The strait Bridge
may be a bridge spanning the strait, the gap of the metropolis Bay into the Pacific Ocean. As a part of each U.S. Route one zero one and Golden State State Route one, the structure links town of metropolis, on the northern tip of the metropolis earth, to Marin County. it's one in all the foremost internationally recognized symbols of metropolis, California, and therefore the us. it's been declared one in all the trendy Wonders of the planet by the yankee Society of Civil Engineers. The Frommers travel guide considers the strait Bridge "possibly the foremost lovely, definitely the foremost photographed, bridge within the world".[7]

History
Golden Gate with Fort purpose in foreground, c. 1891
Before the bridge was engineered, the sole sensible short route between metropolis and what's currently Marin County was by boat across a part of metropolis Bay. Ferry service began as early as 1820, with often scheduled service starting within the decennary for functions of transporting water to metropolis,The Sausalito Land and Ferry Company service, launched in 1867, eventually became the strait Ferry Company, a Southern Pacific Railroad subsidiary, the most important ferry operation within the world by the late Twenties. Once for railroad passengers and customers solely, Southern Pacific's automobile ferries became terribly profitable and vital to the regional economy.[10] The ferry crossing between the Hyde Street Pier in metropolis and Sausalito in Marin County took about twenty minutes and value US$1.00 per vehicle, a worth later reduced to contend with the new bridge.The trip from the metropolis Ferry Building took twenty seven minutes.
Many needed to
create a bridge to attach metropolis to Marin County. metropolis was the most important yankee town still served primarily by ferry boats. as a result of it didn't have a permanent link with communities round the bay, the city's rate was below the national average. several consultants aforesaid that a bridge couldn’t be engineered across the vi,700 ft (2,042 m) strait. It had robust, whirling tides and currents, with water 372 linear unit (113 m) deep[13] at the middle of the channel, and frequent robust winds. consultants aforesaid that fierce winds and glaring fogs would stop construction and operation
Conception
Although the thought of a bridge spanning the strait wasn't new, the proposal that eventually took hold was created in an exceedingly 1916 metropolis Bulletin article by former engineering student James Wilkins.[14] San Francisco's town Engineer calculable the value at $100 million, impractical for the time, and fielded the question to bridge engineers of whether or not it can be engineered for fewer.[8] One WHO responded, Joseph Strauss, was AN bold however dreamy engineer and author WHO had, for his graduate thesis, designed a 55-mile (89 km) long railroad bridge across the strait.[15] At the time, Strauss had completed some four hundred drawbridges—most of that were inland—and nothing on the size of the new project.[3] Strauss's initial drawings[14] were for a vast cantilever on all sides of the strait, connected by a central suspension section, that Strauss secure can be engineered for $17 million.
Local authorities
in agreement to proceed solely on the peace of mind that Strauss alter the planning and settle for input from many consulting project consultants.[citation needed] A suspension-bridge style was thought of the foremost sensible, owing to recent advances in science.
Strauss spent over a decade percussion up support in Northern Golden State.[16] The bridge visaged opposition – together with legal proceeding – from several sources. The Department of War was involved that the bridge would interfere with ship traffic; the navy feared that a ship collision or sabotage to the bridge might block the doorway to at least one of its main harbors. Unions demanded guarantees that native staff would be favored for construction jobs. Southern Pacific Railroad, one in all the foremost powerful business interests in Golden State, opposed the bridge as competition to its ferry fleet and filed a legal proceeding against the project, resulting in a mass boycott of the ferry service.[8] In might 1924, commissioned military officer Herbert Deakyne command the second hearing on the Bridge on behalf of the Secretary of War in an exceedingly request to use federal land for construction. Deakyne, on behalf of the Secretary of War, approved the transfer of land required for the bridge structure and leading roads to the "Bridging the strait Association" and each metropolis County and Marin County, unfinished any bridge plans by Strauss.[17] Another ally was the fledgling industry, that supported the event of roads and bridges to extend demand for vehicles.
