The Virginia Department of Transportation will begin installing new signals at three intersections on alternate Route 58 in the Pennington Gap next month. New signals will also be installed on Route 23 in the Applachia area of Wise County and the Gate City area of Scott County.
Traffic engineers for VDOT determine if a signal is needed by evaluating multiple factors including:
The number of vehicles and pedestrians that use the intersection
The physical makeup of the intersection
Traffic delays during peak hours
Average vehicle speeds
The number and types of accidents that have occurred there
