Golden Gate Bridge and the span that reshaped San Francisco
Published on 08/30/2026 at 11:14 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Golden Gate Bridge carries road traffic across the Golden Gate Strait between the northern tip of San Francisco and Marin County, its steel deck suspended from two tall towers and sweeping cables. Completed in 1937 as a long-span suspension bridge, it quickly became a defining structure of the San Francisco Bay, known for its orange colour and the way its roadway appears to float high above the water.
An orange suspension span over the Golden Gate Strait
The bridge is a suspension structure with a main span of 4,200 ft (1,280 m) between its two towers, and a total length including approaches of about 8,981 ft (1.7 miles or 2.7 km).The main span figure places it among the important long-span bridges of the twentieth century. Each tower rises about 746 ft (227 m) above the water, giving the bridge a strong vertical presence that can be seen from many points around the bay.The tower height and main span together frame the strait in steel.
The deck carries six lanes of road traffic and two walkways, set within a width of about 90 ft (27 m), with the roadway around 220 ft (67 m) above mean high water at midspan.The main geometric proportions give the bridge a relatively slender profile for its length, accentuated by the parallel lines of the cables and the even rhythm of the suspender rods. End to end, including abutments, it extends for roughly 1.7 miles (2.7 km) from the San Francisco shore towards the hills of Marin County.This overall length makes the crossing feel like a full-scale journey from city streets into open water and back to land again.
Designers, colour and construction era
The bridge belongs to the interwar period of large infrastructure projects in the United States and was completed in 1937 after more than four years of construction that began in early 1933.Construction commenced on 5 January 1933 and the structure opened to public use in late May 1937, when pedestrians and vehicles first crossed the roadway.The May 1937 opening dates mark its arrival as a functioning link across the strait. Chief engineer Joseph Baermann Strauss led the project, with significant engineering contributions from Charles Ellis and Leon Moisseiff and architectural treatment by Irving Morrow.These named figures remain closely associated with the bridge.
Irving Morrow’s role included the choice of the bridge’s distinctive “International Orange” paint, which gives the steel towers and stiffening truss their characteristic appearance against the surrounding landscape.The selection of this colour sets the bridge apart from many grey or silver-coloured steel crossings. The choice sits visually between the blue-green of the Pacific, the pale tones of the city buildings and the browns and greens of the Marin Headlands, making the bridge easy to pick out in photographs and in the varied light that passes through the strait.
Steel, cables and the crossing experience
Golden Gate Bridge is a steel structure, with its main suspension cables formed from galvanised carbon steel wire compacted into large cylindrical bundles about 36 3/8 inches (nearly 92 cm) in diameter.Each cable’s size and composition reflect the engineering demands of a long coastal span. The total wire length in both cables combined has been measured at around 80,000 miles (about 128,700 km), a figure that points to the scale of material required to support the suspended roadway across the channel.The combined wire length is one of the bridge’s more striking statistics.
The structure rests on concrete anchorages and piers, with the towers fixed into the water and the land. Walkways along each side of the deck give views of the bay, the Marin Headlands and the skyline of San Francisco, while the constant movement of vehicles reminds visitors that this is a working transport corridor as much as a viewpoint. The regular spacing of the vertical suspender rods and the lattice of the stiffening truss form patterns that can be traced along the length of the span, and the measured rise of the roadway towards midspan emphasises the height above the strait.
Visiting Golden Gate Bridge: what travellers from Western Europe should know
- Golden Gate Bridge crosses the Golden Gate Strait between the northern tip of San Francisco and Marin County in California, and it is reached by road from both sides of the bay.
- The deck includes pavements on both sides, and approaching the bridge on foot involves roadside paths and walkways exposed to coastal wind and weather.
- On the San Francisco side, the bridge lies near the Presidio and Crissy Field, while on the Marin side it rises close to the Marin Headlands and the entrance to the coastal hills.
- The official language is English and the currency is the United States dollar.

Frequently asked questions about Golden Gate Bridge
Where is Golden Gate Bridge located?
Golden Gate Bridge spans the Golden Gate Strait between San Francisco and Marin County in California, forming part of the regional road network across the bay entrance.
What should visitors expect when crossing?
The bridge carries road traffic on six lanes with pavements on both sides, offering views of the bay and the Pacific while remaining exposed to wind and coastal weather.
What makes Golden Gate Bridge distinctive among bridges?
Its combination of a 4,200 ft (1,280 m) main span, tall steel towers and International Orange colour over a Pacific strait gives Golden Gate Bridge a recognisable profile and strong visual impact.
