Construction got underway Monday on Highway 109 from Wells to Alden and motorists will be detoured around the project.
Highway 109 will be closed during construction and motorists traveling from Wells will be detoured south on Highway 22 and east on Interstate 90 to Alden.
The 10 miles of construction will include resurfacing the existing pavement and replacing more than 20 culverts.
A construction company from Wisconsin was awarded the bid for the project at $5.8 million.
MnDOT urges motorists to drive with caution in and around the construction and detour area.
