virginia tech smart road, virginia smart road project
The Virginia Smart Road, also known as simply the Smart Road or Smart Highway, is a short, limited access road in Montgomery County, Virginia, used for the testing of pavement technologies and as a proving ground for new transportation technologies The Smart Road is currently a 22-mile 35 km stretch of road with turn-around loops at either end Eventually, the road will be extended to a total of 57 miles 92 km, which will directly connect US Route 460 in Blacksburg to Interstate 81 with an interchange near mile marker 121; however, there is no set time frame for completion The Wilson Creek Bridge was built for the Smart Road and, at 175 feet 53 m tall, is the second tallest bridge in Virginia The road and bridge are operated and maintained by the Virginia Department of Transportation It is also part of the Proposed Interstate 73 Corridor
