Amman & Whitney, a Louis Berger company, has been awarded the 2012 Biennial Bridge Inspection contract for the Commodore Barry Bridge from the Delaware River Port Authority (DRPA) for its transporation division.
The five-lane bridge, which is a cantilevered span, connects Chester, PA to Bridgeport, NJ and measures approximately 2.6 miles long including its approaches. To allow ships from the port of Philadelphia-Camden to pass underneath, the bridge was constructed with a mid-span clearance of 192 feet. Completed in 1974 at a cost of $115 million, the Commodore Barry Bridge brought more than two centuries of continuous ferry service between PA and NJ to an end. The bridge is named after the American Revolutionary War hero and Philadelphia resident John Barry.
In recent years, condition inspection work has been a large component of Ammann & Whitney’s practice. Our previous DRPA assignments include the 2006 and 2004 inspections of the Commodore Barry Bridge, the 2008 inspection of the Betsy Ross Bridge, the 2002 and 2000 inspections of the Walt Whitman Bridge and the 1996 inspection of the Benjamin Franklin Bridge. These four toll bridges connect the metropolitan Philadelphia region with southern New Jersey. As can be seen from this chronology, Ammann & Whitney has had a near continuous involvement in the inspection of the DRPA’s long span bridges since 1996. We recently completed a design to dehumidify the Walt Whitman Bridge Anchorages and are awaiting the start of construction. We are also currently working on a design of the resurfacing of the Betsy Ross Bridge roadways.
