The Commodore Barry Bridge was designed in the late 1960's, built in the early 1970's and opened to traffic in 1974. The bridge roadway is 60'-0" wide, and carries Route 322 across the Delaware River, connecting the City of Chester in Delaware County, Pennsylvania with the town of Bridgeport in Gloucester County, New Jersey. The main bridge consists of two 1,233-foot cantilevered through trusses and an 822-foot suspended through truss (total main span length of 3,228 feet). Main approach spans consist of 63 simple spans of steel stringers and 11 simple deck truss span. The total length of the bridge from centerline to centerline of abutments is 13,910 feet. The steel superstructure supports an 8-inch thick composite reinforced concrete deck slab.

The suspended span of the Commodore Barry Bridge main through truss is supported by non-redundant, fracture-critical pin and hanger elements. Modjeski and Masters, Inc. designed and provided construction inspection services for an auxiliary support system. The system provides a redundant load path for the pin and hanger elements such that in the unlikely event that a pin and hanger element should fail, catastrophic failure of the structure will be prevented.
