Here's you new route from DC

I did this in 3 hours to Bethesda....With the new stretch of Corridor H open from Moorefield to Foreman, a new set of directions is needed for those who want to spend less time driving. It involves using 66 West so departing during rush hour is not advisable.

From home go to 66 West, then go South on I-81 at the end of 66. In three miles, take the second exit and turn right at the stop sign on HWY 55 West. The speed limit on 66 once you get past Haymarket and also on 81 is now 70 MPH. It just got changed.(70 minutes)

Drive 20 miles on 55 West to the sign for new HWY 55 and take new HWY 55. (25 minutes)

Go 35 miles on the new HWY to the end at Patterson Creek Road (Route 5). Turn right to go north one mile. (35 minutes)

Turn left on Greenland Gap Road and drive 6 miles to T intersection or similar ending where you turn or bear left on Scherr Road and go another 1/2 mile to HWY 93 at the road with 30 curves. (10 minutes)

Go to Davis and on, as usual. (45 minutes)

Total 185 minutes equals 3 hours 5 minutes.
