Bridge Documentation

This bridge was built to cross a new realignment of the Patoka River that had been completed. The effort to create this new straight river channel was not entirely successful, and water continued to flow through the old river at times. The old river bridge, also historic, remains in place a short distance south of this bridge.

Statement of Significance

Resting atop concrete abutments and wingwalls, this through Camelback follows a popular pattern for a short version of this truss. Laced channels divide the 144' span into eight panels (three central; two for each side section; one under each endpost). Central panels have crossed diagonals; side panels angle diagonals only toward span center from the top chord. All diagonals and the lower chord on this truss are fabricated from angles and stay plates; there are no eyebars or turnbuckles. I floor-beams are bolted to gussets and the verticals above the lower chord. The concrete deck provides a 15'7" roadway and 18 feet of vertical clearance. This truss retains its original members and is one of five extant bolted Camelbacks. References Ohio Valley Engineers, Bridge Inspection Survey and Report: Pike County (Evansville, 1974).
