Admiral Clarey Bridge

Admiral Clarey Bridge, also known as the Ford Island Bridge, is a pontoon bridge, commonly called a floating concrete drawbridge, providing access to Ford Island, a United States Navy installation situated in the middle of Pearl Harbor. The bridge provides access to Ford Island's historic sites to the public via tour bus and provides access to O'ahu for US military families housed on the island. Before the completion of the bridge, the island's residents were required to use ferry boats operated by Naval personnel that operated on an hourly basis. The bridge is one of only a few floating bridges and its floating moveable span is the largest worldwide. Its namesake, Admiral Bernard A. Clarey, was one of the Navy's most decorated officers.
