I-75 Corridor Study

I-75 Corridor Study

About the study

The I-75 corridor plan is a study that evaluated future needs and developed strategies for I-75 from Square Lake Road to US-23 in Oakland and Genesee counties. Throughout the study, MDOT and community partners identified long-term operational needs, evaluated transit and nonmotorized opportunities, and developed recommendations for short-, mid-, and long-term strategies. These recommendations will enable MDOT to better coordinate the future direction of I-75. 

One main goal of the study was to develop a vibrant multimodal corridor that aligns with the vision and strategies of the Michigan Mobility 2045 Plan (MM2045).

Recommendations

Some recommendations from the study include:

  • Develop strategies to improve safety and nonmotorized access at interchanges throughout the corridor.
  • Develop and study alternatives for the I-75/M-59 interchange to improve operations and safety.
  • Implement adaptive signal control timing, which uses technology to help improve traffic flow at M-1 (Woodward Avenue) and I-75 Business Loop.
  • Further study M-15 from I-75 to Ortonville Road to identify strategies to improve traffic flow.
  • Develop alternatives to improve traffic flow at the I-75/Grange Hall Road interchange.

Each recommendation went through a high-level economic analysis where safety, operations and maintenance costs and other factors were considered. Detailed information can be found in the report.
