_o

BHC Mystery Bridge

This week’s pic of the week is also the 127th mystery bridge, both of which keeps us in Dresden. I happened to pass through this skyway while taking a group of students to the Church of our Lady (Frauenkirche) and to a popular Italian restaurant nearby. It was one I founded by chance and like in last week’s pic, this one also is a relict from the Baroque period, which survived the second World War. The question is where exactly is this bridge located? It’s near the newly rebuilt church, which means there’s a choice between Schlossstrasse and Brühlergasse, both of which are near the Dresden Castle and Semper Opera, where the skyways had been built to connect them and the cathedral. However, I’m not quite sure if this is the place.

Can somebody help, who’s from Dresden? Also nice to know of its history, if there is some available.

Mystery Bridge Nr. 124: The Bedstead Truss Bridge in Beaver County, PA

82557607_2683798111657449_8968890676196409344_o

This first mystery bridge of 2020 presents us with a black and white photo of a bridge from a bygone era. Tammy Frank provided this to Workin Bridges and needs your help in finding some information on it. It’s a photo of a Lattice pony truss bridge, located in Beaver County, Pennsylvania. Judging by the look of the car crossing it, it appears that the photo was taken between 1920 and 1925. The bridge itself has welded connections but it appears the truss style is bedstead Howe Lattice, one of the rarest truss designs built during that time because of the popularity of the other trusses (Pratt, Parker, Warren, Pennsylvania, Baltimore, etc.) Therefore that date of construction is around 1890-1910. The bridge is long gone, probably replaced 40-50 years ago.

The question is, what else do we know about the bridge? In particular, where in Beaver County, was this structure located?

Any information can be sent via mail but you can also post on the Workin Bridges website, where this pic can be found. Whatever is found, will be added to the bridge’s portfolio.

Thank you for your support and happy bridge and infohunting! 🙂

2019 Bridgehunter Awards Voting Ballot Part 1

The QEII Bridge at Dartford, east of London. It has extremely long approach ramps to get the roadway high enough to cross the River Thames while still leaving sufficient clearance for ships to pass underneath.

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. 🙂

Mystery Bridge Nr. 122: A Through Truss Bridge deep in the Erzgebirge

IMGP8998

Returning to the Erzgebirge we have a large crossing spanning the River Zwickau for a mystery bridge. Located near the village of Langenweissbach, this structure is a Warren through truss bridge with riveted connections, approximately 30-40 meters long and 4 meters wide. It carries Werkstrasse going through a series of buildings which appeared to have been either a former factory or a town before it was abandoned. The company that had existed closest to the bridge was Tarsan GmbH (Limited), but the firm closed down some years ago.

IMGP9011 (1)

Werkstrasse used to be a thoroughfare before the railroad crossing shut down. The street and its branch is now a dead end. Only one building next to the bridge is still occupied, which means the street is rarely used except for private purposes. Given the rust on the bottom chord and parts of the upper half of the superstructure, this bridge dates back to a time between 1910 and 1950, although given its remote location, it may have been spared the bombing. The structure is still used but with weight and height restrictions.

ZwSch

This leads to the question of the following:

  1. What’s the history behind the buildings along Werkstrasse: Was it a factory, a town or a combination of a few? Could it be a military camp of some kind?
  2. What’s the history behind the bridge? Was there a previous structure before this one?
  3. What’s the history behind the street the bridge crosses?

Any ideas, we’re all ears, regardless of language. So, “Hau rein!” 🙂

Langenweissbach is located between Zwickau and Aue-Schlema. First mentioned in the history books in the 12th century, the town merged with Weisbach and Grünau in 1996 and later became part of Langenbach. More on its history here.
