MILE MARKERS

Down here in the Keys, the Overseas Highway is like our Main Street. And the best way to get around is to know the mile marker of your destination. These little green signs that dot our highway every mile begin just south of Florida City with number 127 and run all the way down to zero in Key West. They’re like our addresses. If you know the mile marker of where you’re going, getting there is easy.

As you travel the Florida Keys you will come to appreciate the green and white mile markers (MM) on US 1. These roadside markers tell you how far you are from Key West from anywhere in the Keys. The mile marker numbers begin with 127 (south of Florida City) and end with 0 in Key West - the Southernmost city in the United States. Addresses and maps often include mile markers for easier location.
