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.)
Appalachia Appalachia ( ) is a cultural region in the Eastern United States that stretches from the Southern Tier of New York to northern Alabama, Mississippi and Georgia. While the Appalachian Mountains stretch from Belle Isle (Newfoundland and Labrador) in Canada to Cheaha Mountain in Alabama, the cultural region of Appalachia typically refers only to the central and southern portions of the range. As of the 2010 United States Census, the region was home to approximately 25 million people.
