New Hampshire’s historical highway markers illustrate the depth and complexity of the state's history and the people who made it, from Abenaki Native Americans to poets, painters and contemporary sports figures; from meeting houses to stone arch bridges and long-lost villages; and from factories and cemeteries to places where international history was made.

The New Hampshire Historical Highway Marker Program is jointly managed by the N.H. Division of Historical Resources and N.H. Department of Transportation (NHDOT).
