Mile Markers

- Mile Markers in the Florida
Keys
| Mile Markers (MM) is 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. This was compiled early 2003. |
| 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 the railroad track and on the printed
timetables. This list of MM's are approximate as I
have recorded them. Items listed in italics are
historical locations and may not still physically
exist. |
