"M" . "19006.4"^^ . "North" . . . . "South" . "1919-07-01Z"^^ . . . "93" . . "M-93 is the designation of a state trunkline highway in the Lower Peninsula of the US state of Michigan. It links both Camp Grayling and Hartwick Pines State Park with Interstate 75 (I-75). Both termini of M-93 end at locations, rather than junctions with another road. The western end of M-93 ends in a traffic circle before it turns into Howe Road as it travels through Camp Grayling. The highway dates back to 1919 as a connection with the predecessor to Camp Grayling."@en .
