This bridge was on Warm Springs Rd, not Airport Rd as previously thought. Airport Rd has a Warren pony truss bridge already, and it looks to be original. The building and the fence in the HAER pics are still there and are on the northwest corner of the new concrete bridge. The old bridge is shown in the 1994 satellite view, but the next available view is 2006 and the new bridge is there.


Lost Bowstring pony truss bridge over Big Wind River on Airport Rd. (CR 21)
Fremont County, Wyoming
Replaced by a new bridge
HAER info is sketchy at best, says estimated build year is 1920, it was jerryrigged, and was made from salvaged materials.
HAER info is not really helpful. It says that the bridge is jerryrigged and made from salvaged materials. From the pictures it looks like some form of a bowstring pony truss.
Total length: 74.0 ft.

Funny thing is, these Redneck bridges are still far more interesting than any modern UCEB! HA!!

I call these Redneck Bridges. Find some random junk, make a bridge: Git-R-Done!

According to Wikipedia, it was listed to the National Register of Historic Places in 1985. Of course that doesn't mean it still exists, but there should be a record of it somewhere. It also calls it the ELS Bridge.

#9 on the list


Airport Road Bridge

Very unusual bridge.

Hard to tell for certain if the arches are tubular or if they are composed of channels (sideways) with cover plate on top. The lack of any trussing except for a single vertical with an outrigger might indeed suggest a homemade deal of some kind.

If it is on an airport access road then I doubt it still exists, unless it was relocated elsewhere.

Ok.....just found this bridge searching through the HAER/HABS files. There is no NBI info and this bridge is not previously listed, so its totally an original find. If this bridge still exists that will be awesome, however, I cannot confirm anything using Google Earth because the image is fuzzy and street view cannot make it out. I need help. Also any more info regarding its design, construction, and date would be helpful.
