Rehabilitation of the Frankford Avenue Bridge, the Oldest Continuously Used Roadway Bridge in the United States

presented by Margaret K. Sherman, P.E and Michael J. Cuddy, P.E.

The Frankford Avenue Bridge, located in the Holmesburg neighborhood of Philadelphia, is the oldest continuously used roadway bridge in the United States. The three span, stone masonry, arch bridge carries a two-lane road with flanking sidewalks over Pennypack Creek. Originally built in 1697 as part of the King’s Highway, the bridge was first paved in 1803 and widened in 1893. Worsening deterioration and collision damage necessitated that the Pennsylvania Department of Transportation Engineering District 6-0 (PennDOT) take steps to repair the damage and preserve this engineering landmark. TranSystems served as designer on the award-winning bridge rehabilitation project, and construction was completed in September 2018.

Margaret K. Sherman, P.E, “Meg”. is an Assistant Vice President with TranSystems. As the Office Director of the Philadelphia office, Meg is responsible for the company’s work through southeastern Pennsylvania. She has been with the firm for almost 17 years and has managed and contributed to many bridge design, rehabilitation, and inspection projects, particularly those involving historic bridges. A graduate of The University of Texas in Austin and Lehigh University, she is a registered professional engineer.

Michael J. Cuddy, P.E. is a Principal/Senior Vice President with TranSystems and Entity Manager responsible for the firm’s transportation work throughout Pennsylvania.  He has been with the firm for 38 years and is responsible for many of its major bridge design, rehabilitation and inspection programs, particularly those involving historic bridges and complex structural systems.  He has been the project manager on such notable rehabilitation projects as the Wheeling Suspension Bridge, the oldest existing suspension bridge with a span greater than 1,000' and the University Avenue bascule bridge, designed by noted Philadelphia architect Philip Cret.  A graduate of The University of Pennsylvania, he is a registered professional engineer and is noted for his innovative and practical approach to the evaluation and rehabilitation of historic bridges.
