This 2.12 mile steel box girder bridge, opened in 1969, connects San Diego with the Coronado isthmus across San Diego Bay.  It has a vertical clearance of approximately 175 to approximately 195 feet, and a height of over 200 feet.  The California Department of Transportation notes it was built at a cost of $47.6 million.  With three span continuous orthotropic box girders, it has the longest continuous box girder in the world and is supported by thirty towers. "Orthotropic" design means vehicles travel on the bridge structure itself and not on a separate deck.  Its blue color was meant to mesh with the colors of the water and sky.
