US 340 ROCKSLIDE REPAIR PROJECT

The West Virginia Department of Transportation, Division of Highways (WVDOH), in cooperation with the Federal Highway Administration (FHWA), 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.

The NPS prepared this FONSI because a portion of the protective structures is to be located outside the WVDOH right-of-way and on NPS property, a Special Use Permit (SUP-Construction) is required from the NPS to authorize short-term access and construction on NPS property, while a Highway Easement Deed (HED), granted through a Title 23 federal land transfer, will be necessary to authorize long-term operation and maintenance of the facility.
