Modern Marvels - Season 10 - Eps 53: Overseas Highway
A spectacular roadway nearly 120 miles long, the Overseas Highway links mainland Florida with the Florida Keys, and contains 51 bridges, including the Seven-Mile Bridge. A boat was the only mode of travel from Miami to Key West until oil tycoon Henry Flagler completed his railroad line in 1912. After a 1935 hurricane destroyed 40 miles of track, the scenic highway was built using Flagler’s bridges. A $175-million refurbishment that ended in 1982 resulted in today’s remarkable Overseas Highway.
