As part of New York City’s first major bridge crossing since 1964, the $318-million second phase of the Kosciuszko Bridge was completed four years ahead of schedule and on budget, says its team.
In what a Skanska USA-led team says is the first-ever “energetic felling” of a New York City bridge and the city’s largest such demolition of any kind, 25,290 tons of steel remaining on the 78-year-old Kosciuszco Bridge, over Newtown Creek, were brought down on Oct. 1 using 944 small charges, detonated on bridge trusses.
A 1.1-mile bridge carrying 160,000 vehicles per day on the Brooklyn-Queens Expressway through an industrial district—and over a long-polluted waterway—might not be the first place to look for green design and construction approaches.
