    Big Beaver and 14 Mile Road DDI Updates (4/13/2021)

    The Big Beaver Road DDI is progressing as crews have restrictions in place to install the ADA ramps for pedestrians within the interchange.  Once complete, the interchange will be safer for all!   

    The left lane of eastbound and westbound 14 Mile Road will remain closed east of I-75 through mid-summer as crews await equipment arrival to complete the required signal installation and open all lanes.  

    DDI’s are a safer option for both motorists and pedestrians. To learn more about DDI’s including how to navigate them please visit our Project Highlights - DDI Edition page under “Travel I-75”.   Stay up-to-date with information about the project by signing for email blasts or following our social media channels.

    Tunnel Update – July 2021

    Currently under construction, one of the major aspects of the I-75 Modernization project is the 4-mile long drainage tunnel.  This tunnel is 100 feet underground and will run along I-75’s northbound service drive between 8 Mile and 12 Mile Roads.  This tunnel will provide storage and conveyance to help avoid future flooding in the depressed portion of the freeway.  Stormwater collected in the tunnel will be screened to remove debris and allow the water to flow to treatment facilities. These facilities will provide treatment and additional screening to ensure the discharged water is safe for the public. 

    Building of the tunnel began in the Fall of 2019 and is scheduled to continue through 2022.  The Tunnel Boring Machine (TBM), named Eliza, was launched last year and has now traveled over 6,205-feet north from the I-696 Shaft Site (northeast corner of the I-75/I-696 interchange), placing her near Farnum Avenue and the northbound service drive intersection.   For more information on Eliza and the need/benefits of the drainage tunnel please visit our Project Highlights page  http://modernize75.com/Project-Highlights-Tunnel.

    Talking Michigan Transportation Podcast – Reopening a major freeway after a tanker fire

    There are many questions regarding what goes into the reopening of a freeway following a tanker fire.  On the recent episode of the “Talking Michigan Transportation” podcast, you can hear more about the coordination efforts involved, process for cleanup, and how MDOT was able to quickly mobilize a crew to begin repairs on I-75 at Big Beaver Road following the fire on July 12th.

    Entrance Ramps to I-75 have Reopened following tanker fire

    We are pleased to say that crews have been able to reopen the ramps from 14 Mile Road to Northbound I-75 and the ramp from Crooks Road/Corporate Drive to Southbound I-75 following the tanker fire last week.  The ramps from Rochester Road to Northbound I-75 and Big Beaver to Southbound I-75 remain closed.

    11 Mile Demo Time Lapse Video – July 2021

    The weekend of July 9-11th, I-75 was closed as crews worked to demolish the 11 Mile Road Bridge. In this time lapse video you can see as crews begin staging for the work on Friday, then remove the concrete and beams, and conduct cleanup before reopening the freeway to traffic on Sunday.  Once the roadway was reopened, crews began working on excavating the pier in the median and the service drive slope as they continue to make progress on the removal of the structure.

    Repairs to damaged I-75 pavement at Big Beaver Road in Troy estimated at $1.5 million after tanker crash and fire

    Fast facts:

    • The July 12 tanker crash and fire resulted in significant damage to the freeway pavement and median barrier wall.
    • The estimated cost to rebuild sections of I-75 lanes and wall is estimated at $1.5 million.    
    • The repairs are anticipated to last six weeks.   

    The Michigan Department of Transportation (MDOT) announced that repairs to the damaged section of I-75 at Big Beaver Road in Troy is estimated at $1.5 million. All lanes of the freeway and a portion of the median barrier wall were damaged due to a July 12 tanker crash and fire. Those sections of pavement and barrier will be rebuilt, and all costs associated with the incident response, cleanup and repair will be submitted to the carrier's insurance company for reimbursement.    

    Currently, I-75 traffic is maintained in the right lane of each direction to allow traffic to move on the freeway while crews rebuild the damaged left lanes, along with the concrete median wall that separates both directions of traffic. Afterward, crews will move to rebuild the right lanes. To minimize expected delays, crews will keep closed the entrance ramps at 14 Mile and Rochester roads to northbound I-75, and the entrance ramps at Crooks Road/Corporate Drive and Big Beaver Road entrance ramps to southbound I-75.

    All lanes and ramps are expected to be reopened in six weeks.
