The Admiral Clarey Bridge in Pearl Harbor, Hawaii, combines fixed and floating bridge elements to span more than 4,500 ft (1,372 m) while hovering just above the harbor waters. The bridge, which received an ASCE Outstanding Civil Engineering Achievement Award of Merit, could not overshadow the U.S.S. Arizona Memorial but it also had to accommodate aircraft through carriers that pass the harbor monthly. The bridge is primarily constructed of concrete with fixed sections supported by pile and spread footings. The floating section is 930 ft (283.5 m) long and moves 760 ft (231.6 m) to create a 650 ft (198.1 m) opening. The floating and fixed sections are connected by steel transition spans. Construction included the use of pipeline epoxy coated rebar for all concrete elements.
