In late 2019, high water levels and winter storms damaged sections of the highway, and MDOT initiated emergency repairs including some erosion mitigation measures at a projected cost of $350,000. Further reconstruction work was started in 2020 to repair about half of the highway at a cost of about $1.4 million. M-185 was closed at the state park boundary north of the Mission Point Resort to British Landing, a distance of about in mid-June. This project includes the installation of rip-rap to help protect the roadway from rising water levels in the Great Lakes. MDOT plans to have the project completed by mid-September and to open sections of the highway to tourist traffic in stages as work is completed, starting with the stretch north to Arch Rock. Additionally to accommodate tourists, the roadway will be initially rebuilt with a gravel surface to be paved later in the year as work progresses.
