133 Fun Florida Keys Mile Markers and Map of Florida Keys

Getting to Mile Marker 0 Key West

Mile markers in the Florida Keys are critical to finding locations in the forty-plus islands. Addresses do exist, but many are hard to see or have been destroyed by storms.

We update Florida Keys mile markers on each of our trips. Our last update was on August 2, 2023.

Florida Keys mile markers in the Florida keys map - mile marker 0 Key West
Your destination is mile marker 0 in Key West Florida.

The Florida Department of Transportation maintains green and white mile marker signs along both sides of the road. The signs start at MM 0 Key West and increase every mile as US 1 winds its way east.

Where do the mile markers in the Florida Keys start? 

For our purposes, we start at MM126.5. This is the junction of US 1 and Card Sound Road as you head into the Keys. Card Sound Road also ends up in Key Largo but takes a circuitous route.

It should be noted that Alabama Jacks, a rustic Florida restaurant, is located along Card Sound Road. There is also a turn-off to an exclusive country club called Ocean Reef Club before getting into the Keys.

Note that different points between locations are noted in tenths of a mile. Therefore, as noted above, our beginning point is .5 of a mile from MM126. These are our calculations – you won’t find signs in tenths of a mile.

Where are the Florida Keys? As you can see from the Map of Florida Keys, they are the southern protrusion of some 800 islands from the southeast corner of Florida.

Key Largo, the largest of the Keys, is 66 miles south of Miami.

Understanding the  Florida Keys Mile Markers

If we say there is a location at 66.2, that means it is .2 of a mile from the 66 MM sign. Since we start with the higher numbers, it would also mean the location is .8 of a mile from MM67.

If you do see an address, the odd numbers are located on the ocean side. Even numbers are on the Florida Bay side (aka, gulfside).

You can determine mileage by simply adding or subtracting numbers. For instance, the 7-mile bridge begins at MM40. That is 40 miles from MM0 at Key West. The other end of the bridge is MM47 – strangely, the 7-mile bridge is 7 miles long!

Note that things occasionally change. Fixed bridges may be replaced with draw bridges.

Businesses may go out of business or change their name. We are publishing this for May 1, 2023. Updates will be made to the mile markers in the Florida Keys as we return.

How to Use the Mile Markers of the Florida Keys

You can’t possibly keep track of all the locations noted here. The Florida Keys Mile Markers guide will keep you from getting lost. We also highlight in orange those places the Florida Travel Blog recommends as you travel the Keys.

What are the names of the Florida Keys? There are over 100 names in the link above, but there are many islands that have local names that are not on many maps.

Many names are on the mile markers of the Florida Keys below, but not all.
