Labor Day 2026 in New Hampshire

What the New England 511 feed carried over the holiday weekend.

Driving across New Hampshire

I-93 is the state's spine, up from the Massachusetts line through Manchester and Concord, then north into the White Mountains and Franconia Notch to the Vermont line, about 131 miles. I-95 crosses the 18-mile seacoast past Portsmouth between Massachusetts and Maine. I-89 cuts northwest from Concord toward Lebanon and the Vermont line. US-3 shadows I-93 and keeps going north where the interstate ends, and US-302 threads Crawford Notch.

What the season does to New Hampshire's highways

North of Concord the road climbs and the weather changes fast. Snow squalls, black ice and high wind hit I-93 and US-302 through the notches while the seacoast stays dry. Around mile marker 105, I-93 narrows to a two-lane parkway through Franconia Notch, with little shoulder and no easy way around a blockage. NHDOT posts closures by route and milepost on New England 511.

Before a New Hampshire road trip

  1. Check the map above for anything red on your route, then open New England 511 for the DOT's own detour and restriction text.
  2. Look at the road. The New Hampshire cameras show the pavement itself, and most carry the mile marker.
  3. For the long haul, the I-95 corridor page carries alerts for every state the route crosses, not only New Hampshire.
  4. Know how to say where you are. Dispatch, 911 and tow companies ask for the route, the direction and the mile marker. How to report your location on the highway.
  5. Carry the app. The mile marker works offline in all 50 states, and the same New England 511 alerts show on your route as you drive.

What September looked like

Over 25 daily snapshots from September 1 to 25, 2026, MileCheck's archive of the New England 511 feed held 74 unique reports, including 3 crash reports and 66 work-zone reports. The routes with the most reports were I-93, I-95 and NH-12. Counts reflect what the feed publishes, so a state whose DOT posts only closures shows only closures. Read the September Highway Report.

Questions, answered

Is the highway closed in New Hampshire right now?

The map above shows every full closure New England 511 is publishing as a red marker, crashes in orange, and weather and hazard alerts in blue and purple. Closures the DOT has posted for a future date are listed as scheduled, and ramp and lane closures sit under the toggle so the list stays readable. It reloads every five minutes. If the feed cannot be reached the page says so instead of showing an empty map. For the official list, open New England 511.

Where do I check New Hampshire road conditions?

New England 511 is the official source, and dialing 511 in most states reaches the same information by phone. This page reads the same New England 511 feed and adds the New Hampshire cameras, the corridor and pass pages, and your own mile marker if you carry the app.

How often does this page update?

Every five minutes. MileCheck's server fetches the New England 511 feed, converts it to one format shared by all 50 states, and caches it for five minutes. Each alert also carries the time the DOT last updated it, shown in the list.

Does the MileCheck app show these alerts?

Yes. The app shows the same New England 511 alerts on your route, ahead of your position, with the mile marker you are passing. The mile marker works offline in all 50 states. Live alerts are part of MileCheck Premium, $49.99 a year or $9.99 a month after a 7-day free trial.
