There will be new weekend lane and ramp closures on I-75 in northern Oakland County for culvert replacement work between Saginaw/Dixie and Belford Road, which began Friday morning.

• There will be only one lane open on southbound I-75 from Baldwin Road to Belford Road.

• The southbound Saginaw-Dixie ramp to southbound I-75 will be closed. The detour is southbound Dixie Highway to northbound M-15 to access southbound I-75.

These ramp and lane closures will end at 5 a.m. Monday, April 28, according to a release from the Michigan Department of Transportation.

The work is part of a $160 million project to resurface and repair the expressway from M-15 to the Oakland/Genesee county line.

The project includes resurfacing I-75, repairing 11 bridges, drainage improvements, culvert replacements and new signs and guardrails.

This year, southbound I-75 will be milled and resurfaced from M-15 to the county line, with two lanes of northbound and southbound traffic sharing the northbound side of the freeway.

Bridge repairs will be performed throughout the project limits along southbound I-75. Work is expected to be completed for the year in late fall.

In 2026, crews will remove the temporary crossovers and perform remaining miscellaneous tasks.
