The Michigan Department of Transportation (MDOT) is investing approximately $90 million in St. Clair County to widen and reconstruct 2 miles of eastbound and westbound I-94/I-69 between Lapeer Road and the Blue Water Bridge in Port Huron. Work includes replacing the I-94/I-69 bridge over the Black River; new interchanges and replacing the I-94/I-69 overpasses at the Lapeer connector and Water Street; and a 15-foot-wide nonmotorized pathway across the Black River Bridge. The project begins in March and will be completed in November 2012.

Mobility Improvements:

• The new configuration of westbound I-94/I-69 over the Black River will include three lanes of traffic and direct access to Water Street and the Lapeer connector.
• The new configuration of eastbound I-94/I-69 over the Black River will include two lanes dedicated to Blue Water Bridge traffic and three lanes dedicated to local traffic (ending at Pine Grove Avenue).
• New access to westbound I-94/I-69 from the Lapeer connector and new access to the southbound Lapeer connector from eastbound I-94/I-69.
• Increased capacity on I-94/I-69 over the Black River.
• Widening of the existing Lapeer Road and Water Street overpasses above I-94/I-69.

Project Schedule:

• Construct the new eastbound lanes dedicated to local I-94/I-69 bridge over the Black River.
• Build the new three-lane Water Street overpass.
• Close and demolish the Port Huron Welcome Center at Water Street. Capac Rest Area will serve as a temporary welcome center.

• Construct the new eastbound lanes dedicated to Blue Water Bridge traffic on the I-94/I-69 bridge over the Black River.
• Construct the new westbound lanes on the I-94/I-69 bridge over the Black River.
• Build the new Lapeer connector overpass above I-94/I-69.
