US-31/M-231 near Nunica, Ottawa County

Construction of the new M-231 Grand River Bridge is expected to begin in 2011MDOT will construct a new two-lane, limited access roadway (M-231) from M-45 (Lake Michigan Drive) north to the I-96/M-104/112th Avenue interchange area near Nunica, Ottawa County. It will be located west of the existing 120th Avenue roadway. A new bridge over the Grand River along this new route will be constructed making it only the 4th river crossing in Ottawa County. M-104 improvements near the M-231 intersection, a new I-96 interchange at M-231, and adding ramps to the I-96/112th Avenue interchange (westbound on and eastbound off ramps) are included with the M-231 project.

Improvements to existing US-31 are also planned for a short segment in Grand Haven ( Franklin Street to Jackson Street), and in Holland Township (Lakewood Boulevard to Quincy Street).

Design and Right of way acquisition began in 2010. Construction of the new M-231 Grand River Bridge is expected to begin in 2011. Additional segments will be constructed as indicated on the following proposed schedule. The timing for completion of all phases of the project will depend on statewide funding availability.
