Long-term I-75 South Detours in Metro Detroit Kick in Feb 4th


Carriers are reminded that long-term construction work will commence February 4 in the Metro Detroit area which will see the southbound lanes of I-75 closed from I-96 to Sibley Road. The northbound lanes of I-75 are not be affected by this construction effort, which is expected to continue for up to two years.

This closure is part of the Michigan Department of Transportation’s (MDOT) approximately $200 million investment in major repairs and bridge replacements over a two-year period for this key stretch of I-75.

Several detours will be in place to facilitate truck traffic around the construction area. However, traffic delays are expected as motorists and commercial traffic adjust to the closures.

The main detour for traffic coming from north of the city is southbound I-75 to westbound I-96, then southbound I-275 to southbound I-75 in Monroe. However, there are alternate routes for trucks crossing into Detroit at the Ambassador Bridge, which include I-94, M-85 (Fort Street), Jefferson Avenue, and Dix Highway. In all cases travel times and distances will increase over the normal route used by traffic along southbound I-75.

Variable message signs indicating travel times on the various detour routes have been installed by the Michigan Department of Transportation (MDOT) to assist drivers in making informed decisions about which detours to take.

Officials from both MDOT and the Ambassador Bridge will be monitoring the traffic situations throughout the construction period and will make necessary adjustments if needed to facilitate traffic flow.
