First of Its Kind

摘要

The centerpiece of the Interstate 95 New Haven Harbor Crossing Corridor Improvement Program―which includes the reconstruction of approximately 7 mi (11 km) of I-95 in New Haven, East Haven, and Branford, Connecticut―is the replacement of the bridge that carries the interstate over New Haven Harbor at the confluence of the Quinnipiac and Mill rivers. This new bridge will be a signature structure for the New Haven area and is intended to live up to the name it will inherit from its predecessor, the Pearl Harbor Memorial Bridge. The design of the new Pearl Harbor Memorial Bridge includes plate girder approaches and a three-span main crossing that will be built as an extradosed prestressed bridge. Two alternative bridge designs are being fully developed for competitive bidding: a concrete extradosed prestressed bridge and a steel composite extradosed bridge. The latter is believed to be the first design of its type in the world.
