 30 miles northeast of Moccasin Gap, in Russell County, U.S. Highway 58 Alternate crosses Clinch Mountain at Brumley Mountain, between Hansonville and Abingdon.All other transportation crossings, as noted below, require an elevation climb to the top of the Clinch Mountain.When U.S. Highway 25E was realigned into a four-lane highway northwest of Bean Station, Tennessee in the 1980s, it was necessary to cut a new gap into the top of Clinch Mountain, which lowered the original gap elevation by 200 feet.
