ST. IGNACE, Mich. – The first phase of a two-month construction project on the Mackinac Bridge is expected to cause some delays for travelers.
The Mackinac Bridge Authority (MBA) will begin a two-season repaving project on the bridge’s north viaduct and approach truss spans March 25, weather permitting.

Repaving, deck repairs, and joint repairs on the two northbound lanes of the bridge will begin March 25 and is scheduled to be completed by May 23. Traffic will be maintained with one lane open in each direction during construction. All lane closures will be lifted after May 23.
Weekend traffic peaks between 10 a.m. and 4 p.m., often resulting in traffic backups, even with all toll lanes open. Drivers should consider crossing at off-peak times or prepare for delays.
Wide-load restrictions will be in place in both directions for any vehicles wider than 10 feet during construction. Wider loads will be allowed to cross once per day between 7 and 8 p.m. Monday through Thursday, and traffic will be stopped for brief periods for those crossings.
Work will resume in late March 2025 with repaving of the two southbound lanes. The overall project is scheduled to be completed, with all lanes reopened, by May 22, 2025.
