Bridge Maintenance

Welcome to the Bureau of Bridge Maintenance!

Bridge Maintenance is responsible for the maintenance and repair of all NHDOT owned highway bridges.

In New Hampshire, a structure is considered a bridge if it has span length of ten feet or greater.
Currently there are 2,162 (2022) bridges owned and maintained by the State of New Hampshire.

The Bureau performs maintenance, preservation, rehabilitation work and provides emergency response to support the safe and reliable movement of people and goods over bridges in New Hampshire. In addition, we operate and maintain the states movable, lift span brides. The Bureau operates from a central office in Concord that coordinates the activities of our construction crews statewide.

How does Bridge Maintenance respond to bridge graffiti?

Department Policy Regarding Graffiti.

This Bureau will review complaints about graffiti on state-maintained bridges. If the words or drawings are deemed particularly offensive, profane, or slanderous we will schedule a crew to cover it up. Graffiti that police departments report as gang related will also be scheduled to be covered. We do not have dedicated crews of people to review and cover/remove all the graffiti that is present. If we were to, it would be at the expense of the safety and infrastructure preservation work we prioritize.
