In general, the mile markers are measured from west to east and south to north. Such as I-10 starting in Escambia County, bordering Alabama, with mile marker 1 then increases eastward. And for I-95 from Miami-Dade County starting with mile marker 1 then increases northward. The data is refreshed weekly and changes are made by the District Offices who are responsible to collect and upkeep the data. This data may also be collected for call boxes that are located at integral milepoints instead of the usual mile marker signs. This data is required for all interstate, tolled or non-tolled expressway facilities, and US routes. This dataset is maintained by the Transportation Data & Analytics office (TDA).

This label service is generated from a subset of the Common Places layer maintained by the Tallahassee - Leon County Consolidated Dispatch Agency. This label service displays mile markers on Interstate 10 and Orchard Pond Parkway. Because Interstates are limited access roadways, they do not include address ranges, which makes mile markers a critical location reference for first responders. While the Common Places layer is actively edited by staff at the Consolidated Dispatch Agency and Emergency Management, the Mile Marker subset is considered static.

A point feature class of the Florida Turnpike mile marker signs posted on the roadway (may also be referred to as mile points) within Miami-Dade County. This layer contains the Turnpike milemarker signs in Miami-Dade County. A stone marker set up on a roadside to indicate the distance in miles from a given point. On most interstates, mile marker numbers begin at the south state line on north-south routes and increase as you travel north. On east-west routes, the numbers begin on the western state border and increase as you travel east.Updated: Not Planned The data was created using: Projected Coordinate System: WGS_1984_Web_Mercator_Auxiliary_SphereProjection: Mercator_Auxiliary_Sphere
