A tractor-trailer rolled onto its side in a three-vehicle crash on Interstate 495 northbound at Exit 14 in Middleborough, Massachusetts, on Saturday morning, November 7, and one person was taken to a local hospital with serious but non-life-threatening injuries, according to the Massachusetts State Police. The crash, at about 8:24 a.m., involved the tractor-trailer and two passenger vehicles, Sgt. Gregory Jones of the State Police media relations office said. Hours later, the highway was still not fully open: the truck was off the road by 1 p.m., but a northbound lane stayed closed for cleanup and, by mid-afternoon, traffic was getting by only in the breakdown lane.

State Police closed Exit 12 and, for a time, one lane of traffic was getting by at the scene, Jones said. The tractor-trailer had been removed from the highway by 1 p.m., while the northbound lane remained closed for cleanup. By 3:16 p.m., traffic was getting by in the breakdown lane on the northbound side of I-495, according to State Police. The Massachusetts Department of Transportation's Mass511 traveller listing for the crash — on the stretch between Exit 15 at Route 44 and Exit 14 at Route 18 in Middleborough — was still active at 5:10 p.m., and it listed no detour and no expected delay figure.

A correction that shows why the direction matters
The first report of this crash, based on the Mass511 listing, placed it on I-495 southbound between Exit 15 and Exit 14. State Police corrected the record on Saturday evening: the crash was on I-495 northbound at Exit 14. Awaaz Punjab is publishing the corrected direction and location, because for drivers and dispatchers planning around a closure, northbound and southbound are two different problems — and because the correction itself is part of the verified record of this crash.
State Police have not announced when Exit 12 and the closed northbound lane will fully reopen. If you are heading north on I-495 toward Middleborough, check Mass511 for current conditions before you travel, and expect the breakdown-lane pattern to slow traffic near Exit 14.
What State Police have not said
State Police have not said what caused the crash, which vehicle the injured person was in, or when Exit 12 and the closed northbound lane will reopen. No names have been released, and no charges or citations have been announced. The injured person was described only as having serious but non-life-threatening injuries and as having been taken to a local hospital, which was not named in the statement. Awaaz Punjab will update this story when police release the cause or a reopening time, and will not fill those gaps with speculation.
What is documented is the sequence, and it is a long one for a Saturday: a morning rollover at 8:24 a.m., an exit closure at Exit 12, a heavy removal operation that cleared the truck itself by 1 p.m., a cleanup closure that kept a travel lane shut into the afternoon, single-file traffic in the breakdown lane by 3:16 p.m., and an active state traveller listing still running at 5:10 p.m. with no detour posted. For anyone who was stuck in it, that timeline — not a single moment — is the story of the day on this stretch of I-495.
Why an I-495 rollover ripples beyond Middleborough
Interstate 495 is the outer highway belt around the Boston metropolitan area and one of eastern Massachusetts' main working corridors, carrying commuter traffic and a heavy flow of trucks between the Route 44 and Route 18 corridors through Plymouth County. A rolled tractor-trailer is never just a local delay on a road like this: freight that cannot get through on schedule pushes onto smaller state routes, and dispatchers — including the many Punjabi and South Asian truckers who run New England lanes — have to re-time deliveries around a closure whose end time, in this case, police still had not given by Saturday evening.
Saturday's crash also landed on a corridor with a serious history at this same town: State Police have investigated fatal multi-vehicle crashes involving tractor-trailers on I-495 in Middleborough before, which is one reason a rollover here draws a full response — troopers, removal crews and a cleanup operation measured in hours rather than minutes, even when, as on Saturday, the injuries are reported as non-life-threatening.
What happens next: the State Police investigation into the cause continues, and the practical questions are the reopening of Exit 12 and the closed northbound lane, and whether any citation follows. Drivers should treat Mass511 as the live source tonight — it was still listing the incident at 5:10 p.m. — and Awaaz Punjab will update this report when the listing clears or police issue a further statement.
