Golden Gate Bridge
The rust-coloured towers, graceful suspension and supportive cables of the Golden Gate Bridge make this famous symbol of San Francisco the most photographed bridge in the world, and visible from almost any high point in the city, although it is often shrouded in rolling fog. Spanning the two-mile (3km) mouth of the bay, it was the longest suspension bridge in the world at the time of its completion in 1937 and was built to withstand winds of more than 100 mph (161km per hour). During high winds it can sway up to 27 feet (8m) in each direction. One of the great engineering accomplishments of the 20th century, the bridge claims to have used enough wire in its construction to stretch around the earth several times. Walking across the bridge, under the towers that loom 65 storeys above the water, is one of the best ways to experience the immensity of the structure and affords beautiful views of the San Francisco skyline, the bay and its islands. Golden Gate Bridge has a grisly side, however, as it is also a favourite with the suicidal and the sidewalks are dotted with crisis-counselling phones as a sobering reminder.
