Every closure and crash Mass511 is publishing, on one map with the route and mile marker. Below it: the live cameras, the I-90 and I-95 corridor pages, and what the season does to Massachusetts's highways. For the whole country, see the US closures map.

ReportWhat the Mass511 feed carried over the holiday weekend.
I-90, the MassPike, is the east-west spine, the New York line, the Berkshires, Springfield, Worcester, Boston. I-95 arcs around Boston as the beltway's outer ring and runs the coast toward Rhode Island and New Hampshire. I-495 is the outer orbit through the commuter belt, and I-93 runs north to south through downtown Boston. US-6 carries the Cape traffic, and Route 2 runs the Mohawk Trail across the north of the state.
Nor'easters hit the whole state at once, and I-90 through the Berkshires gets real snow when Boston gets rain. MassDOT posts speed restrictions and travel bans on Mass511, and the Pike's reduced-speed orders come by mile range. Since the 2020 renumbering, the Pike's exit numbers match its mileposts. Summer Fridays on Route 3 and US-6 toward the Sagamore Bridge are a traffic story more than a weather one.
Over 25 daily snapshots from September 1 to 25, 2026, MileCheck's archive of the Mass511 feed held 67 unique reports, including 2 closure reports, 18 crash reports and 39 work-zone reports. The routes with the most reports were I-93, I-95 and I-90. Counts reflect what the feed publishes, so a state whose DOT posts only closures shows only closures. Read the September Highway Report.
The map above shows every full closure Mass511 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 Mass511.
Mass511 is the official source, and dialing 511 in most states reaches the same information by phone. This page reads the same Mass511 feed and adds the Massachusetts cameras, the corridor and pass pages, and your own mile marker if you carry the app.
