Motorists in Flint should gear up for significant changes as the I-475 construction project enters a new phase next week. According to the Michigan Department of Transportation (MDOT), ABC12 reports a major milestone with traffic switching sides starting on Wednesday. The shift is part of a two-year, $141 million initiative focused on rebuilding 3 miles of the vital roadway from the Flint River to Carpenter Road.

Specifically, MDOT will close the singular southbound lane that has remained open, and beginning 10 a.m. on December 14, one northbound lane will reopen, this, according to an MDOT announcement. Motorists should expect the southbound lanes to stay closed until September 2025 and utilise detours via I-69 and I-75 during reconstruction.

Anchoring the renovation is the construction of a new bridge over the Flint River along with improvements to other structures within the corridor. The work falls under Governor Gretchen Whitmer's Rebuilding Michigan program, which aims to repair critical highways and bridges that underpin the state's economic flow. MDOT has factored the work to ensure both longevity in infrastructure and an uplift in current conditions.

Data from MDOT hints at a positive economic impact, with the I-475 project expected to support approximately 1,706 jobs, both directly, and indirectly. Beyond economic stimulus, the focus of this undertaking is said to enhance mobility and increase safety for travelers navigating the I-475 terrain. A total closure from December 11 to 14 will facilitate a secure transition for workers and drivers alike as they toggle from the northbound to the southbound side.

This initiative is not just about refurbishing tarmac, it interweaves with the larger tapestry of MDOT's commitment to Michigan's infrastructure. Looking forward, MDOT is plotting a heftier $300 million rework for I-475, tackling the stretch south of the current zone with heavy construction penciled in for 2026 and 2027.
