Michigan Statewide Tolling Study

Feasibility Analysis and Strategic Implementation Plan

Key study findings

The Feasibility Analysis report includes an analysis of tolling 1,922 miles of limited-access highways in Michigan and includes a screening process to determine appropriate corridors for a more detailed study in the Strategic Implementation Plan report. The corridors studied in this Strategic Implementation Plan include nearly 550 miles and are made up of parts or all of I-69, I-75, I-94, I-196, I-275, I-696, and M-14.

Funding and Program Cost

A new statewide tolling program in Michigan could generate enough revenue to fully fund the life-cycle costs of the tolled roadways, but would require a careful approach to implementation. Total program costs including road work, bridge work, and toll systems from 2026 to 2031 are $8.5 billion, which would be funded by toll revenue bonds. After 2031, toll revenue would fund all ongoing construction, operations, and maintenance in addition to debt service on bonds.

Tolling Implementation

For the analysis, the toll system is assumed to be implemented over five years beginning in 2028. Shown below is the timeline when tolling could begin and the total system mileage by year for implementation.

Governance and Policy Recommendations

Along with the toll corridor analysis, the study included governance and policy recommendations to successfully implement a toll system.
  • A “hybrid” governance model like the Mackinac Bridge Authority.
  • Independent toll rate-setting authority, the ability to sell its bonds and procure it's toll-specific systems while still sharing staff and resources with MDOT.
  • The ability to hire necessary tolling-specific leadership and staff as new agency staff/consultants at industry-competitive salary levels should be further evaluated.
  • Incorporate tolling at a programmatic level into existing planning processes.
  • Perform project-level environmental clearance as required based on project characteristics.
