National Highway System (NHS)

These maps have been prepared by the Louisiana Department of Transportation and Development, Office of Multimodal Planning in cooperation with the U.S. Department of Transportation Federal Highway Administration. They were created from a GIS environment in the Transverse Mercator Projection, North America Datum 1983 UTM Zone 15N coordinate system. Each map is available as an image in the Adobe Acrobat Reader .pdf format. Although these maps were designed for large format plotters, by using Adobe Acrobat Reader version 6.0 or later, they may be printed to any desired size.
