NJDOT Rt 46 over Hackensack River Bridge Rehabilitation and Future Cities Student Award Winner Presentations

The project involves a recently completed rehabilitation of the NJDOT bridge located in Little Ferry and Ridgefield Park, Bergen County, New Jersey. The bridge is 1,550 ft long with 16 concrete encased approach spans and a double leaf steel bascule span. There are 2 EB and 2 WB lanes with no shoulder and 8 ft sidewalks on both sides. The deck slab was removed and replaced half the bridge at a time while maintaining 2 lanes (1 EB and 1 WB) and one sidewalk for pedestrians. Unique features in the bridge rehab include cast-in-place exodermic bridge deck system used for the deck slab replacement, architectural concrete balustrade replacement to mimic the existing, bascule span steel repairs, concrete encasement removal and construction access, rocker bearing repairs including anchor and girder bolt replacement, seismic retrofits including cable restrainers and concrete shear blocks and the installation of a NY 2-rail along the sidewalk curb line to protect motorists and pedestrians.
