 As it crosses the river, M-231 angles northeasterly before intersecting M-104 the latter's eastern terminus at I-96, and M-231 continues north to its own northern terminus at a new partial interchange with I-96.Even though it does not physically connect to that highway, M-231 is a scaled-down bypass of US 31 through Grand Haven.The highway is expected to reduce response times for emergency services in the area by shortening the driving distance across the Grand River.
