Project Role and Scope of Work

The scope of work included coordinating inspections and developing repair schemes for 15 bridges ranging from the Garden State Parkway (GSP) northbound over Squankum Road (MP 95.4), a single span steel stringer superstructure, to the GSP southbound over Drag Channel (MP 28.5), a 19- span pre-stressed beam superstructure with concrete pier caps atop timber piles. In addition, IH performed a pile evaluation study for seven bridges.
