Traffic crossing the Blue Water Bridge into Michigan will be detoured through Port Huron this weekend.
The Michigan Department of Transportation said a portion of westbound I-94 will be closed for maintenance.
The interstate will be closed just west of the Blue Water Bridge customs plaza for construction starting at 6 a.m. Saturday.
Traffic on westbound I-94 will be rerouted through the eastbound I-94 business loop to Hancock Street, Pine Grove Avenue, Huron Avenue, Military Street and westbound I-94 business loop.
The construction, which includes paving and bridge repairs, is expected to be completed by 7 a.m. Monday.
