Stretching 1.7 miles across the Golden Gate Strait, connecting the San Francisco Bay to the Pacific Ocean, the Golden Gate Bridge is an instantly recognizable icon that dominates the San Francisco skyline. One of the city’s top attractions, this engineering marvel is a wonder to behold, with tons of interesting details hidden beneath its 20th-century facade.

Before the bridge was built, a ferry service operated between Marin County and the San Francisco Peninsula.

In the early 1900s, plans to link the two were first developed, and decades later, on January 5, 1933, work on the bridge project began. During the bridge’s construction, a safety net was strung beneath to help prevent laborer deaths—and it saved 19 lives.

On May 27, 1937, the Golden Gate Bridge opened to the world, and today it’s one of the most famous spans in the world. Here are five little-known facts about City by the Bay’s best-known symbol.


1. Its signature color was created specifically for the Golden Gate Bridge

The Golden Gate Bridge has architect Irving Morrow to thank for its vibrant orange-red hue. Though the striking color—called International Orange—is widely used in the aerospace industry, this version is unique to the suspension bridge itself.

The shade is slightly lighter than you might see on an astronaut’s spacesuit, and the paint itself was formulated to be rust-resistant against the salty spray of the water. Safety concerns were also taken into account: The bright orange color makes the bridge more visible in the thick fog often engulfing the San Francisco Bay.


2. More than 2 billion cars have crossed the Golden Gate Bridge

On February 22, 1985, the one billionth driver, Dr. Arthur Molinari, crossed the Golden Gate Bridge. (He was gifted a case of champagne and a hardhat in celebration.) As of 2019, those numbers had more than doubled, and two billion–plus cars have driven over it to date, according to the latest tallies.


3. So many people attended its 50th anniversary, the Golden Gate Bridge flattened

On May 24, 1987, the City of San Francisco held a celebration to mark the Golden Gate Bridge’s 50th anniversary, closing it to traffic to allow people to walk across. Officials only expected 50,000 people to show up; instead, between 750,000 to 1,000,000 arrived.

Roughly 300,000 people crowded onto the suspension bridge, weighing it down so much that the curved arch completely flattened and lowered the bridge by 7 feet.


4. The Golden Gate Bridge was hit by an earthquake before it was even finished

In June 1935, a strong earthquake hit the Golden Gate Bridge while it was still being built. Construction workers on top of the South Tower reported that the pillar swayed 16 feet from side to side.


5. The Golden Gate Bridge is a Hollywood star

This famous bridge is also a silver-screen star. It’s been featured in dozens of films, including the 1985 James Bond flick, A View To A Kill, and 2011’s Rise of the Planet of the Apes. Perhaps because of its real-life strength and indestructibility, directors seem to love to reduce it to rubble, as evidenced in films like 1955’s It Came from Beneath the Sea.



More interesting facts about the Golden Gate Bridge:


  • It’s the most photographed bridge in the world.
  • The bridge is constantly being painted to maintain its vibrancy. Its International Orange color is made by Sherwin Williams.
  • Portugal’s 25 de Abril Bridge is the only other bridge in the world featuring this exact shade of International Orange.
  • When the Golden Gate Bridge opened in 1937, it was both the longest suspension bridge and the tallest suspension bridge in the world.
  • Thanks in part to its parallel wire construction, the Golden Gate Bridge is strong enough to withstand magnitude 8 earthquakes.
  • The bridge takes its name from the Golden Gate Strait it crosses, connecting the San Francisco Peninsula to Marin County.
  • The Golden Gate Bridge’s cables were made by the same company that supplied them for the Brooklyn Bridge.


The Golden Gate Bridge is a marvel of the modern world, with a history just as fascinating as the bridge itself
