June 24, 2020 -- Progress is being made on the replacement of the southbound I-75 bridge over 14 Mile Road in the city of Troy. Weather permitting, crews will pour a new bridge deck on the structure that carries southbound I-75 over 14 Mile Road. This will require closing 14 Mile Road under I-75.

Starting at 8 p.m. Thursday, June 25, and ending by 9 a.m. Friday, June 26, both directions of 14 Mile Road will be closed directly under I-75. Posted detours use John R Road, Stephenson Highway, Maple Road, and Rochester Road in both directions.

The new bridge will be part of an innovative diverging diamond interchange (DDI) design that will be implemented at the I-75/14 Mile Road interchange. To expedite the completion of the DDI, crews will close exits at the interchange starting Friday.  

Beginning at 9 a.m. Friday, June 26, the northbound I-75 exit to 14 Mile Road will close until early September. Northbound traffic will be directed to exit at Rochester Road and use Big Beaver and John R roads back to 14 Mile Road.  

The southbound I-75 exit to 14 Mile Road is expected to close at 5 a.m. Saturday, June 27 and remain closed until the end of July. Southbound I-75 traffic will exit at Big Beaver Road and follow the posted detour that uses Crooks Road, Maple Road and Stephenson Highway.
