MDOT: Wrong Concrete Mix Used On Portions Of Northbound I-75 Lanes In Oakland County
Due to this discovery, contractor paving crews will remove and replace those affected portions before all paving is completed in late 2020.

DETROIT (CBS) — Michigan Department of Transportation inspection teams working on Segment 2 of the I-75 modernization project in Oakland County discovered the incorrect concrete mix was used recently on portions of the project, including the left two lanes of northbound I-75 from 13 1/2 Mile to 14 Mile roads, and the shoulders on the exit ramps to Big Beaver and Rochester roads.
Due to this discovery, contractor paving crews will remove and replace those affected portions before all paving is completed in late 2020. Currently, both directions of I-75 are sharing the southbound side of the freeway, separated by a temporary concrete barrier between 13 Mile Road and Coolidge Highway. Two lanes are open in each direction.
