Pearl Harbor Memorial Bridge

The Pearl Harbor Memorial Bridge, more commonly referred to as the Q Bridge by locals, is an extradosed bridge that carries Interstate 95 over the mouth of the Quinnipiac River in New Haven, in the U.S. state of Connecticut. The original 1,300 m span – which opened on January 2, 1958 – was a girder and floorbeam design where steel beams support the concrete bridge deck. The bridge carried three lanes of traffic in each direction with no inside or outside shoulders. The bridge was officially dedicated as the Pearl Harbor Memorial Bridge in 1995 to commemorate the attack on Pearl Harbor.
The old Pearl Harbor Memorial Bridge was replaced by a $554 million 10-lane extradosed bridge; the northbound span of which opened to traffic on June 22, 2012. Southbound traffic was shifted onto the new bridge, sharing the northbound span with northbound traffic until the new southbound span was completed in late 2015. Since the Gibbs Street Bridge in Portland, Oregon was redesigned from an extradosed span to a box girder bridge, the Pearl Harbor Memorial Bridge was the first extradosed bridge completed in the United States when it fully opened in September 2015. The new bridge is the centerpiece of a $2 billion megaproject to reconstruct and widen 13 miles of I-95 between West Haven and Branford, called the I-95 New Haven Harbor Crossing Improvement Program.
