Overseas Highway, Highway in Key Largo, United States
The Overseas Highway is a road route in Key Largo, Florida, that runs through the Florida Keys and links several islands together. The route crosses many bridges that span the open waters of the Atlantic and the Gulf of Mexico, covering a distance of roughly 113 miles (182 km).
The road was built after a major hurricane in 1935 on the old railway bed of the Florida East Coast Railway. The storm had destroyed large sections of the railroad infrastructure and made the construction of a new connection necessary.
The route received designation as an All-American Road in 2009, joining a select group of 30 highways recognized by the Federal Highway Administration.
Travelers can find their way along the route using mile markers, with the Key Largo section running from marker 107 to marker 91. The drive offers open views of the water in many places and is suitable for stops at parking areas along the route.
The Seven Mile Bridge section stands as one of the longest bridges globally, offering views of three bodies of water: the Atlantic Ocean, Florida Bay, and Gulf of Mexico.
