Arrowhead Trail / Sugar Camp Road Overpass - Structure Replacement
Peters Township, Washington County, PA
Stahl Sheaffer provided engineering services for the replacement of a single span cast-in-place reinforced concrete arch carrying Arrowhead Trail over SR 1004 (Sugar Camp Road) in Peters Township, Washington County. As part of the project, three structure alternatives were investigated during preliminary design. The options included a precast reinforced concrete arch under fill, a single span composite prestressed concrete I-beam bridge on pile supported integral abutments, and a single span prestressed concrete adjacent box beam bridge on cantilever abutments. The selected replacement is a 145'-6" single span structure consisting of three 33/71.5 PA Bulb-Tee Beams on integral abutments. Stahl Sheaffer performed a field survey along with a geotechnical investigation and foundation exploration in order to complete an appropriate design of the new tunnel/bridge. An E&S Control Plan was created to meet DEP’s standards and a PennDOT HOP was obtained. To complete the design process, coordination was required with PennDOT Engineering District 12-0 to obtain Structural Adequacy and Foundation Approval.
