Detroit — The Michigan Department of Transportation has closed some of the ramps from Interstate 75 to the Lodge Freeway (M-10).
The northbound ramp to the northbound Lodge could be closed for up to a week, while the southbound ramp to southbound Lodge is closed through Wednesday morning, MDOT spokeswoman Diane Cross said. The right lane of south M-10 under the I-75 ramps also is closed for the repair crews through Wednesday.
According to MDOT, bridge inspectors Monday discovered two of the four support steel beams were weakened due to rust.
“It’s right at northbound I-75 where M-10 splits,” Cross said. “They discovered a number of safety issues and closed the (NB I-75 ramp to NB M-10) right away. It will be closed to get a good look at the situation, and we will be putting in supports in the meantime.”
The detour is NB I-75 to WB I-94 to NB M-10.
Cross said there was no absolute way to know if the NB ramp would have collapsed.
“But at the same time, we’re talking about half the support beams being rusted out,” Cross said. “This is a perfect example of our aging infrastructure. If we don’t have enough money to fix the problems, we’re going to end up eventually closing roads.
“But we will come up with money to repair this ramp.”
In Lansing, the state Senate debated whether to increase the amount of spending in a House-passed $450 million road funding package that heavily relies on shifting around existing state tax dollars to make it “revenue neutral.”
The Senate Infrastructure Modernization Committee was scheduled to take testimony Tuesday on the House bills.
