There is a large hill (up and down) between Christiansburg’s main buisness district and the interstate exits off of the 460 bypass. Police tend to frequent the area between dusk and midnight to catch employees of Dish Network leaving work. The trap is clear by 12:30 am. Speed limits are posted at 55 MPH but you can generaly get by between 60-65. The road is safe to at least 100 mph as it’s a straight shot.
