Long Slip Pedestrian Bridge

The 175 foot long Slip Pedestrian Bridge connects Hoboken to Jersey City and is part of the Hudson River Waterfront Walkway - which extends about 15 miles in Hudson County and is intended to connect a system of parks, piers and open space along the Hudson River and Upper New York Bay waterfront from the George Washington Bridge to the Bayonne Bridge. The project included construction of a new steel sheet piling bulkhead with cathodic protection, a relieving platform and the bridge itself.

YU & Associates, Inc. (YU) as a geotechnical subconsultant provided Geotechnical support services during the construction. With the aid of dynamic analyses and testing methods we observed and evaluated the test piles driven at the site, reviewed contractor submittals and provided consulting services related to evolving project design. The deep foundations included 36” outside diameter pre-stressed concrete cylinder piles (pictured) and steel H-piles.
