    Bridges are not only the superstars of the engineering world, they influence the development of cultures, environments and lives in more ways than we can count. Bridges shape skylines. Imagine San Francisco without the Golden Gate Bridge, or Manhattan without the Brooklyn Bridge. These structures also shape our lives, aiding commerce, social life and urban development. I have compiled a list of what I think are some of the biggest and best bridges in the world. This is obviously not a complete list, the one's included I feel are recognised world wide.

    The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the opening of the San Francisco Bay onto the Pacific Ocean. As part of both U.S. Route 101 and California State Route 1, it connects the city of San Francisco on the northern tip of the San Francisco Peninsula to Marin County. The Golden Gate Bridge was the longest suspension bridge span in the world when it was completed during the year 1937, and has become an internationally recognized symbol of San Francisco and California. Since its completion, the span length has been surpassed by eight other bridges. It still has the second longest suspension bridge main span in the United States, after the Verrazano-Narrows Bridge in New York City. In 2007, it was ranked fifth on the List of America's Favorite Architecture by the American Institute of Architects.
    Now a little history i dont like history lol Very Happy its boring Smile

    Before 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. Ferry service began as early as 1820, with regularly scheduled service beginning in the 1840s for purposes of transporting water to San Francisco. The Sausalito Land and Ferry Company service, launched in 1867, eventually became the Golden Gate Ferry Company, a Southern Pacific Railroad subsidiary, the largest ferry operation in the world by the late 1920s.[5][6] Once for railroad passengers and customers only, Southern Pacific's automobile ferries became very profitable and important to the regional economy. The ferry crossing between the Hyde Street Pier in San Francisco and Sausalito in Marin County took approximately 20 minutes and cost US$1.00 per vehicle, a price later reduced to compete with the new bridge. The trip from the San Francisco Ferry Building took 27 minutes.

    Many wanted to build a bridge to connect San Francisco to Marin County. San Francisco was the largest American city still served primarily by ferry boats. Because it did not have a permanent link with communities around the bay, the city’s growth rate was below the national average. Many experts said that a bridge couldn’t be built across the 6,700 ft (2,042 m) strait. It had strong, swirling tides and currents, with water 500 ft (150 m) in depth at the center of the channel, and frequent strong winds. Experts said that ferocious winds and blinding fogs would prevent construction and operation.
    Design now Very Happy only then mite123 lol Smile
    Strauss was chief engineer in charge of overall design and construction of the bridge project.[9] However, because he had little understanding or experience with cable-suspension designs,[15] responsibility for much of the engineering and architecture fell on other experts.

    Irving Morrow is creator of AWESOME golden gate bridge.
    All for today lol
