Grays Ferry Avenue Bridge Rehabilitation

Promo Icon 2 Updated

Looking to repair weathering steel box-girder plate caps which were uniquely welded, PennDOT enlisted the expertise of Modjeski and Masters for guidance on how to repair the caps. In addition, M&M was also tasked with developing a bridge rehabilitation solution that considered the needs of stakeholders in the city of Philadelphia. 

M&M developed an efficient rehabilitation solution for the bridge which resulted in only needing to repair a few of the unique steel pier caps instead of unnecessary retrofits previously recommended--potentially saving the client millions of dollars. Throughout the project, M&M also guided the client through a rigorous stakeholder coordination process, balancing the needs of all stakeholders while also keeping safety, economics, and good engineering principles front of mind.
