New Hampshire Department of Transportation – Concord, NH

Connecting New Hampshire Safely and Efficiently

The New Hampshire Department of Transportation (NHDOT) is the executive agency responsible for the planning, construction, and maintenance of the state’s transportation infrastructure. Headquartered in the John O. Morton Building on Hazen Drive in Concord, the department oversees a vast network of highways, bridges, airports, and public transit systems . Its mission is to provide a safe and efficient transportation system that supports the state’s economic growth and quality of life. The Concord campus serves as the central command for statewide operations, housing key administrative bureaus and engineering divisions.

Divisions and Services

NHDOT is organized into several major divisions. The Division of Operations includes the Bureau of Highway Maintenance, which manages snow removal, pavement repair, and drainage across thousands of lane-miles. The Division of Aeronautics, Rail, and Transit oversees aviation safety, supports local airports, and coordinates public transportation and freight rail services . The Bureau of Turnpikes manages the state’s toll road system, including E-ZPass operations, although specific transponder services are largely handled online or at dedicated walk-in centers. The headquarters also houses the Bureau of Construction, which supervises active road and bridge projects.

Public Interaction and Permitting

For the general public and businesses, the Hazen Drive office is a resource for various permits, such as oversize/overweight load permits, driveway permits for access to state highways, and parade permits. The department also provides real-time travel information through its New England 511 service. Visitors to the headquarters should note that while the DMV is located nearby on the same campus, NHDOT focuses on infrastructure rather than driver licensing . Security screening is required for entry into the building, and visitor parking is available in designated lots.
