Introduction
The Overseas Highway is more than just a road—it's a journey through paradise. Stretching 113 miles from mainland Florida to Key West, its most unique feature is the mile marker system, a series of small green signs that line the highway, that count down to 0.
These markers are the ultimate travel guide for exploring the Florida Keys—they help visitors locate attractions, restaurants, beaches, and iconic stops.
So, here’s a handy guide to navigating the Overseas Highway with Shaka Guide, using mile markers to ensure you don’t miss a thing!
How do you use mile markers?
The mile marker system on the Overseas Highway in the Florida Keys is an easy way to find your way around the islands.
Each island, or key, has mile marker signs, making it easy to find famous spots. Locals and businesses often use these markers for directions.
The system also divides the highway into bayside (west) and oceanside (east), depending on the location relative to the water.
Rather than an address, you'll often hear instructions like, "We're at Mile Marker 81 on the bayside."
