Which U.S. Route crosses San Francisco's Golden Gate Bridge?

U.S. Route 101 crosses San Francisco’s Golden Gate Bridge.

The highway approaches the bridge through San Francisco’s Presidio, crosses the Golden Gate strait, and continues north through Marin County as the Redwood Highway. The bridge therefore forms a crucial link between San Francisco and the North Bay, connecting the city with communities and roads farther north.

California State Route 1 also crosses the Golden Gate Bridge, running concurrently with U.S. Route 101 on this section. That creates a common quiz mix-up: California Route 1 is a state highway, while the question asks specifically for a U.S. Route. U.S. Route 1 does not cross the bridge.

The Golden Gate Bridge opened to traffic on May 27, 1937. Its main span measures 4,200 feet, and at opening it was both the world’s longest and tallest suspension bridge. The bridge is operated by the Golden Gate Bridge, Highway and Transportation District.
