ISHPEMING, Mich. ­- The Michigan Department of Transportation (MDOT) is investing about $3.6 million to replace a culvert on M-35 over Warner Creek north of Palmer in Marquette County. Work includes replacing the existing structure with a concrete box culvert, asphalt rebuilding and pavement markings.

Northbound and southbound M-35 will be closed at Warner Creek beginning July 27 with a posted detour on US-41 and M-553. The detour is expected to last two weeks.
