Kim Nowack, Bridge Director of the MBA, reported today that 502,868 vehicles crossed the Mackinac Bridge during the month of September compared to 498,563 in 2023.
For the month of September, traffic was up 0.9% and toll revenue was up 1.2% compared to last year.
The Mackinac Bridge Authority has scheduled a substantial amount of long-term preservation work for the bridge over the next several years. These major efforts will ensure that the bridge continues to remain structurally sound and provide a safe crossing for everyone.
The MBA’s sole source of funding is from tolls and fees collected at the Mackinac Bridge. All revenue collected is used to maintain, operate, and protect the 67-year-old National Historic Civil Engineering Landmark.
