Blue Ridge Tunnel was the longest of 4 tunnels built on the Blue Ridge Railroad to cross the Blue Ridge Mountain range at Rockfish Gap near Afton Mountain in Central Virginia.
The Blue Ridge Railroad was owned by the Commonwealth of Virginia. Its purpose was to provide a crossing of the Blue Ridge Mountains for the Virginia Central Railroad. The Virginia Board of Public Works, always keen to help with "internal improvements" owned a portion of Virginia Central stock, and that railroad had found a planned crossing at Swift Run Gap to be financially unfeasible around 1855.
To protect its investment, and enable transportation, the State then incorporated and financed the Blue Ridge Railroad to accomplish the hard and expensive task of crossing the Blue Ridge mountain barrier to the west. Rather than attempting the more formidable Swift Run Gap, under the leadership of the great early civil engineer Claudius Crozet, the state-owned Blue Ridge Railroad built over the mountains at the next gap to the south, Rockfish Gap near Afton Mountain, using four tunnels, including the 4,263-foot Blue Ridge Tunnel at the top of the pass, then one of the longest tunnels in the world. It was completed in 1860.
The Blue Ridge Railroad became part of Collis P. Huntington's Chesapeake and Ohio Railway after the American Civil War, and helped complete Virginia's longterm dream of linking its navigable rivers of the Chesapeake Bay watershed with the Ohio River. The Blue Ridge Railroad is now part of CSX Transportation. It is operated under lease by the Buckingham Branch Railroad .
