What this leaves us with, is no major highway running from the South-East (West Virginia) towards the North-West (Toledo, Detroit).
Do we need another highway running through Columbus? Well, I-73 has been on the drawing board for over a decade and could eventually become a reality. It’s planned to reach from Myrtle Beach all the way up to the Upper Peninsula of Michigan. Currently the only existing stretch is 26 miles of highway in North Carolina.
According to Wikipedia:
In Ohio, I-73 was planned to parallel U.S. Route 52 to Portsmouth, where it would split with I-74, and U.S. Route 23 the rest of the way through Columbus to Toledo and the Michigan state line. The part from Portsmouth to Columbus is Corridor C of the Appalachian Development Highway System. Ohio has abandoned further study of the I-73 corridor, since much of the US-23/US-52 corridor is scheduled to be upgraded to freeway status under separate projects. Nonetheless, the option to designate the corridor as I-73 once all upgrades are complete remains open, contingent upon what happens with the route in West Virginia.
I’ve not heard anything from ODOT for a long time on this project, but it’s always something to keep an eye on.
