Actually... for those who are interested there is a way that involves the bypass around Winchester, hitting 50 earlier, going through Wardensville and via Corridor H.
Regardless of how you bypass Winchester, maybe it's coming in on Rt. 7, you hit 81 North until the next exit off at Rt. 11 / Rt. 37 and make a left at the stop light. Stay stray through the next 3 stoplights and then it's 4 lane cruising on Rt 37 the partial bypass of Winchester. You have two options, with the first being more out of the way than necessary.
You can get off at the first exit from Rt37 onto 522 North and stay on that road until Gainesboro. There is a 6 mi cut-off road between 522 and Rt 50 at Gainesboro, but is only 45mph.
Rather though, stay on Rt 37 past the Winchester Hospital Exit upto the Rt50 exit and make a right and go through 4 or 5 stoplights past the 'new' walmart. From that point onward you will be driving about 14mi to Gore VA. You have the option of staying on 50 with it being a single lane road up the allegheny front, or you can make a left onto Rt 259 at Gore. From there it's a 19mi drive to Wardensville to get onto Corridor H and ... off you go!
I have a dentist in Leesburg and this is the way that *IS* the quickest from Wardensville to get there and back with best traveling and least hassle. So I know the Rt7 / Greenway pretty well by now and if anyone is looking to come that route. Here's an accurate link to get to CV from Leesburg via this route: Leesburg to Canaan Valley Drive
