Isabella County, MI — Emergency road repairs forced the closure of M-20 between Sherman Road and Costabella Avenue, disrupting traffic in both directions.
According to the Michigan Department of Transportation (MDOT), the shutdown was issued as crews respond to urgent roadway repair needs along the M-20 corridor in Isabella County. Officials said the highway is closed in both directions while crews work in the affected area.
MDOT posted the alert on social media shortly before the closure, warning drivers that the roadway would be inaccessible between the two rural intersections until repairs are completed. A state traffic map showed the closure centered near W. Remus Road (M-20) where maintenance crews were dispatched.
Authorities have not yet released an estimated reopening time.
Drivers traveling through the area are advised to seek alternate routes and expect delays, particularly for those traveling between western Isabella County and neighboring communities.
The affected segment of M-20 serves as a key east-west route connecting rural areas with nearby population centers, including Mount Pleasant and surrounding townships. Closures on this corridor can quickly affect local commuters and delivery traffic.
Students and young workers who rely on the route to travel between small communities and nearby schools or jobs may also encounter longer travel times while repairs continue.
MDOT has not reported injuries or additional incidents related to the closure. Updates about reopening or detours are expected to appear on the state’s official traffic information system as crews assess the roadway and complete repairs.
Motorists are encouraged to monitor MDOT alerts and drive cautiously near work zones.
