    • High-Occupancy Vehicle (HOV) lanes are now open. The left lane in each direction, between 12 Mile Road and South Boulevard, will now operate as an HOV lane Mondays through Fridays, from 6 a.m. to 9 a.m. and 3 p.m. to 6 p.m. Motorists with 2 or more occupants, or those driving on a motorcycle, can utilize this additional lane during these designated times. Outside of those hours, all motorists are welcome to use this lane without the risk of a violation. Learn more: www.modernize75.com/HOV

    Closures

    Segment 3

    Lanes/Ramps:

    • Weather dependent, crews will implement lane closures on I-75 between 9 Mile Road and Lincoln Avenue through Friday, Mar 8 as crews remove tunnel bulkheads in preparation for the Drainage Tunnel to begin accepting water.  Crews will shift the closure to the right or left lane based on work being done that day, however it is expected that no more than one lane on I-75 will be impacted at a time. This work will also require closure of the 9 Mile ramp to southbound I-75 during this time. 

    Service Drive:

      • Southbound service drive near Meyers Avenue will remain closed as crews work at the tunnel site.

    **Note, all work is weather dependent, and dates/times are subject to change.

    You can also use the interactive map on the MDOT MiDrive site (https://mdotjboss.state.mi.us/MiDrive/map) to see open/closed ramps. 

    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 Modernization Project Additional Lane

    The I-75 improvements between 8 Mile (M-102) and South Boulevard, north of Square Lake Road, include an additional inside lane, expanding the road to four lanes in each direction for improved safety, efficiency and reliability.   

    The extra lanes are for HOV use (High-Occupancy Vehicle) or as additional driving lane. 

    • NB/SB I-75, 12 Mile to South Boulevard:
      • HOV only - 6 a.m.-9 a.m. AND 3 p.m.-6 p.m.
      • Otherwise, general use
    • NB/SB I-75, 8 Mile to 12 Mile is always general use

    I-75 Full Flyover, M-102 (8 Mile Road) to South Boulevard – December 2023 (10 min)

    In December 2023, crews spent time flying a drone the entire length of the project, nearly 18 miles, to capture the completed work that began construction in 2016 and completed in 2023.  A few things you will see in this video:  

    • The rebuilt freeway lanes between 8 Mile Road and South Boulevard  
    • The rebuilt pedestrian bridges  
    • The reconfiguration of the I-75/I-696 interchange ramps using a braid design 
    • High-occupancy vehicle (HOV) lane signs and lane markings  
    • The new diverging diamond interchanges (DDIs) at 12 Mile, 14 Mile, and Big Beaver roads  
    • The rebuilt Gardenia Avenue bridge with new movement of motorists to Stephenson Highway  
    • So much more!  

    Thank you all for your continued patience on this project.

    HOV Lanes Enforcement

    With the High-Occupancy Vehicle (HOV) lanes operating 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.

    I-75/I-696 Braid Ramp Hyperlapse – December 2023

    The project team took advantage of warmer weather in December to capture this unique view of the I-75/I-696 interchange "braid" ramp opened at the end of 2022. This video, called a Hyperlapse, condenses a period of time into just a minute to show this ramp in action and showcases the volume of traffic that uses the interchange. 

    As a reminder, the reconfiguration of the I-75/I-696 interchange ramps using a braid design eliminated the weave that previously occurred by separating the movements. This reconfiguration allows I-696 motorists access to either northbound I-75 or 11 Mile Road using a new bridge, while the motorists exiting northbound I-75 to 11 Mile Road will braid under this new bridge to support a safer operation.

    Lane Closures on I-75 beginning Monday, Jan 22

    Weather dependent, crews will implement lane closures on I-75 between 9 Mile Road and Lincoln Avenue starting at 9 a.m. Monday, Jan. 22 through Friday, Jan. 26 as crews remove tunnel bulkheads in preparation for the Drainage Tunnel to begin accepting water.  Crews will shift the closure to the right or left lane based on work being done that day, however it is expected that no more than one lane on I-75 will be impacted at a time.  This work will also require closure of the 9 Mile ramp to southbound I-75 during this time.  Thank you for your continued patience.

    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!

    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.

    High-Occupancy Vehicle (HOV) lanes

    HOV lanes are opening along I-75 in Oakland County. These lanes, one running northbound and one running southbound on the inside lane, have been added to I-75 between 12 Mile Road and South Boulevard.

    When are the HOV lane hours of operation?

    The clearly marked left-hand lane opens for HOV travel only during peak weekday travel times. At all other times, the lane is open for general traffic with no restrictions.

    The HOV lane runs from 12 Mile Road to South Boulevard (approximately 14 miles):

    • Peak hour operations are 6-9 AM & 3-6 PM
    • Regular lane operations remaining hours

    Who can use the HOV lane?

    The HOV lane can be used by all vehicles with two or more people. Motorcycles are welcome in the HOV lane, too.

    How do I enter the HOV lane?

    To enter the HOV lane, check for oncoming traffic in the lane, signal, and enter the HOV lane at traffic-speed.

    How will the HOV lane rules be enforced?

    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 people.

    How will I know where the HOV lane starts and ends?

    Signage will be posted to warn of upcoming start or end of the HOV lane; with information on operating hours
