Dearborn, MI - The Michigan Department of Transportation (MDOT) is investing $12.7 million to repair six bridges near the M-39/US-12 interchange in Dearborn. This will include multiple lane closures on M-39 and US-12 and two full weekend closures of M-39.
The project is expected to start at 9 a.m. Monday March 2, 2020 and to be completed in the Fall of 2020.
The northbound and southbound M-39 service drives will have complete closures, including the southbound service drive closed for approximately two weeks and the northbound service drive for approximately three weeks.
M-39 (Southfield Freeway):
- Beginning Monday at 9 a.m., northbound and southbound M-39 will be reduced to one lane under US-12 through the fall.
- Beginning Tuesday at 9 a.m., the southbound M-39 service drive will be closed from US-12 to Rotunda Drive for approximately two weeks, then will reopen to one lane through the fall.
- Beginning Tuesday at 9 a.m., the northbound M-39 service drive will be reduced to one lane. At some point in April, the northbound M-39 service drive will close for approximately three weeks and will reopen to one lane. During that closure, the northbound M-39 ramp to US-12 will also be closed. The closure date will be announced at a later date.
US-12 (Michigan Avenue):
Beginning Monday at 9 a.m., eastbound and westbound US-12 over M-39 will have one lane closed in each direction to build crossovers in the median. In mid-March, bridge work will begin by reducing eastbound and westbound traffic from four lanes to two lanes and shifting this traffic onto one of the bridges while the other is repaired.
SAFETY BENEFIT:
The repair and replacement of these bridges will ensure safer routes for drivers through this very busy interchange that accommodates approximately 150,000 drivers daily.
