    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!   

    Beginning at 7 a.m. Friday, April 16 and ending at 5 p.m. Monday, April 19, crews will close 14 Mile Road under I-75, and all ramps at the interchange. This closure is needed to allow crews to safely place all 14 Mile Road traffic into its new configuration and open all ramp movements from I-75. Upon opening, 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.

    Did You Know: "Brass In, Brass Out" Safety Moment

    A Brass In, Brass Out board tells how many people are in the tunnel, should there be a safety issue. As crew members arrive to the tunnel, they move their assigned “Brass” from the “Out” position, to the “In” position.  This helps the site safety team know how many people are in the tunnel at any given time and allows for the team to monitor for crew limits based on space.

    Eliza Update – May 2021

    Eliza (the tunnel boring machine) remains hard at work underground, heading north towards 12 Mile Road. Eliza has now traveled over 2,700-feet north from the I-696 Shaft Site (northeast corner of the I-75/I-696 interchange), placing her near Cowan Avenue and the northbound service drive intersection.   So far, 549 “rings” of 5-foot long precast concrete tunnel linings have been installed There have been 3,294 individual precast concrete segments installed.  You can see them all bolted together in the picture below.  For more information on Eliza and the drainage tunnel please visit our Project Highlights page   http://modernize75.com/Project-Highlights-Tunnel.    

    precast segments installed, as well as the temporary rail line and construction utilities

    Shevlin Time Lapse for Beam Setting April 2021

    Crews have been busy rebuilding the Shevlin Avenue Bridge. After the bridge was demolished at the end of February, crews have been working on the base and foundation so the new beams could be set.  Check out the time lapse video from April 9th-14th for a peak into the process of beam setting.  The beams over northbound I-75 were set while the freeway was closed earlier this month, while the beams over southbound were able to be set while the freeway was open since all traffic is maintained on the northbound side of the freeway.
