What is the name of the suspension bridge that connects San Francisco to Marin County?

The suspension bridge that connects San Francisco to Marin County is the Golden Gate Bridge.

The bridge spans the Golden Gate, the roughly one-mile-wide strait between San Francisco Bay and the Pacific Ocean. It links San Francisco at the northern end of the San Francisco Peninsula with Marin County, carrying U.S. Route 101, California State Route 1, bicycles, and pedestrians. Its main span stretches about 4,200 feet, and the bridge opened to traffic on May 27, 1937.

Before its construction, ferries provided the principal connection between San Francisco and Marin County. Many engineers considered a bridge impractical because of deep water, powerful currents, heavy fog, strong winds, and the strait’s exposed location. Chief engineer Joseph Strauss led the project, while Leon Moisseiff, Charles Ellis, and architect Irving Morrow made important engineering and design contributions.

The Golden Gate Bridge is often confused with the nearby San Francisco–Oakland Bay Bridge, which crosses the eastern part of San Francisco Bay. Despite its name, the bridge is not painted gold; its distinctive color is officially called International Orange.
