    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.

    Fast facts: 

    • The northbound I-75 ramps to eastbound and westbound I-696 will be closed for pavement and barrier wall repair.    
    • The ramp closures begin at Noon Friday, Sept. 10. 
    • Weather permitting, this work is expected to be completed by Oct. 1.  

    Pavement and barrier wall repair will begin Friday afternoon on the northbound I-75 ramps to eastbound and westbound I-696. The ramps will close at Noon Friday, Sept. 10, and will reopen Oct. 1, weather permitting.

    Did you know: Coolidge Highway Overpass was Lengthened to Accommodate Future Troy Mobility

    During reconstruction of I-75, crews lengthened the bridge over Coolidge Highway for the potential future City of Troy enhancements on this local roadway.  This bridge lengthening also allowed the right turn lane to be extended on northbound Coolidge Highway to safely queue more vehicles to turn, which improved operations and safety at the Coolidge/Square Lake Road signalized intersection north of the overpass.
