MDOT Alert: Temporary Bridge Support installation on I-75 under I-94 in Detroit

DETROIT, MI – The Michigan Department of Transportation (MDOT) will be installing 10 temporary MDOTbridge supports on northbound and southbound I-75 under the eastbound I-94 ramp after routine bridge maintenance discovered deteriorated concrete on one of the supporting columns.

The temporary supports will stabilize the bridge, keeping it safe to travel through this interchange while MDOT does further evaluation.

MDOT typically spends $10 million per year on temporary bridge supports, emergency repairs and preventive maintenance, and that dollar amount is growing due to deteriorating statewide bridge conditions. “Without new investment, motorists will only see more temporary supports and plywood to support our aging bridges,” said MDOT Director Kirk T. Steudle. “We can only be thankful that our robust inspection process works, and our dedicated bridge engineers are passionate about public safety.”


The left lane of both northbound and southbound I-75 will be closed to allow for the installation of a concrete barrier to protect construction crews working under the bridge near heavy traffic. Motorists can expect occasional closures of the second left lane during non-peak hours in order to provide workers additional room to work safely.

Following installation of the temporary bridge supports, the left shoulders of northbound and southbound I-75 will remain closed.

START DATE: Wednesday, March 11, 2015  After 9 a.m. These temporary repairs could take a week.
