摘要：	This Environmental Assessment (EA) addresses the proposal by the National Park Service (NPS) to rehabilitate the pavement and drainage on Newfound Gap Road within the study area and to construct left-turn lanes at seven intersections along the same corridor. The project is located in the Great Smoky Mountains National Park, Swain County, North Carolina. The location of this proposed project is Newfound Gap Road, a north-south roadway within the Great Smoky Mountains National Park that stretches from the Oconaluftee Visitor Center in Cherokee, North Carolina to the Sugarlands Visitor Center near Gatlinburg, Tennessee. The study area extends from 500 feet north of the Collins Creek Picnic Area to the southern boundary of the Park. Portions of the pavement on Newfound Gap Road are badly deteriorated and require rehabilitation to provide a safe driving surface. Some drainage facilities also are in very poor condition. Existing traffic volumes on Newfound Gap Road approach or exceed roadway capacity during peak visitor seasons. Some intersections within the proposed project limits have poor roadway geometry that results in less than adequate sight distances for approaching motorists. A high number of accidents, including one fatal accident and several with injuries, have been documented at some of these intersections. The frequency and type of accidents, combined with the high traffic volumes, indicate a need for improvements at these intersections to increase public safety and improve traffic operations. The Parks goal in selecting a preferred build alternative is to provide a safe, long-lasting driving surface for visitors and Park staff. Although safety is a primary concern, significant effort has been given to preserving the Parks natural and cultural resources by minimizing impacts to the environment by the proposed improvement.
