The US-127 corridor running through Ingham and Clinton counties will cost more than $400 million to rebuild, with the federal government covering roughly a third of the tab, according to the nation's top highway official.

Federal Highway Administration (FHWA) Administrator Sean McMaster toured the project Thursday, Aug. 27, alongside Michigan Department of Transportation (MDOT) officials. The visit gave McMaster a close look at the active construction zone between Lake Lansing Road and I-69.

"Right now, to date, this project will be a little bit north of $400 million all in," McMaster told WILX. "About a third of that, roughly, a little under that, will be federal assistance."

The road is about 50 years old and had reached the end of its life cycle, McMaster said.

Work on the corridor began in late 2022 with resurfacing south of the Lansing area near the Jackson County line, according to the Lansing State Journal. A final phase rebuilding US-127 from I-496 to Lake Lansing Road is set to begin in spring 2027 and finish in fall 2028. The full corridor project is scheduled for completion in 2029.

For drivers navigating construction on the corridor, the City of East Lansing lists ongoing lane closures on US-127 and ramp closures at the Lake Lansing Road and I-69 interchanges. Southbound entrance ramps from Lake Lansing Road closed Aug. 14 as part of a traffic shift and are scheduled to remain closed through Oct. 3, according to WILX.

The project scope includes bridge rehabilitation, sound wall installation, pavement repairs, drainage upgrades, new signage and intelligent transportation system improvements, according to the city's construction notice.

MDOT shifted traffic onto the southbound side of US-127 between Lake Lansing Road and I-69 beginning April 28, according to an MDOT press release.

The next major milestone is the spring 2027 start of the final phase between I-496 and Lake Lansing Road. Residents can track closures and detours through the City of East Lansing's construction updates page.
