The Missouri Department of Transportation is urging motorists to use extreme caution as they begin working on two roadways in Miller County. Contractors will overlay Route 17 to Route 52 to Route 42 and Route 52 from Route 54 to Route 17. Both roadways will get widened shoulders and rumble strips. There is a possibility of lane closures and minor delays through the duration of the work. MODOT plans to complete these improvements in the fall.
