The Commodore Schuyler F. Heim Bridge was a vertical-lift bridge in the Port of Los Angeles. Dedicated on January 10, 1948, the bridge allowed State Route 47 (the Terminal Island Freeway) to cross over the Cerritos Channel. Named after Schuyler F. Heim, who was in command of the Naval Air Station on Terminal Island in 1942, the bridge was one of the largest vertical-lift bridges on the West Coast. At the time of its opening, it was the highest in the country with the deck weighing about 820 short tons (740 metric tons). Its towers are 186 feet (57 m) tall above the roadway deck and about 236 feet (72 m) tall when measured from the water level at high water. The bridge was decommissioned on October 12, 2015 and replaced by a new, six-lane fixed-span bridge in order to meet current safety an
