At the time, Strauss had completed some 400 drawbridges-most of which were inland-and nothing on the scale of the new project. One who responded, Joseph Strauss, was an ambitious engineer and poet who had, for his graduate thesis, designed a 55-mile-long (89 km) railroad bridge across the Bering Strait. He asked bridge engineers whether it could be built for less. San Francisco's City Engineer estimated the cost at $100 million (equivalent to $2.7 billion today), and impractical for the time. 1891Īlthough the idea of a bridge spanning the Golden Gate was not new, the proposal that eventually took hold was made in a 1916 San Francisco Bulletin article by former engineering student James Wilkins. Conception Golden Gate with Fort Point in foreground, c. Experts said that ferocious winds and blinding fogs would prevent construction and operation. Many experts said that a bridge could not be built across the 6,700-foot (2,000-metre) strait, which had strong, swirling tides and currents, with water 372 ft (113 m) deep at the center of the channel, and frequent strong winds. Because it did not have a permanent link with communities around the bay, the city's growth rate was below the national average. San Francisco was the largest American city still served primarily by ferry boats. Many wanted to build a bridge to connect San Francisco to Marin County.

The trip from the San Francisco Ferry Building took 27 minutes. The ferry crossing between the Hyde Street Pier in San Francisco and Sausalito Ferry Terminal in Marin County took approximately 20 minutes and cost $1.00 per vehicle prior to 1937, when the price was reduced to compete with the new bridge. Once for railroad passengers and customers only, Southern Pacific's automobile ferries became very profitable and important to the regional economy. In 1920, the service was taken over by the Golden Gate Ferry Company, which merged in 1929 with the ferry system of the Southern Pacific Railroad, becoming the Southern Pacific-Golden Gate Ferries, Ltd., the largest ferry operation in the world. In 1867, the Sausalito Land and Ferry Company opened. A ferry service began as early as 1820, with a regularly scheduled service beginning in the 1840s for the purpose of transporting water to San Francisco. History Ferry service įurther information: Ferries of San Francisco Bayīefore the bridge was built, the only practical short route between San Francisco and what is now Marin County was by boat across a section of San Francisco Bay. Its main span is 4,200 feet (1,280 m) and its total height is 746 feet (227 m). The Golden Gate Bridge is described in Frommer's travel guide as "possibly the most beautiful, certainly the most photographed, bridge in the world." At the time of its opening in 1937, it was both the longest and the tallest suspension bridge in the world, titles it held until 19 respectively. The bridge opened to the public in 1937 and has undergone various retrofits and other improvement projects in the decades since. Joseph Strauss served as chief engineer for the project, with Leon Moisseiff, Irving Morrow and Charles Ellis making significant contributions to its design. The idea of a fixed link between San Francisco and Marin had gained increasing popularity during the late 19th century, but it was not until the early 20th century that such a link became feasible. Recognized by the American Society of Civil Engineers as one of the Wonders of the Modern World, the bridge is one of the most internationally recognized symbols of San Francisco and California.

It also carries pedestrian and bicycle traffic, and is designated as part of U.S. Route 101 and California State Route 1 across the strait.
