This document discusses Clinch Mountain, a ridge located in Tennessee and Virginia that separates the Clinch River basin from the Holston River basin. It notes that when Highway 25E was realigned through Bean Station, Tennessee in the 1980s, it was necessary to cut a new, lower gap through Clinch Mountain. It also mentions that Interstate 26 was lowered at Sams Gap on the Tennessee-North Carolina border, representing the only two instances where a highway gap in the region was lowered for a new roadway. The document concludes by thanking the reader for their time.
