Map Highways (MapHighways)
The Map Highways (MapHighways File Geodatabase Feature Class) line layer represents highways in North America. The Map Highways line layer is created by selecting Functional Class (FuncClass) codes (1,2,3) and Render Class (RENDER_CL) codes (1,2,3,7) from the Streets feature class. Map Highways is intended as a visual mapping layer with no other Streets attributes considered.
