It's an election year and everybody is still mad at DeWine over the lockdowns and the masks. Based on the write up of what happened the last time around, that might have something to do with this. Nevertheless, it needs to be done at least from Columbus to Toledo and if they don't do it now, it will just be more expensive and unaffordable later.
I don't mind C1, but I don't see them tearing through parkland and putting a freeway along a scenic river. The natural connection is to Route 315 and there is a certain beauty about it.
The best/cheapest route is still US 23, with a bypass connecting you to US 36, and then freeway US 36 to I-71.
