The Road Core All Existing feature class represents currently existing roads that are within or in close proximity to U.S. Forest Service administrative unites (i.e. National Forests). Each feature represents a segment of road where the attributes are the same. Attributes apply either to the entire road or to some measured distance along the road. Only NFSR roads have been edge-matched. Some public roads may be duplicated, especially near boundaries of adjacent National Forests. Non Forest Service roads are entered at the discretion of each National Forest.
