Minute Order 115878, dated 10/29/2020

In the City of McKinney, a segment of FM 546 was removed from the state highway system from SH 5 eastward along Industrial Boulevard, then southward and eastward along Wattley Way to the intersection of new FM 546, a distance of approximately 2.2 miles. Control, jurisdiction, and maintenance were transferred to the city of McKinneya. Minute Order 115878 does not address the designation of FM 546 along a new location on the state highway system from another point on SH 5, approximately 0.3 mile south of the intersection of former FM 546, southeastward to the intersection of Wattley Way (former FM 546), a total distance of approximately 1.6 miles. This relocation of FM 546 was constructed and is therefore noted here despite its omission from any Minute Orderb. (Collin County)
