M-71 (Michigan highway)

M-71 is a state trunkline highway in the Lower Peninsula of the US state of Michigan. It serves as a connector between M-21 in Owosso to Interstate 69 (I-69) near Durand. The highway runs along a rail line in a northwest-to-southeast direction in rural Shiawassee County connecting a few small towns along its path.

The highway dates back to the start of the state highway system in 1919. There were some changes made to the routing in the 1930s which increased its length. Two adjacent highways have been rerouted which affected the locations of M-71's termini. The last such change was made in the 1960s when the M-78 freeway (now I-69) was completed near Durand.
