Before you dig, build a driveway, or run utilities inside a state highway right of way, the New Hampshire Department of Transportation can require a bond guaranteeing you restore the highway when you finish. NHDOT sets the amount on your permit — and we issue it at a flat 3% with no credit check.
















No underwriting queue for the standard right-of-way bond — enter your amount, pay, and file with NHDOT. Here is the whole thing:
Your business details, the bond amount the permit requires, a short description of the work and location, and the effective date — that is the entire application.
No credit check and no waiting — the executed bond is generated as soon as you pay. Larger amounts may get a quick review.
Submit the executed bond with your right-of-way or excavation permit application. Wet-ink originals mailed whenever the district office insists.
Bond amount × 3% = your premium, one-time, $275 minimum. Enter the figure NHDOT set on your permit and the premium updates.
New Hampshire's highway law (RSA 236) makes it unlawful to excavate, build a driveway or access, or run utilities inside a state highway right of way without a written permit from the Commissioner of Transportation. The permit governs how you cut and restore the road — and the permitting authority may require a bond to back that restoration.
The bond is a highway-restoration guarantee running to the State. If you leave the pavement, shoulder, ditch, or embankment unrestored — or restored improperly — NHDOT can recover against the bond to put the highway right. RSA 236 lets the authority decide the form of security; a surety bond is the common choice over cash or a letter of credit.
Because the figure tracks the restoration cost of your particular job, the amount is whatever your permit names — there is no single statutory number. Enter that figure and we issue the bond at a flat 3% with no credit check. (Many local roads fall under city or town control, not NHDOT — this page is the state highway permit.)
Submit the application with the bond amount your NHDOT permit set — the executed bond is generated instantly, ready to file.
