Port Huron, MI – Drivers in St. Clair County should prepare for lane closures along I-69 starting Monday, Oct. 20, as the Michigan Department of Transportation (MDOT) begins bridge maintenance on Allen Road over I-69.
According to MDOT, the project is necessary after crews discovered a crack in one of the bridge beams during repainting earlier this summer. The repairs will require a closure of one westbound lane on I-69 for the duration of the work, which is expected to continue through Friday, Nov. 7, 2025.
During construction, one alternating lane of traffic will remain open on Allen Road, maintained via a portable traffic signal to manage vehicle flow safely.
MDOT officials said the work is intended to ensure the long-term safety and reliability of the bridge. “Closing lanes on I-69 and Allen Road is necessary to allow crews to safely perform the work,” the department stated in a release.
Drivers traveling through the Port Huron area should anticipate minor delays and are encouraged to plan alternate routes or allow extra travel time during the three-week project.
