KCI provided environmental planning, permitting and engineering design services for a single-span concrete box beam bridge, slightly east of the original alignment, to replace the bridge carrying SR 3061 over Tulpehocken Creek. Known locally as the S-Bridge, the three-span stone arch bridge was a state owned structure on a township road (T-503 – William Penn Boulevard) located in Marion Township, Berks County, between the towns of Stouchsburg and Womelsdorf. The bridge was closed to traffic in May 2001 as the result of existing structural deficiencies, including structural cracks through the arch rings in two of the three spans.
KCI performed a rehabilitation feasibility study, including an evaluation from an independent third party expert in the rehabilitation of stone arch bridges. The study results indicated that rehabilitation would not meet current geometric and load capacity standards.
Our team of public involvement specialists developed a brochure that documents the history of the Tulpehocken Creek Historic District and the S-Bridge. This type of documentation preserves the rich history that stone arch bridges have within Pennsylvania and the engineering profession.
Project improvements to the roadway included widening of T-509 (Sheridan Road) at the intersection with T-503 just north of the bridge to improve turning movements for emergency service vehicles and sight distance. Because the stone arch bridge was individually listed in the National Register of Historic Places (NRHP) and was a contributing element in the NRHP-listed Tulpehocken Creek Historic District, the design of the replacement bridge incorporated architectural surface treatments on the abutments, wingwalls, and outside faces of the parapets to reflect the historic setting and character of the area. As a mitigation measure for the replacement of the bridge, a brochure was prepared to document the history of the Tulpehocken Creek Settlement Area. The replacement of the Tulpehocken Creek Bridge restored safe travel through this rural agricultural area following a decade-long bridge closure.
