Bridge Documentation

This bridge no longer exists!

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

This historic bridge is being replaced and will be demolished by PennDOT when complete!

This bridge was the last Parker truss in Fayette County and also the last state standard plan truss bridge in Fayette County. This was not enough to keep the bridge from being demolished and replaced by PennDOT, however. The bridge's historic significance as a rare surviving example of an earlier state standard plan truss in Pennsylvania was not acknowledged by the historic bridge inventory. Few examples of this earlier standard plan remain anywhere in Pennsylvania.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The 156' long and 24' wide riveted Parker thru truss bridge built in 1930 is supported on concrete abutments with wingwalls. The trusses are traditionally composed with built up box section for the upper chords and end posts. The web members are rolled section, and the lower chords are channels connected by battens. The bridge has no innovative or distinctive details, and its span length is not unusual. It is an example of a state standard design that was used with great frequency in the 1930s. Neither the bridge nor its setting are historically or technologically significant.

Discussion of Surrounding Area

The bridge carries a 2 lane road over a stream in a sparsely developed, forested setting.

Bridge Considered Historic By Survey: No
