Issue SUP-Construction for US 340 Rockslide Repair Project

Harpers Ferry National Historical Park » Issue SUP-Construction for US 340 Rockslide Repair Project » Document List

The West Virginia Department of Transportation, Division of Highways (WVDOH), in cooperation with the Federal Highway Administration (FHW A), and the National Park Service (NPS) prepared an environmental assessment (EA) to evaluate the impacts to repair and remediate a rockslide area along US 340 within Harpers Ferry National Historical Park (Park) in Jefferson County, West Virginia and Loudoun County, Virginia. US 340 is a high-volume (approximately 24,500 vehicles per day), two-lane principal arterial roadway that traverses the water gap through the Blue Ridge Mountains created by the Shenandoah and Potomac Rivers, between Harpers Ferry, West Virginia, and the West Virginia/Virginia state line. The natural rock slopes adjacent to US 340 range in height from 150 feet to 600 feet above the US 340 roadway grade. These slopes exhibit varying degrees of rockfall activity and present concerns to the traveling public. Ongoing maintenance activities by the WVDOH are required to maintain the road for safe travel by the public through this area.
