Stonelake Bridge (South Dakota)
Posted June 11, 2022, by Roger Deschner (rogerdeschner [at] gmail [dot] com)

It took some detective work to figure out that this distinctive Canton Bridge Co. bridge is actually listed twice in the National Register of Historic Places, under different names. I have renamed it from Horse Creek Bridge to Stonelake Bridge, which is what Wikipedia calls it, and what the 1986 NRHP entry calls it.

Mystery Solved! Susan Allen sent me this info just a couple days after it was posted:

The Crescent Street Bridge built by WPA in 1935 at Flandreau was constructed for $19,591.80 and the contract was let to J. C. Sorenson of Trent. Sorenson built a number of bridges and roads in the area based on newspaper reports. A temporary bridge was constructed west of the existing bridge while the new bridge was constructed.

Source: New Bridge will be built at Flandreau for $19,000. March 29, 1935. Argus-Leader (Sioux Falls SD), p. 16

Expect Contracts to get approval. March 15, 1935. Huron Evening Huronite, p. 11.

Now the question: what other bridges did Sorenson built and where were they located?

Posted March 2, 2022, by Jason Smith (flensburg [dot] bridgehunter [dot] av [at] googlemail [dot] com)

That may be the case as when I was there in 1998, I couldn't get close enough to the bridge due to rocky cliffs along the river. We'll leave it as is. We're still looking for the person who built it, though as it would complete the bridge's biography.

BTW, here's my Mystery Bridge article for everyone to see:

The NBI reports this as a steel stringer bridge. Being as only one photo is posted and I cannot see under the bridge, I am assuming this is a concrete encased steel stringer (a type which was most commonly built in the 1920s and 1930s). If I have made assumptions in error please let me know and I will revert the change.

Article on the collapse. I still haven't heard if it was a derailment or structural failure..

Posted January 28, 2022, by Alex Huff (dsrc512 [at] midstatesd [dot] net)

Nathan,

The area towns are small and only have weekly papers ranging from eight to twelve pages. Published on Tuesdays or Wednesdays to meet the needs of the local grocers' inserts, the bridge story missed this week's deadlines. I expect a couple will run a story next week. Ravellette Publications produces the papers. I subscribe to three of the papers and.will forward printed information to you in due course.

As an aside, it is my understanding the CNW recycled bridges from further east for use on the extension west of Pierre to Rapid City, post 1900.

Posted January 28, 2022, by Nathan Holth (webmaster [at] historicbridges [dot] org)

Alex,

Thanks for letting us know about this.. are there any news article online about this bridge collapse? I was trying to find something to post for people to read. For a bridge historian like myself this would be a far more tragic loss than the Pittsburgh bridge getting all the attention today.

Posted January 28, 2022, by Alex Huff (dsrc512 [at] midstatesd [dot] net)

News media reports that truss collapsed under a moving train night of 1/27/22. Eastbound locomotives and approximately twenty loaded grain cars crossed prior to failure of bridge.

This bridge has become a favorite of mine to photograph, it is close to my son-in-law and daughters' property. Their son who is in the USMC has admired this bridge since he was old enough to fish from it. I am gathering as much information and pictures about it to put together a book filled with the 4 seasons of pictures of the bridge as a Christmas gift. This bridge brings memories for so many.

I found a builder on this bridge and the identical bridge at Hudson, SD: Lakeside Bridge & Steel Company. Before today, I had never heard of them. This particular pony truss design had stumped me for years-only one bridge had a plaque, which listed American Bridge Company.

However, bridges such as:

http://bridgehunter.com/mn/steele/medford-railroad/

http://bridgehunter.com/ia/clayton/bh51454/

http://bridgehunter.com/ia/pottawattamie/bh53681/

seem to all be missing plaques (or the plaque is well hidden), possibly suggesting further work by Lakeside for the Milwaukee Road. I would assume the 1932 spans near Neola, Iowa also used Lakeside, but I will work on confirming the other spans with unknown dates.

Posted October 12, 2021, by Nathan Holth (webmaster [at] historicbridges [dot] org)

This historical advertisement in the upper left corner indicates that the spans of this bridge were made available for reuse.

I had a chance to visit this bridge this weekend. Although it needs a new coat of paint, its a great reuse of a historic bridge. During my visit, there were dozens of people walking the bridge, and its clearly a favorite spot of the community. Definitely one of my favorites.

Horse Creek Bridge (South Dakota)
Posted September 16, 2021, by Nathan Holth (webmaster [at] historicbridges [dot] org)

Good work finding the new location! The bridge is a unique design of Canton Bridge Company. Lichtenstein/Transystems refers to them as inverted kingposts in historic bridge inventories. I think of them as a hybrid of lattice girder and inverted kingpost technologies.

Posted September 15, 2021, by Roger Deschner (rogerdeschner [at] gmail [dot] com)

Yup - you did it right here. Add the new location as a new entry, linked by "Parts reused in/from".

I found this photo on the NRHP nomination form, and WOW! I've never seen anything quite like this bridge. It's a smashup of several bridge types, perhaps even a lenticular truss.

Interesting that this was this bridge's second relocation in 2002, having been moved to this site in c. 1972. The substructure is probably from 1972. I wonder where it was before 1972?

Now I want to pretend I golf and go to the golf club to see this thing in its new location.

Still listed on the NR as well... Of course that doesn't always guarantee that a bridge is still extant.

It sounds like money was awarded for the replacement of this bridge..It sounds like a new structure will either be built in 2021 or 2022. This bridge appears to be built out of secondhand railroad parts, so it'll be a shame to lose another one of those.

Posted September 23, 2020, by Nick Schmiedeler (nick [at] nickschmiedeler [dot] com)

Isolated spot on dead-end Capa Rd. into a valley to the east, there is an ancient wooden road bridge still half-there between this bridge and current Capa Rd.

I loved my time out in this area. The stretch between Pierre and Midland was so incredibly desolate, it seemed there was nothing and nobody (except for the old bridges). I dont think I saw a single person or occupied building in that entire stretch. There are a few more of the old trusses out here I would love to get to as well.

Posted September 20, 2020, by Gary Luehr (gluehr63 [at] aol [dot] com)

If you look at historic aerial photographs available online back to 1948 it appears that the bridge is indeed intact and that the river substantially changed course after 1991.

Beauty. Visited yesterday on sad, desolate Capa Road, it basically dead ends to east into the valley - sits few dozen yards from 1885 lattice truss RR treasure John first photographed years ago.

As of the latest imagery it's still sitting pretty!

Posted September 20, 2020, by John Marvig (marvigj27 [at] gmail [dot] com)

Data sheets for this bridge suggest it was converted to road as a WPA project in the 1930s:

http://loc.gov/pictures/item/sd0053/

I don't believe that this came from the parallel railroad bridge however. There is not a single known Quadrangular truss of any sort along the Milwaukee Road, who built the parallel line. Minnehaha County had two other railroads that were known to build such bridges, including the Rock Island and the Omaha Road. With so many realignments of the Big Sioux River during that era, it would not surprise me if this span came from the Sioux Falls area. Another possibility is the former Rock Island crossing of the Big Sioux near Shindler. Historic aerial imagery shows what appears to be a newish looking deck girder bridge at that location in 1938, although it is far too blurry to tell for sure. Until I can find a 108' truss that makes sense, this one may remain a mystery for a long time.

It would be excellent to see this one, which is still stored near Dell Rapids, get reused somewhere. As I understand, they originally wanted to, but the price tag was too high when they were planning it in the late 90s.

Posted September 19, 2020, by Anonymous

Visited today - by accident, sort of dead end roads going east but was more into getting pix of road bridge next to it - didn't realize these were a few dozen yards apart - interesting spot, love the ornate flower cutouts at top of RR bridge - also, both east and west ends are skewed, another interesting characteristic

Posted September 17, 2020, by John Marvig (marvigj27 [at] gmail [dot] com)

Reports are that Watco Companies (which owns dozens of short lines across North America) has proposed to buy the Mitchell-Rapid City line from the state of South Dakota. It sounds like this bridge may see trains again sometime soon...

I've written a mystery bridge article because of some questions I found in my research- namely:

1. Why replace the bridge before nominating it on the NRHP and

2. If the bridge is still listed on the NRHP, where is the structure- apart from it being in storage (hopefully)?

These questions can only be answered by the locals for the newspapers aren't helping.

National Register Nomination Form attached. Does not confirm a builder, claims early 20th Century. I agree with Tony, the Warren truss and also the fishbelly floorbeam pony truss look older. According to form, bridge was moved here in 1950.

Looks like an unusual longer-span example of this:

The unique design was marketed by King Bridge Company's Milo A. Adams who later formed his own company in Minneapolis. His works are known to have been built in Iowa and South Dakota.

This rare pinned Warren through truss is likely a good 20 years or more older than the given build date.

The State Historic Preservation Office was notified but has no power to halt such a project.

This bridge collapsed in March and is being replaced with a new bridge.

Posted May 15, 2019, by John Marvig

This one has been bugging me for some time. The truss matches a late 1880s to mid 1890s Lassig design, standard on both the Rock Island and Chicago & North Western/Omaha Road. While both these railroads operated in Minnehaha county, the parallel Milwaukee Road did not use this design at all.

Also, would love to see this truss reused somewhere (ideally somewhere flood safe).

The old bridge was never replaced. Nothing but the approaches there now and road is closed. You can still walk down there. I crossed the old bridge many times as we lived right there. This old bridge is on Corliss Ave. which is still part of the Forestburg roads. The concrete bridge was the crossing on Highway 34 which we used many times when the James was out of its banks.

A Full Throttle Saloon Facebook video posted on August 1 shows the bridges. The Pratt is being placed on supports by two cranes at approximately 12:45 in the video. No deck so far, but it's nice to see that they're still preserving those bridges.

Alas, I'm not into the whole motorcycle thing, but hopefully someone out there gets some good pictures for Bridgehunter.

Clark,

I've found that a lot of railroad bridges from this era have this unique feature. I've oftentimes wondered the exact same thing.

For discussion: This bridge has pins on the counters but a solid riveted lower. Does this count as a pin connected or riveted? Since the major joints seem to be rigid, I opine riveted but whats the consensus?

Field visited this bridge this weekend. The two main truss spans have a Detroit bridge Company plaque from 1897 and covered up 1898 portal cutouts. It appears this span was relocated from Clinton, Iowa
