The Michigan Department of Transportation (MDOT) announced today, Mar. 31, the reopening of M-20 (Remus Road) between Sherman Road and Costabella Avenue in Isabella County.

“I would like to thank the contractor and our MDOT staff for their quick response,” said Mt. Pleasant Transportation Service Center (TSC) Manager Jack Hofweber. “Thanks to their hard work and coordination, M-20 was reopened as quickly as possible while ensuring that a quality, temporary fix was in place.”

To repair the failed culvert, sections of concrete pipe were placed to expedite repairs due to delays caused by securing an entire culvert. Crews then began pouring concrete last week to replace the road surface. Once the roadway cured properly to gain the necessary strength, MDOT reopened M-20 to traffic on Tuesday, Mar. 31.

Future work will include building a new, permanent structure, likely in 2027. Shoulder closures will be in place through the end of this week to complete soil borings for the future structure. Work will also be weather dependent.

The original sinkhole formed early Thursday morning, Mar. 12, after a culvert failed on M-20 over Pony Creek prompted MDOT to close the road in both directions.
