US 271 Big Cedar Creek, Pushmataha County

Shown here in its twilight hour, this veteran of highway service was built in 1933 by Altman-Rogers and features a 180-foot riveted K-truss mainspan and two 60-foot steel stringer approaches. All spans feature a 24-foot wide deck, accommodating full width lanes. Above, a view looking through the bridge.

Below, an angled view of the main span from an elevated position. The concrete work on the approaches have all been replaced, and the portal sway bracing and much of the intermediate sway braces have been repaired or replaced. With its 15-foot clearance, the sway braces have been hit many times.

Above, a detail view of the portal frame. You can see the gusset plates where the original portal braces mounted.

Below, in this view of the trusses, you can see where a lot of repairs have been welded in.

 

Above, a side view of the truss, framed by its replacement's substructure. This span is a 9-panel riveted K-truss. Below, a final view of the span.
