The project involves replacing the historic Pratt Through Truss bridge with a 98’-6” P/S concrete I-beam bridge. The former structure was in serious condition and had been closed to both pedestrian and vehicular traffic for an extended period. An analysis by Keller Engineers and PennDOT determined it could not be rehabilitated; therefore, a new bridge was needed.
During design of the new bridge, the north abutment of the Pratt Through Truss bridge failed, endangering the remaining portion of the structure. An emergency contract was issued for the culturally sensitive removal and storage of the existing truss until a new owner can be found.
Due to the historic nature of the Pratt Through Truss bridge the new bridge, when stained, will appear to be made from mortared stone, and alternate railings across the bridge will have a more natural look. Overall, the project has a total length of 575’ which includes roadway and drainage improvements to both bridge approaches.
