For its entire length, Clinch Mountain has only one true gap through which the ridge is completely sliced in half and continues as Clinch Mountain on either side, divided by Big Moccasin Creek. It is named Moccasin Gap and runs between Weber City and Gate City, Virginia. The Norfolk Southern Railway and U.S. Highways 23-58-421 utilize that gap because there is no elevation in the division of the mountain. Moccasin Gap is currently planned to undergo major mountain removal to accommodate a planned highway project. The natural appearance of the gap will be altered significantly. 30 miles northeast of Moccasin Gap, in Russell County, U.S. Highway 58 Alternate crosses Clinch Mountain at Brumley Mountain, between Hansonville and Abingdon.
