DEARBORN, Mich. - The Michigan Department of Transportation's (MDOT) Restore94 project to repair and rebuild I-94 between I-275 and US-12 (Michigan Avenue) at the Dearborn/Detroit border will resume with work beginning at the I-94/M-39 (Southfield Freeway) interchange in early March and continuing throughout the 2026 construction season.
Work at the I-94/M-39 interchange, which began last fall, will include resurfacing the ramp/bridge surfaces, railing and beam patching, bridge approach replacement, epoxy overlay and replacing bridge bearings. This interchange was originally built in the mid-1980s and carries approximately 20,000 vehicles a day.
During work, most of the I-94/M-39 interchange ramps will be closing, along with lane closures on M-39 and I-94.
Beginning 9 a.m. Monday, March 2 - Fall 2026:
Beginning 9 a.m. Friday, March 6 - Fall 2026:
These detours were selected due to a number of factors, including other construction happening on alternate roads, the distance of the detour route, driving through downtowns, etc., which would add more time to the detour route.
MDOT is investing $353 million along almost 13 miles of I-94 in Metro Detroit with a variety of work, including rebuilding and realigning the roadway, building a new interchange at Ecorse Road, concrete repairs/patching, bridge work, ramp work, lighting improvements, cable barrier work, improved drainage and intelligent transportation system upgrades.
Two lanes of I-94 are expected to be open in each direction between I-275 and US-12 (Michigan Avenue) for a majority of this multi-year project. However, drivers should expect many ramp closures.
More project information is available at Restore94.com.
