Bicycle Highway-Access Laws in New Hampshire

The rule
Bicycles are prohibited on Interstate highways in New Hampshire. Bicycles are prohibited on New Hampshire Interstate highways (I-89, I-93, I-95) and on the toll-road portions of the Everett, Spaulding, and Central Turnpikes under New Hampshire Department of Transportation (NHDOT) controlled-access regulations. Conventional US and state routes (US-3, US-4, NH-101) remain open to bicycles.
What this means in practice
Stick to surface streets, US routes, state highways, and dedicated paths. If your route in New Hampshire appears to use an Interstate, plan a detour before you start.
Bigger roads, longer rides
Size a road bike for shoulders, group rides, and rural highways
Highway-access and group-riding rules favour riders who can hold a straight line at speed. Start with a frame that fits.
