How long is the extension of the blue ridge mountain range that Nichol's Gap Road was built over?
Nichol's Gap Road The Nichol's Gap Road was a central Pennsylvania highway established in the 18th century near Maryland extending westward from the Black's Gap Road "just west of Little Conewago Creek" at the "Crofs Keys" stand of James Black. The road was past both the Rock Creek Church and 1761 Samuel Gettys tavern where Gettysburg would be surveyed in 1786. The highway was built over the South Mountain (Maryland and Pennsylvania) via Nichol's Gap ( ) and down the Devils Racecourse into the Cumberland Valley, allowing access to the 1762 Hagerstown, Maryland. Called the "Hagerstown Road" during the Battle of Gettysburg, parts of the road are now designated (east-to-west): U. S. Route 30 in Pennsylvania, Pennsylvania Route 116 (Fairfield Road to Fairfield, Pennsylvania), Iron Springs Road, Gum Springs Road, and Old Route 16 (the summit section through Nichol's Gap--"Fairfield Gap" during the American Civil War—no longer has a roadway.)
North Carolina Highway 89 North Carolina Highway 89 (NC 89) is a 61 mi east–west state highway route that mainly runs through small communities and towns in northern North Carolina including Mount Airy and Danbury. The entire route spans only two counties in the state: Surry and Stokes. It can be accessed from the Blue Ridge Parkway via Virginia's State Route 89 (the highway that continues from NC 89's western terminus) or an interchange with NC 18 which intersects NC 89 near its western terminus. Interstates 77 and 74 both intersect NC 89 west of Mount Airy.
