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.
In October 2026, MileCheck's archive of the Mass511 feed held 284 unique reports, including 17 closure reports, 48 crash reports, 202 work-zone reports and 1 weather report. The routes with the most reports were I-95, I-90 and US-1. 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 Mass511 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 Mass511.
