The Golden Gate Bridge requires a lot of paint due to the salt in the air and water, which causes rust and corrosion
The Golden Gate Bridge is one of the most famous and photographed suspension bridges in the world. It was completed in 1937 and was, at the time, the longest suspension bridge in the world. It is renowned for its striking colour, officially known as "International Orange", which was chosen by Irving Morrow, the consulting architect. The reddish-orange primer was originally meant to serve only as a base coat, but Morrow championed the unusual colour, arguing that it was highly visible from the water and through the fog, and blended in with the bridge's natural setting.
Maintenance of the bridge is a continuous task, with a team of inspectors assessing the condition of the bridge and prioritising sections for repainting. The bridge requires so much paint due to the salt content of the air and water in the surrounding area, which causes rust and corrosion. The salt in the air and water comes from the nearby Pacific Ocean, as the bridge is built above the Golden Gate Strait, the entrance to the San Francisco Bay.
The bridge's first coat required approximately 110,000 gallons of paint, and repainting is an ongoing project. In 2021, 2,590 gallons of paint were used, and the annual budget for paint, including sandblasting, is about $300,000. The paint alone adds almost 500,000 pounds to the weight of the bridge.
The Golden Gate Bridge's paint colour has become iconic, and paint supplier Sherwin Williams has even developed a similar colour, Fireweed, for homeowners. The process of painting the bridge is a complex and lengthy task, requiring not only painters but also engineers, ironworkers, electricians, labourers, and carpenters.

The bridge's first coat used approximately 110,000 gallons of paint
The Golden Gate Bridge is one of the most famous and photographed suspension bridges in the world. It was completed in 1937 and was, at the time, the longest suspension bridge in the world. The bridge's first coat used approximately 110,000 gallons of paint, according to a 1938-39 fiscal report. This report also noted that painting was the largest item in the maintenance budget, costing $20,412.
The bridge's paint colour, officially named Golden Gate Bridge International Orange, is a unique feature. It was chosen by Irving Morrow, the consulting architect, who noticed the striking reddish-orange primer painted on some of the steel. Morrow also designed the bridge's lighting and art deco styling. He had to persuade the Department of War, the permitting agency, to allow the unusual colour choice. The U.S. Navy wanted the two giant towers painted with alternating yellow and black stripes, resembling a bumblebee.
The Golden Gate Bridge's paint colour is a significant part of its identity, and it is so well-known that Sherwin Williams, the company that supplies the paint, has developed a similar colour called Fireweed for homeowners. The bridge requires constant repainting due to the salt content of the air and water, which causes rust and steel corrosion. Fred Mixon, the paint superintendent, oversees a team of 28 painters, as well as engineers, ironworkers, electricians, labourers, and carpenters, to maintain the bridge.
The process of painting the bridge is extensive. First, the old paint is removed, and the cables are washed and lightly sanded. Then, two coats of elastic paint are applied, followed by an acrylic coat. This paint job is expected to take four years to complete. The weight of the paint alone adds almost 500,000 pounds to the weight of the bridge.

The bridge is not painted from end to end each year; this is a myth
The Golden Gate Bridge, which spans the Golden Gate Strait, the entrance to the San Francisco Bay from the Pacific Ocean, is one of the most famous and photographed suspension bridges in the world. It was constructed during the worst economic crisis in the nation's history, from 1933 to 1937, with Bay Area residents voting to tax themselves to finance the project. The bridge was the longest suspension bridge in the world at the time of its construction, with painters having to cover more than 10 million square feet of steel.
The bridge's paint colour, officially named Golden Gate Bridge International Orange, is a vivid, unmistakable hue. The consulting architect, Irving Morrow, championed the unusual colour, which was originally meant to serve as a primer. Most bridges were grey, silver, or black, and it was expected that the Golden Gate Bridge would follow this colour scheme. However, Morrow successfully persuaded the bridge builders to keep the bridge the colour of the primer as the final colour. He argued that the colour was highly visible from the water and through the fog and blended in with the bridge's natural setting.
The bridge requires continuous repainting due to the salt content of the air and water, which causes rust and steel corrosion. Fred Mixon, the paint superintendent for the Golden Gate Bridge, Highway, and Transportation District, has stated that the bridge is indeed continuously painted, but it might not go from one end to the other. An inspection team inspects areas on the bridge and then numbers them from high to low priority. If a section is high priority, they address it immediately. For example, Mixon mentioned that they were focused on repainting the south approach section, a project that had been ongoing for three years.
Contrary to the popular myth, the Golden Gate Bridge is not painted from end to end each year. While the bridge does require a significant amount of paint, with estimates ranging from 10,000 to 47,000 gallons, the painting process is not a never-ending chore that starts from the beginning once the end is reached. The painting process is carefully planned and executed by a team of professionals, including painters, engineers, ironworkers, electricians, labourers, and carpenters.

The bridge's paint colour, international orange, was originally meant to be a primer
The Golden Gate Bridge is an iconic structure that has attracted viewpoints from around the world since its completion in 1937. Its distinctive colour, known as "international orange", is a vivid and unmistakable hue that stands out against the foggy San Francisco backdrop.
The bridge's consulting architect, Irving Morrow, first noticed the striking reddish-orange primer painted on some of the steel during construction. Most bridges were painted in more subdued colours like grey, silver, or black, and it was expected that the Golden Gate Bridge would follow this tradition. However, Morrow championed the unusual colour, presenting a 29-page document, "Report on Color and Lighting", to the bridge's board of directors in support of his choice.
The choice of colour was not without its challenges. Morrow had to convince the Department of War, the permitting agency at the time, that the largest suspension span ever built should be painted in this bold shade. The U.S. Navy, for example, preferred a bumblebee-inspired design. Despite these differing opinions, the Golden Gate Bridge's international orange colour has become a trademark, with people requesting paint chips to match their bikes, houses, and fences to the famous bridge.
The Golden Gate Bridge requires constant repainting due to the salt content of the air and water surrounding it, which causes rust and steel corrosion. Fred Mixon, the paint superintendent, oversees a team of 28 painters, engineers, ironworkers, electricians, labourers, and carpenters to maintain the bridge's iconic appearance. In recent years, the annual budget for paint has been about $300,000, with 2,590 gallons of paint used in a single year.

The U.S. Navy wanted the bridge painted like a bumblebee
The Golden Gate Bridge is a 4,200-foot-long iconic structure that has attracted viewers from around the world since the paint first dried in 1937. The bridge was constructed during the nation's worst economic crisis, but Bay Area residents voted to tax themselves to finance the bridge, which connects San Francisco and Marin.
When the time came to choose a colour, a debate began between multiple entities. The U.S. Navy proposed painting the bridge like a bumblebee with black and yellow stripes to maximise visibility for ships and airplanes. This proposal was an attempt to enhance safety by making the bridge stand out against the foggy weather.
However, Joseph Strauss, the project's chief engineer, and his colleagues suggested a carbon black and steel grey scheme, similar to the exterior of other structures in the area. Irving Morrow, a consulting architect on the project, advocated for a warm colour that would complement the surrounding landscape. Morrow's perspective was informed by his daily commute from Oakland to San Francisco, during which he could observe the interplay of light and shadow at the Golden Gate Strait.
Ultimately, Morrow's suggestion of vermilion International Orange was chosen. This colour not only emphasised the structural beauty of the bridge but also provided a warm tone that stood out against the cool grey fog and blue skies of the local atmosphere. The choice of International Orange led to the creation of an iconic landmark that has become synonymous with San Francisco.
Today, the Golden Gate Bridge continues to be a mammoth undertaking in terms of maintenance. The salt content of the air and water surrounding the bridge causes rust and steel corrosion, requiring continuous painting. In recent years, the annual budget for paint has been about $300,000, with 2,590 gallons of paint used in a single year.
