History of the Key West drive

The road to Key West was built on the trail of a railroad originally built from 1905 to 1912. Some parts of the railroad are still up to this day but some parts of the tracks were destroyed by a hurricane just a few years after its completion. The pharaonic project that cost more than 50 million dollars and was considered an engineering masterpiece was destroyed in 1935.

The state of Florida bought the remaining of the tracks and started building the Overseas Highway on what was left after the hurricane in the 1930s. By 1987, 37 bridges were replaced to make the road wider and easier to drive. The Seven Mile Bridge was built from 1978 to 1982.

Works to restore the original bridges for pedestrian use are still going on. The old bridge going along the Seven Mile Bridge is due to be restored in 2021.
