S-32 (BUMGARDNER DRIVE) Bridge

Bridge Description

The main span of the 142'-long bridge is a 100'-long riveted Warren pony truss with polygonal upper chords. The bridge is supported on 2-column concrete bents for the main span and steel H-pile and concrete cap beam bents for the approach spans. The truss lines are composed of built up members, including the verticals. The floorbeams and stringers are rolled section, and a corrugated steel deck that was placed in 1994. The 3 approach spans, which date to 1955, are the state highway department's standard maintenance slabs. The bridge was rehabilitated in 1994.

Significance

The 1921 riveted pony truss span was fabricated in 1921 for the state highway department and originally located on a state highway over Shaws Creek in Aiken County. It was salvaged and relocated here in 1955. Although not selected by the 1981 metal truss survey, the bridge is one of the oldest pony truss highway bridges surviving in the state, and the earliest known surviving pony truss bridge designed by the state highway department as part of its initial campaign to improve state highways. The design was a state standard that was reused in many locations as part of the department’s efforts to improve its roads during the late 1910s and 1920s. The bridge has been included as a contributing resource to the National Register-listed Tamassee DAR School Historic District.
