Golden Gate Bridge and its International Orange steel towers
Published on 09/24/2026 at 10:47 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Golden Gate Bridge crosses the entrance to San Francisco Bay between San Francisco and Marin County. Its International Orange towers, suspended roadway and sweeping cables form a bridge whose structure remains visible from shore, deck and water.
Golden Gate Bridge across the Golden Gate Strait
The bridge spans the Golden Gate Strait, the narrow waterway connecting San Francisco Bay with the Pacific Ocean. Its main span measures 1,280 metres (4,200 ft) between the towers, while the towers rise 227 metres (746 ft) above the water.
The roadway hangs from two main cables that pass over the tower tops. Vertical suspenders connect the cables to the deck, creating the repeated lines that define the bridge’s profile. The full crossing, including its approaches, extends for about 2.7 kilometres (1.7 miles).
Joseph B. Strauss and the 1937 opening
American engineer Joseph B. Strauss led the bridge project, with Charles Alton Ellis contributing to the engineering and Irving Morrow shaping the architectural treatment. Joseph B. Strauss developed the project during the 1920s.
Construction began on 5 January 1933 and the bridge opened to vehicular traffic on 28 May 1937. Its completion created a permanent road connection between San Francisco and Marin County across the strait. Construction began in 1933.
Steel, cables and International Orange
Galvanised carbon-steel wire forms the main suspension cables. Each cable measures about 36 inches in diameter and stretches roughly 2,332 metres (7,650 ft), while the combined wire length reaches approximately 129,000 kilometres (80,000 miles).
The bridge’s colour is International Orange. Irving Morrow selected the colour for the finished structure, and it remains closely associated with the bridge’s steel towers, stiffening trusses and roadway. International Orange colour appears across the towers, railings and structural members.
Fort Point, a nineteenth-century brick fortification, stands beneath the southern approach. The bridge’s roadway passes above the fort, placing two distinct layers of San Francisco history within the same view. The bridge also moves under changing loads and wind, with its suspension system allowing measured vertical and lateral movement.
Visiting Golden Gate Bridge: what travellers from Western Europe should know
- Golden Gate Bridge links San Francisco with Marin County across the Golden Gate Strait. The southern approach begins near the Presidio, while the northern approach lies beside Fort Baker.
- The bridge carries vehicles, cyclists and pedestrians on separate areas of the deck. The pedestrian route runs along the eastern side of the bridge.
- Golden Gate Bridge is reached from San Francisco by road, bus, bicycle or on foot. The Presidio and Golden Gate National Recreation Area surround the southern approach.
- Fog can cover parts of the towers and cables while the lower roadway remains visible. Wind is a permanent feature of the exposed strait crossing.
