(TUSCOLA COUNTY) -- MDOT crews will begin work on a $9.5 million construction project to resurface and make road improvements on M-25 from west of the Bay/Tuscola County line, and then east to the Bay Park Road intersection. Construction is slated to start Monday, April 15 and will include milling, resurfacing, shoulder widening, drainage improvements, and safety upgrades. Alternating single-lane closures will be in effect under flag control. Work on a separate project, M-25 over the Quanicassee River in Tuscola County, will continue with traffic detoured through mid-June. The entire project is expected to be complete by late August 2013.
