The Pearl Harbor Memorial Bridge, more commonly referred to as the Q Bridge (the "Q" referring to "Quinnipiac") by locals, is a partially completed extradosed bridge that carries Interstate 95 (Connecticut Turnpike) over the mouth of the Quinnipiac River in New Haven, in the U.S. state of Connecticut. Currently, the northbound span of the new extradosed bridge carries both northbound and southbound traffic, while the original girder-and-floorbeam bridge that opened in 1958, is demolished and the new southbound span is built in its place. The original 1,300 m (0.8 mi) 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.
