    Attention residents of the City of Troy and motorists who use the Big Beaver or 14 Mile Road Interchanges:

    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.

    Did you know: Tunnel Edition  

    Once completed, how does the Drainage and Storage Tunnel work?  

    Storm water is collected from the I-75 freeway and service drives in a network of pipes that direct flows into seven “drop shafts” (large pipes).  These shafts connect to the tunnel below, where the storm water then flows north to a new pump station just northeast of the I-75 and 12 Mile Road interchange.  The pump station lifts the water nearly 100-feet and discharges it into the Oakland County Water Resources Commissioner (OCWRC) Retention Treatment Facility.    

    For more information on the drainage tunnel please visit our Project Highlights page   http://modernize75.com/Project-Highlights-Tunnel.

    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.
