Bridge Documentation

View Archived National Bridge Inventory Report - Has Additional Details and Evaluation

This bridge has an unusual shape and appearance due to the configuration of its panels. If it were a Pratt, it would be a Camelback truss with five slopes. The bridge is also unusual because its connections are bolted, rather than riveted as was more common at the time this bridge was built.

Information and Findings From DHPA Historic Bridge Survey

Statement of Significance

Unusual as a form of the Warren pony, this bridge is rare for the parallel elements of the chords and atypical for the use of bolts and the integration of the verticals with the sway braces. The structure retains its original members, including the latticed guardrails. At 18', the panels of this bridge are tied for the widest on a Warren polygonal chord pony.

Architectural Description

The designers of this single-span Warren pony truss used a polygonal top chord. Parallel with the lower chord in the two most central panels, the top chord slopes once in each direction before meeting the endposts. Seated upon concrete abutments and wingwalls, the largely-bolted structure extends 90' in five panels. Its all-interior verticals and external sway braces are combined into a single member, using pairs of angles riveted together with stay plates. The diagonals are manufactured from a pair of angles (lighter ones toward midspan) riveted together with stay plates. The I floor beams are attached to gussets at the lower chord and carry the 14'9" concrete deck.

Bridge Considered Historic By Survey: Yes
