How Did the Golden Gate Bridge Flatten?
The Golden Gate Bridge, one of the most iconic bridges in the world, appears to flatten as it stretches across the San Francisco Bay. However, this visual phenomenon is actually an optical illusion caused by the curvature of the Earth. The bridge’s two main towers, which stand at a height of 746 feet above the water, are both perfectly vertical. But as the bridge extends over a distance of 1.7 miles, the Earth’s curvature causes the road deck to gradually appear to flatten out, creating the illusion that the bridge itself is flat.
The Golden Gate Bridge was designed with this optical illusion in mind, and its unique architectural features only enhance the perception of the bridge seemingly flattening out. The Art Deco design of the towers, the modern suspension cables, and the distinct color of International Orange all contribute to the visual impact of this iconic bridge. The Golden Gate Bridge’s design and engineering have made it a beloved symbol not only of San Francisco but of the entire United States.
