This historic bridge was demolished and replaced by PennDOT!

This bridge was a good example of a state standard plan pony truss bridge. With a 118 foot span length, this was a relatively long pony truss span as well. Aside from some isolated repairs such as a small welded plate added to the bottom of a vertical member, the bridge retained excellent historic integrity. No modern railings were added to the bridge and the two cantilevered sidewalks retained their original lattice railings. Bridges such as this one were dismissed by Pennsylvania's historic bridge inventory as common. However, as the demolition of this bridge shows, it is not acceptable to write these bridges off as common anymore.

This bridge was the only historic bridge in the small Clymer borough, and now thanks to a replacement project by PennDOT, historic bridge enthusiasts no longer have a reason to visit Clymer, since all traces of bridge heritage and beauty have now been erased.

At the very, very, least, it would have been nice to see this bridge's trusses and railings salvaged and either placed on the replacement bridge as decoration or perhaps placed near the replacement bridge as an interpretive memorial.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The 122'-long, riveted Parker pony truss bridge built in 1934 is supported on concrete abutments with wingwalls. The trusses are traditionally composed with rolled section used for the web members. The cantilevered sidewalks are finished with lattice railings. The bridge has no innovative or distinctive details, and it is an example of a frequently used state standard design. Rolled section for web members dates to the late 1920s. Neither the bridge nor its setting are historically or technologically significant.

Discussion of Surrounding Area

The bridge carries a 2 lane street and sidewalks over a stream on the eastern edge of Clymer Borough. There may be a potential historic district in Clymer, but the bridge is at least one block south of it. Adjacent to the bridge is a concrete block church, a sports field, and vacant lots.

Bridge Considered Historic By Survey: No
