M-50 begins the final leg of its journey, as it crosses into Monroe county, passing through land that is mostly fields. Prior to reaching its interchange with US 23, the highway passes to the south of Cabela's, a outdoor sports retailer in Dundee. After leaving town, the trunkline continues to the southeast, running to the south of the River Raisin, through rural areas as South Custer Road before entering the outskirts of Monroe where it finally ends its journey at a junction with US 24 (Telegraph Road) a few miles inland from Lake Erie.
