Construction of the Golden Gate Bridge began on January 5, 1933, and it was completed in just over four years, opening to traffic on May 28, 1937. The iconic structure cost roughly $35 million to build, linking San Francisco to Marin County. If the bridge were to be built from scratch today, the cost would skyrocket far beyond simple inflation due to modern labor laws, environmental regulations, and advanced seismic engineering requirements.
Experts estimate the true replacement cost would be: $10 billion to $35 billion.
