 M @-@ 114 was the designation of a former state trunkline highway and planned <unk> in the US state of Michigan around the city of Grand Rapids . It was designated by the end of 1929 on various streets in adjoining cities and townships . By the 1940s , sections of it on the west and south sides of Grand Rapids were given new designations and the segment along the east side of town was finished . By late 1945 the highway designation was completely decommissioned in favor of other numbers . M @-@ 114 split into two branches , one running east – west and the other running north – south . The east – west spur routing is now local streets while the rest is part of state highways .
