2014 Walt Whitman Bridge Biennial Inspection

New Jersey/Pennsylvania<br style='line-height:2px'>Delaware River Port Authority

HAKS performed the 2014 general bridge inspection of the Walt Whitman Bridge, which connects New Jersey with Pennsylvania, for the Delaware River Port Authority. This suspended signature structure was opened to traffic in 1957 and carries seven lanes of I-76 over the Delaware River. The bridge consists of a 2,000-foot suspension span and two 770-foot side spans. The anchorages are three continuous spans with multi-beam configuration, while the approach spans consist of various structural configurations such as deck trusses, girder-floorbeam-stringer, and multi-beams. 

The inspection focused on accessing critical members and areas of the bridge and bridge approaches for hands-on inspection, including the main cables, suspended ropes, stiffening trusses, floor systems, deck, towers, anchorages, piers, and abutments. The project included inspection of sign gantries, the toll booth access tunnel, noise barriers, high-mast lighting, and ground-level standpipe and miscellaneous electrical accessories.

Extensive MPT was required to inspect above-deck elements and street-level sections of the approaches. Inspections over this major waterway and active railroads required coordination with the U.S. Coast Guard and railroad owners.
