Ritchie County has 9500 people living there. The other in-between county on D, Doddridge, has 8,400. There is no shortage of good housing in either Clarksburg or Parkersburg. Spending millions, and, BTW, finishing the road decades before vastly more important projects, (which is WV tradition, the state having built its interstates and corridors in roughly reverse order of importance) so a few hundred people can play weekend farmer is really a waste, when you contrast it is Corridors that have really worked, because they are built where there are people, and where there is topography that is there for development.
I know the history of Corridors H and E reasonably well, and know enough to be dangerous about some of the others.
Regarding the purpose and need of the ADHS, consider the following:
1. The "D" stands for development. I am O.K. with that.
2. A senior manager and career MDOT/SHA staff person (now retired from state service) said that from his point of view (keeping in mind that Maryland has only three counties in the ARC footprint - Garrett, Allegany (that's the correct spelling) and Washington),
the main idea behind the ADHS was to induce traffic (this was a session at an annual meeting of the Transportation Research Board - a notorious anti-highway activist who was in the audience had a fit and looked like he was ready to have a stroke after hearing that).
It appears to me that U.S. 19 (Corridor L) has induced traffic and economic activity.
As an aside about Corridor L, I have heard that the Summersville police engage in predatory speed limit enforcement, but I saw nothing happening when I was through there recently. On the other hand, it appeared that the police from Oak Hill were engaged in revenue raising on their part of U.S. 19 near Beckley. I have also seen local law enforcement doing revenue collection on Corridor D.
3. Again in Maryland, ADHS was used to get I-68 (Corridor E) built, and provide a good road connection between the two westernmost of those counties and the rest of the state. The old route - U.S. 40 - was in places a wretchedly bad and dangerous highway - I-68 was (and is) a big improvement and has reduced the isolation of Garrett and Allegany. Combined with I-79 and more recently WV-43/PA-43, it has also improved road access from the Pittsburgh area.
4. It is not just in West Virginia where the difficult parts are left for last. On Corridor E, the most difficult parts in Maryland were Sideling Hill and the section between Cumberland and Flintstone. They were the last parts to get built and opened to traffic. In West Virginia, it seems that Corridor H between Parsons and Davis is going to be the most-challenging to design, engineer and build. Is the other remaining West Virginia part, between Wardensville and the W.Va./Va. border as difficult?
I am not sure about the difficulty of building Corridor H in Virginia, since VDOT has done almost nothing about the 14 miles between the state line and I-81 near Strasburg.
5. I agree with Presidents John F. Kennedy and Lyndon Baines Johnson about the need to make improvements in the Appalachian part of the United States - using federal dollars because of the multi-state nature of Appalachia and the problems there. If anything, that need is more-pressing now, given the long-term decline of coal mining and related jobs in many Appalachian counties. Some of the ADHS corridors improve access to state and federal parks and recreation. One other benefit that is IMO more important - they provide network redundancy in a part of the nation where there is not enough of it. Corridor H, when completed, as well as Corridor E are good examples of this, as they provide east-west links across the mountains between the I-64 and I-70 corridors.
