The Michigan Department of Transportation (MDOT) has announced an $8.9 million project to improve the I-94/M-39 (Southfield Freeway) interchange in Allen Park. The interchange, which dates back to the mid-1980s, serves about 20,000 vehicles daily.
The planned improvements include resurfacing the bridge surface, patching railings and beams, replacing bridge approaches, applying an epoxy overlay, and installing new bridge bearings under the southbound M-39 bridge over both directions of I-94.
Starting at 7 a.m. on Monday, September 29, most ramps connecting M-39 to I-94 will close through December for construction. The affected ramps are scheduled to reopen for winter before closing again in 2026 for additional work.
During this period:
- Southbound M-39 ramps to eastbound and westbound I-94 will be closed. Detours will route traffic via Exit 7 to eastbound M-153 (Ford Road)/McGraw Avenue and southbound Weir Street for eastbound I-94; or via Exit 7 to eastbound M-153 (Ford Road), then southbound Wyoming Avenue and westbound US-12 (Michigan Avenue) for westbound I-94.
- The northbound M-39 ramp to westbound I-94 will also be closed. Drivers are advised to continue north past I-94, take Exit 6 to eastbound US-12 (Michigan Avenue), then south on Greenfield Road to reach westbound I-94.
- Only one lane will remain open from eastbound I-94 onto northbound M-39.
According to MDOT, these detour routes were chosen based on factors such as ongoing construction on alternate roads and minimizing travel time through downtown areas.
In spring 2026, further closures are planned as part of a larger four-year project on I-94 stretching from east of I-275 to US-12 at the Dearborn/Detroit border. Thirteen additional bridges within the interchange will be improved during that phase.
Funding comes from Governor Gretchen Whitmer's Rebuilding Michigan program, which focuses on rebuilding key highways and bridges that support the state's economy by carrying significant traffic volumes. The program aims for long-lasting repairs that enhance Michigan’s infrastructure condition.
MDOT states: "Based on economic modeling, this $8.9 million investment is expected to directly and indirectly support 85 jobs."
