Questions

What is the lowest bridge in New Hampshire?

7′ 1″ on Sawyers Crossing Road, by its posted height.

How many low clearance bridges are in New Hampshire?

121 posted bridges and tunnels under 14′ 6″, and 90 under 13′ 6″, the usual height of a semi-trailer.

Posted heights from OpenStreetMap contributors (ODbL), as Orbit keeps them, rounded down to the inch. Heights change with resurfacing, snow and ice: always go by the sign on the bridge. Missing a bridge or a wrong height? Tell us.

Tall vehicle?Set your truck or RV height in Orbit and it routes you around every bridge you won't fit under, and warns you before one on the road ahead.
