M-231 is the designation of a state trunkline highway in the Lower Peninsula that serves as a partial bypass to US 31 around Grand Haven. This highway was built south of I-96 as an additional crossing over the Grand River. The highway runs from M-45 northward and across the river to a connection with I-96 near the current M-104 interchange. MDOT announced the proposed highway in early November 2006. The new corridor was funded through a Congressional appropriation and a state employment program. The Grand River bridge construction was originally planned for 2010 while the land for the project was being acquired. Other smaller bridges were included in the original plans. Roadway construction was scheduled for 2012. Recent developments in MDOT schedules had construction starting on the Grand River bridge after federal approval was secured with the remainder of the project deferred until additional funding is in place. The road opened on October 30, 2015 as a two lane, limited-access expressway. (more...)
