It's about 270 miles from Asheville to Roanoke on the BRP. That would be approximately 6+ hrs drive time at 45 mph compared to traveling on I81 and arriving in Roanoke in about 3.5 hrs. The BRP in NC is not as convenient to I81 as it is in VA, so you will save more time using I81 in NC and enjoying the BRP in VA.
