The construction of the Golden Gate Bridge, which took place between 1933 and 1937, was considered one of the greatest engineering feats of its time due to the treacherous conditions of the Golden Gate Strait, including deep waters, strong tides, fog, and high winds.
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.
