Mile Markers in the Florida Keys

Mile Markers (MM) are a relative location of a site in reference to the number

of miles north of Key West. The business center of unincorporated Key Largo is at

about MM 100; therefore, about 100 miles northeast of Key West. The Florida DOT

tries to maintain small rectangular green with white number mile marker signs every

mile on both sides of the highway.

 

Generally except Marathon, addresses along the highway is the MM expressed as

a four, five or six digit number. For example, a business with an address of

100511 Overseas Highway would located at about MM 100.5. If the extreme right

digit (least significant) number is an even number, it is on the west or Bay/Gulf side.

If an odd number it is on the east of ocean side.

 

 

Subtracting two MM's gives the approximate number of miles between two

known locations.

 

If the MM's are getting smaller, one is traveling south or southwest. These are

listed from north to south. Note: the farther south in the Keys one is, the more east and

west the highway runs.

 

Business/commercial location may change or even disappear.

I assume this practice began with Henry Flagler who numbered every mile of

railroad beginning at Jacksonville and ending at Key West. They were white and

black concrete Mile Post signs along therailroad track and on the printed timetables.

This list of MM's are approximate as I have recorded them.

Had a wonderful time at the Lodge. Stayed in the room #7. Saved a LOT of money and kept the driving to a minimum. I really enjoyed our Steak Dinner. Can't wait to get back to the Keys and see my friends at 2287!
