The Michigan Department of Transportation reports that following the July 4 holiday, the northbound I-75 ramp at Holly Road will close for reconstruction of the northbound I-75 ramps at the Holly Road interchange. Work includes reconstructing the existing ramps and adding a second northbound I-75 entrance ramp. On June 19, one lane on northbound I-75 near Holly Road was closed to begin project staging. During the construction period, traffic will be detoured via Dixie Highway (Saginaw Street, exit 106). Estimated project completion date is October.
