    Post-holiday lane and ramp closures begin Tuesday, Sept. 5, on I-75 modernization project in Oakland County

    Fast facts: 

    • Starting at noon Tuesday, Sept. 5, the northbound I-75 right lane from Gardenia Avenue to 12 Mile Road and the I-75 exit ramp to 12 Mile Road will be closed for sound wall installation.  
    • Starting at 5 a.m. Monday, Sept. 11, the eastbound and westbound I-696 ramps to northbound I-75 will be closed for pavement and barrier wall repair. 
    • Starting at 5 a.m. Monday, Sept. 11, the southbound I-75 right lane will be closed for pavement repair from I-696 to 9 Mile Road.               

    Weather permitting, contract crews will resume work on a portion of the I-75 modernization project in Oakland County. By noon Tuesday, Sept. 5, the northbound I-75 right lane will be closed from Gardenia Avenue to 12 Mile Road for sound wall installation. In addition, the northbound I-75 exit ramp to 12 Mile Road will be closed. The lane and ramp closures will be removed by the end of September.  

    Also starting Tuesday, Sept. 5, the southbound I-75 service drive will be closed from south of 9 Mile Road to Meyers Avenue until late November.  

    Starting at 5 a.m. Monday, Sept. 11, the eastbound and westbound I-696 ramps to northbound I-75 will be closed. The ramp closures are needed to allow crews to safely repair the section of pavement and barrier wall damaged by the tanker crash on Aug. 4. In addition, the southbound I-75 right lane will be closed from I-696 to 9 Mile Road for pavement repair from a June 20 vehicle fire. The lane and ramp closures are expected to end by Saturday, Oct. 7.

    Stephenson Highway north of Gardenia Avenue is now OPEN! 

    The Gardenia Avenue Bridge was demolished in early 2022 to make way for a wider, more accommodating bridge that integrates the turning movement previously provided by the Stephenson Highway Crossover that was eliminated in 2021.   

    This new wider bridge allows the northbound I-75 service drive traffic to turn left (to head west) at Gardenia Avenue and cross over I-75 and then turn right (to head north) at Stephenson Highway on the new two-way section toward 12 Mile Road.  In addition, this new two way section of Stephenson Highway will accommodate pedestrians on both the east and west sides, providing easy access to and from the Bellaire Avenue Pedestrian Bridge that was replaced in 2021.    

    A visual rendering of this new configuration is available on our website under Segment 3 Resources:

    11 Mile Road to and from Southbound I-75 has Reopened!

    We are happy to announce the reopening of the 11 Mile Road ramps to and from southbound I-75. The reconstruction of this ramp started in late 2022 and has now reopened for use. 

    During reconstruction the ramp was relocated approximately 400-feet north to allow for safer merging of traffic. This will allow those entering I-75 and those needing to exit to I-696 additional weave room for safer lane changes.  

    Stay tuned for more updates as we continue reopening the roadway.

    12 Mile Road and the ramps to and from Southbound I-75 have Reopened!

    We are happy to announce the reopening of 12 Mile Road as well as the ramps to and from southbound I-75.  As part of the I-75 Modernization Project this interchange was reconstructed into a diverging diamond interchange (DDI).  This design improves safety and mobility through the interchange. For more about DDIs and how they work, please visit our website: http://modernize75.com/Project-Highlights-DDI 

    Stay tuned for more updates as we continue reopening the roadway and ramps.

    I-75 South of I-696 to North of 13 Mile Road Flyover – August 2023

    In the latest flyover, you get a great sneak peek at the progress of the project between I-696 and 13 Mile Road.  Teams are working hard to get elements of the project wrapped up ahead of opening the roadway and ramps prior to the 2023 Labor Day weekend.    

    Take a look at the progress of the 11 Mile Road ramps to and from southbound I-75, the new two-way service drive north of Gardenia Avenue, and progress at the 12 Mile Road diverging diamond interchange, to name a few items. 

    In addition, you can see the damage to the roadway just north of Lincoln Avenue where there was a tanker crash in early August.  Crews will begin repairs of that area following the holiday weekend.

    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.
