M-18 detour lifted in Roscommon County
November 18, 2019 -- M-18 between Roscommon and Prudenville, closed since Sept. 3 to replace the Backus Creek culvert, has been reopened as of Friday afternoon.
Crews working on the $1.2 million Michigan Department of Transportation (MDOT) project were able to complete the project to a point that allowed lifting the detour, which originally was expected to occur by mid-October. Lane closures with flag control are likely over the next week for completion of slope restoration work.
"Unfortunately, this project took longer to complete than expected for several reasons, including weather and some unexpected underground conditions," said MDOT Gaylord Transportation Service Center (TSC) Construction Engineer Brad Swanson. "We appreciate residents' and drivers' patience through this extended closure and detour."
The project included removal of an existing bridge and replacement of the large culvert that carries Backus Creek beneath M-18, as well as reconstructing the roadway approaches, new guardrail, curb and gutter, and other drainage and safety improvements. During construction, M-18 traffic was detoured on I-75 and M-55.
