Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The one span, 71'-long, pin connected Pratt pony truss bridge built in 1894 is supported on concrete abutments that date to 1966, the year the bridge was rehabilitated and the flooring system with an open grid deck was placed. The rolled floorbeams are still connected with suspenders. The original railings inside the truss lines have been lost, and plate has been welded to the webs of the upper chords and end of the inclined end posts. The bridge has no innovative or distinctive details as it reflects the standardization of details that occurred after 1890. The altered bridge is not historically and technologically significant. It is the early, complete truss bridges and those with distinctive details that are significant in this region that has over 100 metal truss bridges. Groton Bridge Co. was a prolific regional bridge builder.

Discussion of Surrounding Area
