Golden Gate Bridge

Attracting Over 10 Million Visitors Per Year

Details

For locals, The Golden Gate Bridge (Highway 101 North) provides a vital link between San Francisco and Marin County and is possibly the prettiest morning commute in the world. For over 10 million visitors each year, walking on the bridge is the highlight of their trip to San Francisco. 

History

Named after the Golden Gate Strait that it spans; the Golden Gate Bridge marks the entrance to the San Francisco Bay from the Pacific Ocean.

Joseph B. Strauss was Chief Engineer on the bridge. At a cost of $35 million, the 1.2-mile bridge took more than four years to build. Eleven men lost their lives during construction (a memorial plaque at the southern entrance to the west sidewalk commemorates the men who were killed). A net suspended under the bridge during construction, from end to end, saved the lives of 19 men who became known as the "Half-Way-to-Hell Club".

Before its completion in 1937, the bridge was considered "unbuildable" because of foggy weather, high winds and strong ocean currents sweeping through a deep rugged canyon below. Often shrouded in thick fog, the bridge sways 27 feet to withstand winds of up to 100 miles per hour. Weather conditions have closed the bridge on only three occasions.

Paint

The color of the bridge, known as "International Orange", was chosen because it blends well with the bridge's natural surroundings and provides enhanced visibility to passing ships. The PMS code for International Orange is 173, the CMYK colors are Cyan = 0%, Magenta = 96%, Yellow = 100%, Black (K) = 6%

It’s a popular misconception that the bridge is painted “end-to-end” each year. In 1965, due to advancing corrosion, a program to remove the original lead-based paint from the bridge began. The bridge requires routine maintenance on an ongoing basis by a staff of 28 painters and 13 ironworkers.

Materials

US-manufactured steel was used to build the bridge and shipped through the Panama Canal to San Francisco. The two great cables contain enough strands of steel wire (80,000 miles) to encircle the equator three times. The concrete poured into its piers and anchorages would pave a five-foot wide sidewalk from New York to San Francisco.

Toll / Visiting

Pedestrians and bicyclists are allowed across the bridge on pathways with sweeping views of the City, Alcatraz and the Marin Headlands.

The bridge toll for vehicles is $6 collected electronically at the toll plaza when entering San Francisco (no cash payment). Electronic options include FasTrack® and pay-by-plate (toll invoice). A toll invoice is mailed to the registered owner of the vehicle.

Vantage points from the San Francisco side include the Toll Plaza and Visitors Center (before crossing the bridge) and Fort Point (under the bridge). The first exit on the Marin side of the bridge, Vista Point, provides outstanding views of the San Francisco skyline. The best way to see the bridge is to walk across it which takes about an hour round trip. When walking the bridge dress warmly whatever time of year.
