The N.C. Department of Transportation produces and maintains a variety of maps and data – from travel maps for the public to technical designs for transportation planners – that play a part in the planning, funding, construction and maintenance of roads and highways in North Carolina.
Most of these resources are
available on Connect NCDOT, the department's resource site for business, professional and working partners.
