Replacement of the Pearl Harbor Memorial Bridge (Q-Bridge)

June 7th, 2011 – Construction Site Meeting

Join us for a construction site tour of the replacement of the Pearl Harbor Memorial Bridge.  A presentation discussing the bridge replacement will be followed by a site tour which will show current construction activities mostly of which are superstructure related.


Project Description:
The I-95 New Haven Harbor Crossing Corridor Improvement Program is one of the largest transportation improvement initiatives ever undertaken by the Connecticut Department of Transportation (ConnDOT).  The program includes operational, safety and capacity improvements to 7.2 miles of I-95, transit enhancements including a new Shore Line East commuter rail station at State Street in New Haven and construction of a new signature, ten-lane bridge.
Replacement of the Pearl Harbor Memorial Bridge (known locally as the Q-Bridge):  At the confluence of the Quinnipiac and Mill Rivers, the existing six-lane bridge over New Haven Harbor suffers from several structural deficiencies and can no longer accommodate today’s high traffic volumes. When it was built in 1958 as part of the 206-km (129-mile) -long Connecticut Turnpike, it was the largest bridge along the turnpike and included the longest plate girder span in the U.S. The new ten-lane replacement bridge will also be a first—the first extradosed bridge constructed in the U.S.
An extradosed bridge is a hybrid between a cable-stayed and a box-girder structure. Similar in appearance to a cable-stayed bridge, but with shorter towers, the extradosed bridge's structural performance is similar to that of a post-tensioned bridge. The main difference to a post-tensioned structure is that the cables are located outside the superstructure rather than within it. The towers of an extradosed bridge are typically half the height above the deck compared to the towers of an equivalent cable-stayed bridge.
Since this is a construction site, attendees must provide their own hard hats and wear suitable jobsite footwear.  Attendees are encouraged to bring safety vests if they have them.
