State Mapping Resources

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 website for business and community partners as well as the public.

These traffic volume maps – also known as annual average daily traffic volume maps – and reports are published annually.
