San Diego's Coronado Bridge - The span reaches a maximum height of 200 feet (61m), allowing the U.S. Navy ships which operate out of the nearby Naval Station San Diego to pass underneath it. The two Nimitz class aircraft carriers home-ported in San Diego, the Nimitz and the Reagan, are 201 feet (61 m) high and tie up at Naval Air Station North Island, located between the bay entrance and the bridge. The five-lane bridge features the longest box girder in the world.
