American civil engineer Joseph B. Strauss (1870 -193
was chief engineer and designer of the bridge. He was assisted in the design by Charles Ellis and Leon Moissieff. An engineering masterpiece that opened to traffic in May 1937, this suspension bridge spans San Francisco Bay, and links San Francisco with Marin County, California. (A suspension bridge is one in which the roadway hangs from steel cables that are attached to two or more towers.) It has a central span (length between towers) of 4,200 feet (1,280 meters), with towers rising 746 feet (2,274 meters) above the water. The Golden Gate Bridge was the world's longest bridge until the construction of the Verrazano-Narrows Bridge in New York City in 1964.
