I can't fathom them putting in a toll road, but who knows. They were supposed to have removed the one on 400 after it paid for the road. The road was paid for years ago, but they wont give up that tax money.
I heard on the news a couple of days ago that they are going to propose flexible lanes for I75. Meaning northbound lanes will accomadate southbound traffic in the mornings and visa versa in the evening.
