A mile marker along M-14 in 1922. From that year's biennial state highway commissioner's report:

The diamond mile post markers are numbered consecutively from the point of origin of the trunk line to its end. The numbers are placed on the metal post directly under the diamond. The origin of the trunk line is considered to be at the east or south end of the route and is at the State line or at the intersection of two trunk lines
