Sans Bois Creek Bridge

Photos 

While it is not obvious from the photos, this bridge has a new deck, and huge I-beams underneath, so the truss does not carry all the weight.

Sans Bois Creek Bridge
Posted February 9, 2019, by Carroll Messer (cj [dot] messer [at] att [dot] net)

I agree with Gene McCluney, regarding the location of the Beale Wagon Road iron bridge across the Sans Bois in 1859. My research indicates that this bridge was the fourth of six (from Ft. Smith) Whipple patent cast and wrought iron arch truss (a bowstring) bridges built for the federal government by A. & P. Roberts, Philadelphia, PA in 1859-60. It had a main span of 100-feet. It was demolished late in the Civil War. Its remains are inundated by Robert S. Kerr Reservoir.

4. Sans Bois Creek, 0.6 miles northwest of Iron Bridge, Haskell Co. OK., (100 ft. span), [ 35 14.54 N, 94 58.02 W ], T9N, R22E, Sec. 22;

There are some historians that are saying that this was the location of the Beale Road Iron bridge over the Sans Bois. Circa 1860. This is incorrect. The Beale Road Iron Bridge (one of 6 erected in Eastern Oklahoma in 1859-1860, was located much closer (about 8 miles further east on the Sans Bois) to the town of Iron Bridge, Oklahoma. The true site of the Beale bridge is now inundated due to the formation of a lake, and is not really visible.

Obviously the bridge depicted in my photographs is circa 1910, and has the construction techniques correct for that period, including the lally column supports. I don't think anyone could say that this is an 1860 Iron bridge, by any stretch.
