Washington Township, PA

Rock Covered Bridge

LDG provided survey, hydrologic and hydraulic services, bridge design, and structural engineering for the rehabilitation of the Rock covered bridge, a historic burr arch truss structure in Washington Township, Schuylkill County, Pennsylvania. The project’s goal was to improve the safety of the bridge and increase the structural capacity from three tons to 15 tons. The rehabilitation included replacing the existing steel through girders with new steel I-beams, replacing deteriorated timber truss members with new timber members, evaluating the live load capacity of the substructure, and coordinating with PennDOT, District 5, the Schuylkill County Commissioners, and the Pennsylvania Historical and Museum Commission (PHMC).
