The Overseas Railroad (also known as Florida Overseas Railroad, the Overseas Extension, and Flagler's Folly) was an extension of the Florida East Coast Railway to Key West, a city located 128 miles (206 km) beyond the end of the Florida peninsula. Work on the line started in 1905^[2] and it operated from 1912 to 1935, when it was partially destroyed by the Labor Day Hurricane. Some of the remaining infrastructure was used for the Overseas Highway.
