Much of the Blue Ridge Parkway in North Carolina and Virginia has been closed to motorists because of heavy accumulations of snow and ice as well as downed trees.
The National Park Service announced Wednesday that many sections of the roadway are blocked by gates, but also said that some portions of the road cannot be blocked to traffic and are hazardous.
Three counties in North Carolina and five in Virginia have sections that are not blocked and are either dangerous or impassable and should be avoided.
The park service says it could take weeks to clear the road, especially at higher elevations because colder temperatures limit melting of ice and snow.
Drivers who use closed sections of the parkway are subject to either fines, citations or both.
