Golden Gate Bridge: The Icon of San Francisco
Location: The Golden Gate Bridge spans the Golden Gate Strait, the narrow channel connecting San Francisco Bay with the Pacific Ocean. It links San Francisco with Marin County and is one of the most distinctive landmarks along the California coast. From the bridge and nearby viewpoints, sweeping views stretch across the bay, the coastline and the Pacific.
Significance: Few structures are as closely associated with San Francisco as this world-famous suspension bridge. When it opened in 1937, its 1,280-metre main span set a new world record that remained unbroken for more than 27 years. It was finally surpassed in 1964 by the Verrazzano-Narrows Bridge in New York. Today, the Golden Gate Bridge remains one of San Francisco’s most famous landmarks and an important transport link to Marin County.
Previous Connection: Before the bridge was built, ferries provided the main direct connection between San Francisco and Marin County. Ships had been operating between San Francisco and Sausalito since 1868, with car ferries introduced later. As the population grew and road traffic increased, demand for a permanent crossing over the strait became increasingly strong.
Construction History: Construction began on January 5, 1933, in the middle of the Great Depression. The project was financed through bonds worth $35 million, although sales were initially slow. The decisive breakthrough came with the support of banker Amadeo Giannini, founder of Bank of America. After just over four years of construction, the bridge opened in May 1937, ahead of schedule and below its original budget. A toll has been charged for crossing the bridge ever since it opened in 1937. Since 1968, the toll has only been collected in the direction of San Francisco. Today, the fee is collected entirely electronically and helps fund the operation and maintenance of the Golden Gate Bridge.
Foundation Work: Building the foundation for the southern tower was particularly demanding because it stands around 335 metres offshore. Divers worked at depths of up to 33 metres in cold water, powerful currents and extremely poor visibility. Beneath the surface, they blasted and removed rock and debris until they reached stable ground. The massive foundation could then be safely built on this solid base.
Innovative Safety Measures: Safety standards during construction were unusually advanced for the time. In addition to hard hats and other protective equipment, a large safety net was installed beneath the roadway. It saved the lives of 19 workers who fell during construction. They later became known as the “Halfway-to-Hell Club”. Even so, 11 people lost their lives during the building work. Ten of them died on February 17, 1937, when a scaffold collapsed and the safety net gave way under the impact.
Earthquake During Construction: In June 1935, an earthquake struck the region while the southern tower was still under construction. One worker later reported that the top of the tower swayed back and forth by around five metres. Despite the dramatic movement, the structure remained stable, and the workers on the tower came through the event without injury.
Protection Against Natural Disasters: The Golden Gate Bridge is designed to move in a controlled way during strong winds. Its roadway can sway sideways by several metres without putting the structure at risk. Since the 1990s, the bridge has also been reinforced in stages to improve its resistance to major earthquakes. In extreme wind conditions, it can be temporarily closed to traffic as a precaution.
Architecture: The Golden Gate Bridge is a classic suspension bridge with a total length of 2,737 metres and a width of 27 metres. The suspension section itself is 1,966 metres long. Its 1,280-metre main span stretches between two steel towers rising 227 metres above the structure. At the centre, the roadway runs around 67 metres above the water and is supported by two massive main cables. Each cable contains 27,572 individual steel wires. Laid end to end, the wires from both cables would stretch for around 129,000 kilometres, enough to circle the Earth more than three times. Around 75,300 tonnes of steel were used in the original structure. Clean lines, geometric shapes and carefully designed details define the Golden Gate Bridge’s distinctive Art Deco style.
Iconic Colour: The Golden Gate Bridge owes its distinctive colour to architect Irving Morrow. He chose the shade to complement the surrounding landscape while creating a strong contrast with the sea, sky and frequent fog. Grey and black were among the colours considered beforehand. For visibility reasons, the US Navy even preferred a black-and-yellow striped paint scheme. The salty, humid air continues to corrode the steel to this day. Damaged areas are therefore regularly cleared of rust before receiving a new protective coating and the bridge’s characteristic orange topcoat.
Opening: On May 27, 1937, the Golden Gate Bridge was reserved entirely for pedestrians. Around 200,000 people took part in the so-called “Pedestrian Day”, crossing the new bridge on foot and experiencing it up close. One day later, it opened to motor traffic and began regular operation.
Anniversary: To mark the 50th anniversary of the Golden Gate Bridge in 1987, around 300,000 people crowded onto the roadway during the four-hour Bridgewalk. Under the enormous weight, the shape of the bridge changed so dramatically that its normally upward-curving roadway appeared almost flat. Despite this exceptional load, the structure remained within its designed safety limits and suffered no damage.
Heavy Traffic: On average, more than 100,000 vehicles cross the Golden Gate Bridge every day. Its six traffic lanes can be flexibly divided between the two directions depending on traffic conditions. Since opening in 1937, more than two billion vehicles have crossed the Golden Gate Bridge. The one-billionth vehicle was recorded on February 22, 1985.
Suicide Prevention: The Golden Gate Bridge also has a tragic history, with numerous suicides occurring there over many decades. To prevent further deaths, a safety net was installed along the entire bridge, forming a continuous protective barrier since the beginning of 2024. The measure is already showing an effect: in 2024, the number of suicides was 73 percent below the long-term average of the previous 20 years.
Origin of the Name: The Golden Gate Bridge takes its name from the strait it spans. As early as 1846, American explorer John C. Frémont referred to this entrance to San Francisco Bay as the “Golden Gate”. He was inspired by the Golden Horn in Istanbul, which reminded him of the location and shape of the strait.
