And even if you didn't spend money on the not-very-compelling widening of I-94, the bridges would still need a lot of rebuilding, which would still cost a lot. We should complain about the mix of transportation spending in Michigan, but if Michigan devoted all of its current transportation spending to road maintenance, it would still be wouldn't be spending enough just on that.
If I were emperor I would probably opt to convert I-94 to an at-grade parkway through the city and completely do away with the need for bridges and the associated maintenance costs. I would route I-94 up I-275 and over I-696 to join up with its current route towards Port Huron north of the city.
