M-20/Isabella Road intersection closed for construction in Mt. Pleasant starting today, Aug. 31

MT. PLEASANT, Mich. - The Michigan Department of Transportation (MDOT) will close and detour the south leg of the M-20/Isabella Road intersection to complete paving operations. This work is part of an overall $19 million investment to rebuild M-20 from Mission Street to US-127. Following the Labor Day holiday weekend, crews plan to shift traffic to the newly built lanes of M-20 and begin rebuilding the north side of the roadway.

M-20 improvements include resurfacing the roadway, signal modernizations, adding a right-turn lane on eastbound M-20 at Isabella Road, replacing the bridge bearings on US-127 over M-20, and pump station improvements. During this work, local municipality contributions will replace sewer and other local utilities.

This year's work is happening from Packard Road to US-127; next year, crews will be working on M-20 from Packard Road to Mission Street.
