Travel I-75

Project Highlights - HOV Edition

What is an HOV Lane?

A High-Occupancy Vehicle (HOV) lane requires 2 or more passengers.

Why add HOV Lanes to I-75?

HOV lanes are an environmentally conscious choice to expand capacity on I-75, which:

  • Increase capacity for travel demand
  • Enhance personal mobility
  • Advance movement of freight/goods, supporting economic development
  • Improve safety, efficiency and reliability

What are the benefits of HOV Lanes on I-75?

HOV lanes will add capacity in the I-75 median, with one new lane in each direction.

  • Most “environmentally friendly” to alleviate congestion
  • Promotes carpooling for increased air quality

How will we know if HOV Lanes on I-75 are successful?*

  • Useage
  • Operation at 45mph or greater (approximately 90% of time)
  • Other lanes are less congested during operations

* requires time for motorists to acclimate, realize advantages and form carpools

How HOV Lanes will work on I-75? 

  • HOV Lanes will be in use only during peak-hour operations: 6 a.m. to 9 a.m and 3 p.m. to 6 p.m. Monday-Friday.
  • Vehicles with two or more people may use the HOV Lane during hours of operation.
  • HOV Lane will allow all users during off-peak operations.
  • HOV Lanes are planned for 12 Mile Road to South Boulevard and an additional travel lane is being built from M-102 (8 Mile Road) to 12 Mile Road.

When will the HOV Lane open?

Once Segment 2 is complete, an additional inside lane will be striped for HOV from north of 13 Mile Road to South Boulevard in the Fall 2020/Winter 2021, providing four lanes in each direction on I-75.

Once Segment 3 is complete, the final HOV mile will be signed and striped from 12 Mile to north of 13 Mile Roads providing the completed peak hour HOV lane from 12 Mile Road to north of South Boulevard in the Fall 2023, providing four lanes in each direction on I-75.
