The Overseas Highway, the southernmost leg of U.S. Highway 1 and sometimes called the Highway That Goes to Sea is a modern wonder. The road, that follows a trail originally blazed in 1912 by Henry Flagler's Florida East Coast Railroad, stretches from Miami to Key West.
The Overseas Highway is a 127.5-mile (205.2 km) highway carrying U.S. Route 1 (US 1) through the Florida Keys. Large parts of it were built on the former right-of-way of the Overseas Railroad, the Key West Extension of the Florida East Coast Railway. Completed in 1912, the Overseas Railroad was heavily damaged and partially destroyed in the Labor Day Hurricane of 1935
