I-75 Coolidge Highway to Big Beaver Road - Nov 2020
Good weather in early November allowed for some great flyover footage throughout the project. In this video, check out the Coolidge Highway to Big Beaver Road section showing the great progress made so far this year. While there is more work to be done, we are happy to continue to share these flyover videos.
As crews are wrapping up work throughout the project for the winter, there is still much that will continue. Work to complete the Diverging Diamond Interchanges (DDI) at Big Beaver and 14 Mile Roads has made a lot of progress, however Big Beaver DDI is looking to fully open in mid-December 2020 and the 14 Mile Road DDI is looking to fully open in Spring 2021. Please see below for an update on each location:read more
14 Mile Road closed under I-75 for interchange construction starting Monday
Interchange construction will require the closure of 14 Mile Road under I-75 next week in the city of Troy. Starting at 9 a.m. Monday, Nov. 9, through-traffic on 14 Mile Road will be detoured continuously until 6 p.m. Sunday, Nov. 15. Posted detours will include John R. Road, Maple Road, and Stephenson Highway in both directions. Access will be maintained to Oakland Mall during the week.
The closure is needed for crews to pave and apply final striping to 14 Mile Road in conjunction with the new diverging diamond interchange design.
In addition, single-lane closures will occur on northbound I-75 from 13 Mile to 14 Mile roads daily starting at 9 a.m. and ending by 3 p.m. Monday through Thursday. The left lane will be closed Monday, Nov. 9, and Tuesday, Nov. 10. The right lane will be closed Wednesday, Nov. 11, and Thursday, Nov. 12. This work is weather dependent; any precipitation will push the closures back one day.
A portion of northbound I-75 to have one lane open Wednesday and Thursday in Oakland County
MDOT contracting crews will be installing pavement markings this week. This work will require reducing northbound I-75 to only one open lane from 12 Mile to Adams roads continuously starting at 9 a.m. Wednesday, Nov. 4, and ending at 6 p.m. Thursday, Nov. 5. As the application process continues, there may be short-term closures of northbound I-75 exit and entrance ramps. This work is weather dependent, and any form of precipitation will push back the lane opening by one day.
