The Golden Gate Bridge was the longest bridge in the world from 1937 when it was completed until the Verrazano Narrows Bridge was built in New York in 1964. Today， it is still the ninth longest bridge in the world.

For many years before the Golden Gate Bridge was built， the only way to get across San Francisco Bay was by ship. And by the early twentieth century the Bay was crowded because of them. In the 1920s， engineer and bridge-builder Joseph Strauss believed that a bridge should be built across the Golden Gate to solve the problem.

Many groups went against him， each for their own selfish reasons. Besides， the engineering challenge was also huge—the Golden Gate Bridge area often has winds of up to 60 miles per hour， and strong ocean currents （洋流） sweep below the surface. If all that werent enough， it was the middle of the Great Depression， and funds were hard to find.

Strauss didnt give up， and the Golden Gate Bridge history began when San Francisco officials approved （批准） $35 million to build the Golden Gate Bridge. After the artistic design and red color were chosen， construction （建造） work began in 1933. The Golden Gate Bridge project was completed in 1937， an important date in San Francisco history.

Strauss was a pioneer in building safety. The Bay Bridge， which was being built at the same time cost 24 lives while the Golden Gate Bridge cost only 12， a great achievement in a period of time when one man was killed on most construction projects for every million spent.
