20250918 15421600 1.0 TRUE NetworkBase_Modified An arc layer for visual representation of state-maintained road centerlines segmented by a subset of road characteristics necessary for routing. To this system, all structures in the current Structures Management Unit's database that cross or carry a state-maintained road have been added.This dataset was created for the express purpose of routing overweight/oversize vehicles along state-maintained roads within the PIMS application supplied by NCDOT's Engineering Applications Development group. No usage outside this application should be attempted. Certain aspects of the original line & structures data layers were modified for usage within the PIMS application and non-PIMS usage can result in incorrect routes.
