Looks like they're opting for a mostly new-terrain route. It would also be likely that US 219 would be moved to the new Thomas bypass and intersect Corridor H/US 48 near Davis and subsequently follow it all the way to north of Elkins, where it presently departs the corridor. But this alignment will entail a rather impressive bridge over Blackwater Gorge -- I'd certainly like to see any forthcoming plans for this structure. But the start date of 2031 is a bit discouraging if not unexpected, considering this corridor's history.
Agree that U.S. 219 should be on Corridor H as much as it possibly can be.
Given the massive structure that is under construction that will carry Corridor H over Haddix Run south of Parsons near the community of Moore, I do not think WVDOT is deterred by large bridges on this project (there are also several on the eastern segment).
I think a change in the balance of power in Washington might speed that 2031 date up by quite a bit. That is where the constraint is.
There's a decent amount of truck traffic on 219 between Parsons and Thomas now, and I'm sure truckers would appreciate a through route that takes them off that mountain. Looks like the new route will obliterate that route, but trucks still won't want to get off Corridor H there and go down to the stop sign at Thomas where they have to turn left at a T-intersection. And I'm sure the residents and businesses (many tourist-themed) in Thomas wouldn't want more heavy trucks rumbling down those one-way streets that turn much of the business district into an island in the asphalt. So the truck bypass is definitely warranted. I'm guessing a grade-separated interchange at what will be WV 32/US 48/US 219 (where WV 93 currently ends) and can't really tell, but an at-grade where WV 72 joins/departs at the foot of aforesaid mountain north of downtown Parsons.
I have read about a U.S. 219 "bypass" of Thomas before, but never seen it on a map until now. This is a good idea, as it keeps the heavy truck traffic out of the historic district of Thomas.
While I think a lot of the truck drivers that venture out onto U.S. 219 today between Parsons and Thomas are familiar with the route and its dangers, I am confident that most of them would be happy to be on a new ADHS corridor highway instead.
