San Francisco’s Golden Gate Bridge weighs approximately 887,000 tons (or 804,670 metric tons), including anchorages and approaches.
In the 1980s, the original concrete road deck was replaced with a lighter, stronger, orthotropic steel deck, reducing the bridge’s total mass by some 12,300 tons (or 11,160 metric tons).
Excluding the anchorages and approaches, the bridge structure weighs approximately 419,800 tons (or 380,800 metric tons).
