Being very honest , I like the proposal of I-73. I just think it's in the wrong place. The US 23 corridor through the entire state of Ohio really should be I-73 and yes, I have been on it. The thing that I'm not so sure is about the US 52 corridor in West Virginia ; does it have the traffic on that stretch to qualify I-73/I-74 being built on it.
And I definitely don't like I-74 being it's dancing partner either. To me, it makes more sense for I-74 to follow US 50 from Ohio to Virginia and take over I-66 . Therefore I-66 in Kentucky would make more sense. To me, the roads that have the most controversy are I-97, I-99, I-73, and the extended I-74.
I think Michigan & Ohio would have liked to have I-73 (except the people on US 223) but both states are not too sure where the funding is going to come from and that's why they rejected it. It's too bad I-73 could not follow US 23 down the east side of Kentucky and go to Atlanta; then follow US 19 down to the Suncoast Pkwy and end in Tampa instead of Myrtle Beach. And then let I-74 be extended to Myrtle Beach by its lonesome. I think the US Congress messed up completely on I-73.
