The FEC is possibly best known for building the railroad to Key West, completed in 1912. When the FEC's line from the mainland to Key West was heavily damaged by the Labor Day Hurricane of 1935, the State of Florida purchased the remaining right-of-way and bridges south of Dade County, and they were rebuilt into road bridges for vehicle traffic and became known as the Overseas Highway. However, a greater and lasting Flagler legacy was the developments along Florida's eastern coast.
