Delaware River and Bay Authority Awards Memorial Bridge Protection System

Modjeski and Masters has recently been selected for the Delaware Memorial Bridge Protection System contract with the Delaware River and Bay Authority.

As the prime consultant for this contract, Modjeski and Masters will design a vessel collision protection system for the northbound and southbound structures of the Delaware Memorial Bridge. The firm will design new pier protection cells and replace the channel-side fender system for the tower piers. The existing fender system is original to each of the spans and inadequate to protect the bridge from collisions with modern cargo ships.

The design will protect the Delaware Memorial Bridge from a vessel collision in the range of 156,000 deadweight tonnage, traveling at a speed of approximately seven knots. Modjeski and Masters will adhere to all American Association of State Highway and Transportation Officials Load and Resistance Factor Design specifications for this design.

The project will satisfy a federal mandate to enhance protections for critical bridges around the country. The Delaware Memorial Bridges carries Interstate 295, connecting travelers from New York City to Washington, D.C., and the New Jersey Turnpike. The project is expected to cost $45-46 million.
