    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.

    Vegetation planting begins October 23 on I-75 in Oakland County 

    Weather permitting, landscaping crews will begin vegetation planting along I-75 in Oakland County during the months of October, November, and December. For healthy planting sustainability, additional work will take place in the spring. The plantings will occur approximately along the 8-mile stretch of I-75 between Coolidge Highway and 14 Mile Rd. The plantings are part of the freeway modernization project that reconstructed a section of I-75 during the 2019 and 2020 construction seasons. In order to safely unload equipment and vegetation, there will be intermittent shoulder and single-lane closures along northbound and southbound I-75 during non-peak travel hours.

    Stephenson Highway Reconfiguration

    Stephenson Highway bridge over I-75 was demolished in mid-September and will not be replaced. The I-75 Modernization project will rebuild and convert Stephenson Highway to handle two-way traffic north of Gardenia Avenue. Once complete, the northbound I-75 service drive traffic will 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. This work is currently scheduled to be completed during the 2022 construction season in conjunction with the replacement of the Gardenia Avenue bridge.  The ultimate configuration of the Gardenia Avenue bridge and Stephenson Highway in this area can be found at the following link  https://www.modernize75.com/media/zpciqqbk/gardenia-avenue-bridge-reconfiguration-to-accommodate-northbound-stephenson-highway.pdf
