GEORGE WASHINGTON BRIDGE

GEORGE WASHINGTON BRIDGE. Spanning the Hudson River between Fort Lee, New Jersey, and 178th Street in Manhattan, the George Washington Bridge was designed by Othmar H. Ammann and constructed by the Port Authority (now Port Authority of New York and New Jersey). It was completed in October 1931, at a cost of $59 million. With a center span of 3,500 feet, twice as long as any bridge span constructed to that date, it became a symbol of the art and craft of the civil engineering profession. Between anchorages, the total length is 4,760 feet; and the deck is suspended from cables composed of galvanized steel wire, with each wire at 0. 196 inches in diameter and the total length of wire at 105,000 miles. A second deck, also designed by Ammann, opened

in 1962; the top level has eight lanes, and the bottom level six. The bridge towers are made of unadorned steel and rise 604 feet above the water; clearance to the Hudson River at mid-span is 212 feet. The bridge carries traffic from New England, Westchester County, New York, and New York City to connecting highways in New Jersey and from there across the nation. Typical eastbound (to New York) weekday traffic in 2000 was 153,000 vehicles and eastbound annual traffic, 54 million vehicles.

George Washington Bridge vehicular suspension bridge across the Hudson River, between Manhattan borough of New York City and Fort Lee, N.J.; constructed 1927–31. It is one of the longest suspension bridges in the world. Its main span is 3,500 ft (1,067 m) long and 250 ft (76 m) above the water. Cass Gilbert was the consulting architect, and O. H. Ammann was in general charge of the planning and construction. In 1962 a lower deck of six lanes was completed.
