Iconic Curve

Unlike other bridges, this bridge is long and curved. The 90-degree curvature was essential to keep it stable at a height of 200 ft.
Why is the Bridge so Tall?
The bridge was built at such a height so that the tallest naval ships could pass below it. As San Diego is a naval port, the channel required the tall bridge to allow passage of ships beneath it.
Its 200 feet clearance level also enables empty oil-fired aircraft carriers to fly under the bridge (if need be).
Why is the Bridge Blue?
The bridge has been painted in a radiant blue shade to blend in with the sky and sea.
A crew is constantly painting the bridge to maintain its color and prevent the ocean breeze from corroding the bridge.
According to a legend, in case this bridge is bombed, its hollow central span (1,880 feet long) or box girder would float on water.
This concrete and steel bridge has been intentionally designed this way so the US Navy could push aside the large floating central piece and still cross the bay.
Truth behind the Legend
Although theoretically, it is possible for the hollow central box to float if it hits the water, according to the main architect of the bridge, Robert Mosher, this legend is baseless.
The 1,880 feet long, hollow center span is connected to both sides of the bridge. A bomb cannot precisely separate an intact center span from its sides.
Any crack will let the water into the center span, causing it to sink. Only if the hollow box fell intact into the water could it float, and this is highly unlikely.
