Here's the plan. We counted blocks in preparation for ordering. Very excited to do a simple job where it was affordable and will be an asset to the City of Rosebud.
Great to hear it's been properly done, it's difficult to see what's there in the pics. Kudos to all of you involved it's a beautiful project and piece of history.
Believe me I thought the same thing for a long time, was it supported on the first verticals, and how could that be! We will take lots of pictures though, and any repairs that might be required when we can visually inspect all of the shoes and lower chord will be made.
As Julie mentions, the lower chord is a tension element. In other words, bowstrings (although usually called truss bridges) have a great deal in common with tied arch bridges. Sometimes that are called "arch/truss" bridges as a result. A failed (ie cut) lower chord would likely produce clear visual evidence even to non-engineers. As can be clearly seen in the photos, the bowstring retains its shape and form.
That said, there have been a number of people who have misunderstood the condition of this bridge (usually based on quick judgements using photos and not a site visit) and so I look forward to seeing this bridge project completed.
Engineered by our PE on the team. We are putting concrete locking blocks under.
Contracts mean all those details must be covered. Workin' Bridges, BACH Steel and SGI would not be in the business of preserving bridges without attention, these are bridges. We take it very seriously
Look more closely, it's in tension.
It just is buried in the dirt a little bit. Yes to engineered.
Holy Cow. Did they simply cut off the outer bottom chord panels? If so, unless an engineer somewhere analyzed and approved it, I predict it will fall if ever loaded... Someone needs to check into it for the sake of public safety.
The contracts are signed and this bridge's future is a lift. The BACH Steel Gang will head down to Texas this spring. The Parks Department got a grant and help from EDC of Rosebud to fund this project. I enclose some of the history they provided on where this bridge came from and when.
What started as a bridge hunt and a follow up, ends with a relatively easy fix, if you're Nels, Derek, Lee, Brock, Andy and the rest of the gang.
The parks board will save this bridge according to Tiffani Murray of Rosebud. How cool. They even did the research and found out where the bridge has come from, a neighboring ranch. They did diligence on the cost of new and didn't realize that this one could be pulled out if the dirt.
I loved this little bridge and was happy to go see and photograph on my Texas Bridgehuntin' trip. I contacted the City of Rosebud to see how we could help them install this bridge correctly. They were very interested to collaborate and we are generating a list including Texas Historic Commission, Falls County, Preservation Rosebud and other interested parties to put together a "Workin' Week in Rosebud, Texas. Jim Schiffer, PE, SGI and Nels Raynor of BACH Steel, the Workin' Bridges team will lead the efforts." The city administrator Keith Whitfield was very interested, contacting the city council and Preservation Rosebud. The inquiries are going out and we are putting together a Scope of Work and Estimate to supply more details.
Our goal is to get four or so, young or old, men or women, to be part of the paid apprentice crew to work with Nels and his team, sometime next year. Still figuring out what qualifications one would need to apply. Most importantly an interest and desire to know how to work with these historic bridges.
The Scope will include: repairing of repairs to "in kind" engineered restoration that we specialize in, building block abutments to get this thing off the ground, heat straightening and replacing nuts and washers with historic hillside washers and showcase maintenance plans that mostly include washing the iron and keeping the deck sealed.
And a plaque. this bridge needs a plaque.
Thinking big it would be nice to work on the other extant bowstring at the same time, but that one is still in use. It does need some work though so we have called the Commissioner in charge of that road.
Anyone that would like to join this effort, figure out how to fund the restoration and workin' week is invited to get in touch. Please share, we don't want anyone feeling left out of this good work.
This is a great example of how NOT to install a historic bowstring truss.
Looks like another King span from the 1870-1880 era.
Unfortunately, it looks like when they moved it here they cut off the outer panels of the lower chord to make it fit the smaller stream.
According to the website--http://www.texasescapes.com/TexasBridges/Rosebud-Texas-Carne..., the bridge's builder, date, and practically all other information relating to this bridge are a mystery. Anyone knowing anything about this bridge please leave a comment.
