Sugarloaf Key - Learn More

Sugarloaf Key in the Lower Keys is located on US Hwy. 1 at mile marker 20.5. It is a single island in the lower Florida Keys that forms a loop on the Atlantic Ocean side giving the illusion of separate islands. Although frequently referred to simply and with technical accuracy as "Sugarloaf Key", this island contains two distinct island communities, known as Lower Sugarloaf Key and Upper Sugarloaf Key. The island is somewhat "U"-shaped, with Upper Sugarloaf Sound and Park Key separating the island into Upper Sugarloaf Key and Lower Sugarloaf Key. So called, upper and lower, simply referencing the relative nature of their geographic positions, not as distinct islands.

Key West - Learn More

Key West in the Lower Keys is located at the end of US Hwy. 1 and represents the southernmost portion of the United States.

Key West was relatively isolated until 1912, when it was connected to the Florida mainland via the Overseas Railway extension of Henry M. Flagler's Florida East Coast Railway (FEC). Flagler created a landfill at Trumbo Point for his railyards. The Labor Day Hurricane of 1935 destroyed much of the railroad and killed hundreds of residents, including around 400 World War I veterans who were living in camps and working on federal road and mosquito control projects.

The U.S. government then rebuilt the rail route as a highway, completed in 1938, which became an extension of United States Highway 1. The portion of U.S. 1 through the Keys is called the Overseas Highway. Franklin Roosevelt toured the road in 1939.

Numerous artists and writers have passed through Key West, but the two most associated with the island are Ernest Hemingway and Tennessee Williams.
