    HOV

    NOW OPEN (effective 10/24/2023)

    The High-Occupancy Vehicle (HOV) lanes were added as an additional inside lane in each direction on I-75 between 12 Mile Road and South Boulevard (approximately 14 miles) in Oakland, County. This is the first of its kind in Michigan!

    HOV lanes require at least two human occupants inside the vehicle when used on weekdays between 6-9 AM and 3-6 PM. The exception is motorcycles, transit buses and police and emergency vehicles. Outside of those designated weekday hours the lanes are available for all motorists regardless of the number of occupants.

    State and local police will monitor safe movement in and out of the HOV lane and to ensure drivers have the correct number of people. Civil infractions will be handed out to violators.

    I-75 from I-696 to North of 13 Mile Road Flyover – November 2023

    In the latest flyover, you get a great view of I-75 between I-696 and 13 Mile Road now that the major roadway reconstruction is complete. In this video, you can see the I-75/I-696 interchange with the newly built braided ramps, the new Gardenia Avenue movement to Stephenson Highway, and the reopened 12 Mile Road diverging diamond interchange.   

    In addition, you get a peek at the newly opened high-occupancy vehicle (HOV) lanes that start just north of 12 Mile Road. Also shown are the overhead signs, the thicker lane markings, and the diamond pavement markings.    

    HOV lanes fast facts:   

    • HOV lanes hours of operation are Monday – Friday, 6 - 9 a.m. and 3 - 6 p.m.   
    • Vehicles with two or more people may use the HOV lanes during hours of operation.   
    • All vehicles regardless of the number of occupants can use the HOV lanes during off-peak operations.   
    • Motorcycles, buses, and emergency response vehicles can use the HOV lanes at any time.    
    • HOV lanes were built from 12 Mile Road to South Boulevard and an additional general purpose travel lane was built from M-102 (8 Mile Road) to 12 Mile Road.

    Carpool Lots Available!

    Did you know that carpool lots are available in multiple places along the I-75 Modernization Project corridor? Three lots are open: one at Adams Road and two at 12 Mile Road. Motorists are encouraged to utilize these lots or other existing MDOT lots to carpool to your destinations. Carpoolers using I-75 between 12 Mile Road and South Boulevard Monday through Friday, between 6 a.m. to 9 a.m. or 3 p.m. to 6 p.m., will also be able to utilize the High-Occupancy Vehicle (HOV) lanes during this time!

    HOV Lanes Enforcement

    With the High-Occupancy Vehicle (HOV) lanes now open along I-75 in Oakland County, it is important to know that both state and local police will monitor for safe movement in and out of the HOV lane and to ensure drivers have the correct number of occupants.

    Drivers signaled by police to pull over should not stop in the HOV lane, rather they should continue at safe speed and pull over as directed by the police.

    HOV Lane Facts:

    • HOV Lanes are located on I-75 between 12 Mile Road and South Boulevard
    • HOV lanes will operate Monday through Friday, from 6 a.m. to 9 a.m. and 3 p.m. to 6 p.m.
    • During those times, HOV lanes are open to motorists with 2 or more occupants, or those driving on a motorcycle.
    • Outside of those hours, all motorists are welcome to use this additional lane.

    Take a look at our video for more information on who can use the lanes, how to enter/exit them, and what to do if you are signaled to pull over.

    Drainage Tunnel Preparing to Accept Water

    Now that the tunnel boring machine (TBM) reached the Meyers Avenue Pump Station and is being removed from the ground, crews will begin completing work on the drop shafts throughout the corridor and finalize the tunnel drainage system so it can begin accepting water.      

    We have put together this graphic to show what will happen when rain hits the roadway and makes its way to and through the drainage tunnel. It is important to emphasize that the tunnel is not yet accepting water, as work to finalize the tunnel and pump station will continue throughout 2023.
