The Golden Gate Bridge
It is a suspension bridge spanning the Golden Gate strait, the one-mile-wide (1.6 km), one-point-seven-mile-long (2.7 km) channel between San Francisco Bay and the Pacific Ocean. The structure links the American city of San Francisco, California – the northern tip of the San Francisco Peninsula – to Marin County, carrying both U.S. Route 101 and California State Route 1 across the strait.
