Mileposts (or mile markers) along highways and their locations collection during GPS mapping efforts in the early 2000s from the Colorado Department of Transportation (CDOT).

Colorado Highway and Frontage road milepost locations. Mileposts are locations of milepost (mile marker) locations alongside CDOT highways, collected during GPS mapping efforts in the early 2000s. MIleposts differ from milepoints in that milepoints represent the location along CDOT highways where that highway's linear reference system indicates a whole number reference point (such as 57.000). Therefore, mileposts are not necessarily found at exactly at milepoints. Also includes collection date of point, route ID and some GPS locations.

Local Roads are functionally identified as local and excludes major roads or highways. Each road is segmented with a to and from description. The direction, length, type (paved/dirt), width (in feet), local route name and id, number of lanes, one/two-way bridges, average daily traffic counts, locations of count stations, if it is congested, if maintenance is under shared jurisdiction and the year it was built or last updated from the Colorado Department of Transportation (CDOT).
