This bridge replaced the original 1,300 m (0.8 mi) span which opened on January 2, 1958. The old bridge had a girder and floorbeam design where steel beams supported a concrete bridge deck that 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.
