PROJECT DESCRIPTION
The Gerritsen Inlet Bridge is one of the four major bridges on the Shore (Belt) Parkway System that connects Brooklyn to Queens/Long Island to the east and Staten Island/Manhattan to the west. It was built in 1940 and carries about 70,000 vehicles per day.
CCA was awarded the replacement project in December 2012 as part of the $700 million Shore (Belt) Parkway Rehabilitation Program. The project calls for clearing more than 14 acres of wooded land and tearing the existing bridge down to its foundation and pile level to make way for the new bridge. The reconstruction includes building a three-span superstructure that is 150 meters long and 37 meters wide, new piers and abutments on piles, new approach roadways, new drainage system, new street and navigation light, new bicycle path and other safety improvements.
The existing roadway profile will be raised by 4 meters to provide a better stopping sight distance, which will require importing and placing 180,000 cubic meters of fill material in one of the most environmentally sensitive wetlands.
The project will be completed in three major stages, and include a pre-stage (pre-stage I) and a post-stage (stage IV). Each stage has a very elaborate Maintenance and Protection of Traffic (MPT) scheme to minimize impact to the traveling public.
