Minute Order 115371, dated 11/15/2018 (Rescinds Minute Order 105686)

Minute Order 105686: From US 80 in Baird, westward to UR 18 [FM 18] in Elmdale Community, a distance of approx. 16.387 miles. (Taylor and Callahan Counties)  Mileage from Elmdale westward to SH 36 transferred to UR 18.

Minute Order 115371 general description: Minute Order 115371 rescinds Minute Order 105686. The result of this rescission is the elimination of the Urban Road (UR) system. The Farm to Market (FM) and Ranch to Market (RM) roadways which were intended to be redesignated as Urban Roads under the provisions of Minute Order 105686 revert back to their FM/RM designations. Minute Order 115371 declares that the provisions of Minute Order 105686 were never implemented, and although the UR designations were in effect during the interim between these two Minute Orders, the affected roadways continued to be referred to by their FM or RM designations. Only the Highway Designation Files made reference to the UR designations during this interim period. Upon the passing of Minute Order 115371, the affected Highway Designation Files have been updated retroactively to reflect the FM/RM designations.

Minute Order 115371 as it affects FM 18: Any mileage that was previously described as "transferred to UR 18" reverts back to FM 18. This is retroactive to the date of passage of Minute Order 105686. The Highway Designation File page for UR 18 has been removed.
