Built in 1946, this 210-foot combination K-Parker truss and a 100-foot Parker pony approach span is located just east of Chouteau on an old alignment of OK 33. Records show that this bridge was built by Amis Construction Co.

Above and below, these markings were found stamped into the bridge in several locations. They were apparently to aid workers in the assembly of the bridge.
Above and below, two views of the unusual 7 panel portal. Most portal of this type were 6 panels.
