Overlap Wythe County Motorists should expect congestion due to high traffic volumes. In Henry County, about 2.5 miles of Route 58 between Spencer and the Patrick County line are being widened to four lanes. The bridges over the Mayo River also are being widened. In Patrick County, three miles of Route 58 between Nettleridge and Route 697 is being widened. The speed limit in both these work zones is reduced to 45 mph.
Traffic is shifted onto two temporary detours.
The speed limit is reduced to 40 mph throughout the project. Motorists need to watch for changing traffic patterns. A new interchange is being built in Blacksburg where the new Route 460 Bypass, Route 460 Business and the Smart Road connect. Traffic delays will occur at times at the Route 460 Blacksburg Bypass and Route 460 Business intersection. A new interchange will be built and the bypass relocated.
