Greasy Bend Road Washita River Bridge West, Johnston Co.

Greasy Bend Road, in Johnston county crosses the Washita river twice, once near its east end and once near its west end.

The nine-panel long K-truss spans were built in 1954. The Quadrangular Warren through truss was  built much earlier, in 1911.  The Warren span was moved here to complete this three span bridge, having been one of the 15 spans that made up the Lexington-Purcell toll bridge. There are two additional quadrangular Warrens from this toll bridge in Le Flore County.

Let's start out with a portal and deck view of this very unique bridge. The deck is asphalt over wood on all three spans.

The extremely sandy Washita River made bottom and side views of this bridge easy to obtain. The floor beams of the Warren span are slung under the lower chord. The lower chord is made of angle in the Warren span, and H-section (actually called a "W" beam) in the K-truss. This has been the only time I have seen as one-lane K-truss bridge in Oklahoma.


Now looking straight through the three spans. The curved-top K-truss spans are about 35' longer than the flat-topped Warren.


In this side view, the Quadrangular Warren is hard to distinguish against the trees, but the profile of the K-truss spans is very distinguishable. The Oklahoma design 9-panel K-truss is almost as rare as the 12-panel, 240' design. The Quadrangular Warren is also 9 panels long
