ReportWhat the New England 511 feed carried over the holiday weekend.
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.
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.
In October 2026, MileCheck's archive of the New England 511 feed held 48 unique reports, including 47 work-zone reports. The routes with the most reports were I-93, I-95 and I-89. Counts reflect what the feed publishes, so a state whose DOT posts only closures shows only closures. Read the October Highway Report.
The map above shows full closures from the New England 511 feed as red markers, 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. The page checks MileCheck's feed 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.
