Study Purpose US 29 / 15 Lee Highway & Route 215 Vint Hill Road DRAFT Evaluation & Recommendations This study will develop and evaluate alternative conceptual designs for the US Route 29 (Lee Highway) and VA Route 215 (Vint Hill Road) intersection in Fauquier County. The existing intersection has a high number of accidents and some intersection sight distance issues have been noted during field observations by VDOT staff. There is a project in development that would relocate Vint Hill Road to the west, which includes a grade separated interchange that will address the issues at this intersection in the long term. However, the interchange project is several years from construction and completion. Therefore, VDOT would like to explore other alternatives that could address the intersection issues sooner. Identified Concerns • The US 29 northbound approach has a high number of rear-end accidents. • US 29 northbound traffic has very limited sight distance over the hillcrest approaching Vint Hill Road. • Right turn roadway and vehicles from Vint Hill Road are not apparent to US 29 northbound traffic (Vint Hill Road traffic and roadway are obscured by hill between left-turning and rightturning traffic) • Striping on US 29 approaches does not meet intersection standards (no solid lane line between lanes and no lane arrows) • Left turns from US 29 northbound are not prohibited but there is no left-turn lane. (Uturns are prohibited – traffic counts show a couple of U-turns.) • US 29 has very high through volumes in both directions. • US 29 southbound to Vint Hill left turn traffic has very limited sight distance of oncoming traffic (if signal fails, lefts would be quite difficult) US 29 Vint Hill Rd • The roadway lighting at the intersection is not functioning properly. Each light turns off and on at seemingly random times. • Warning signs on the US 29 northbound approach are obstructed by trees and can only be seen for a short distance. • On US 29 northbound approaching Vint Hill Road the static sign mounted to the mast arm at the hillcrest is not very visible at night. • The left-turn / through lane from Vint Hill Road to US 29 southbound is only about 10 feet wide.
