Did the Golden Gate Bridge flatten?
San Francisco celebrated the 50th anniversary of the Golden Gate Bridge on May 24, 1987 with a bridge walk. The bridge began to groan and sway with an estimated 300,000 people packed like sardines onto it. The middle of the bridge sagged seven feet under the unprecedented weight, causing the iconic arch to flatten.
Does the Golden Gate Bridge move?
The Golden Gate is designed to move up and down (10 feet, or 3 meters), and side-to-side (21 feet, or 6.4 meters, each way). What makes it move? Traffic weight and wind. When the winds are blowing hard, you can feel some movement if you’re walking across.
What is on the north side of the Golden Gate Bridge?
The north side of the bridge is in Marin County, where you’ll see the city as a backdrop for the bridge. You can drive up into the Marin Headlands, where you’ll find several stops. Or you can go down to the water’s edge for a scenic and less-seen view, too.

What type of plate boundary is Golden Gate Park?
Located where the North American and Pacific tectonic plates meet, Golden Gate National Recreation Area is truly a park on the edge. The park is situated along the San Andreas fault, where the two tectonic plates slide past each other to produce earthquakes and actively moving landforms.
