UPDATE: This article has been updated with additional information from a State Police statement. Additional updates have added information on two other serious crashes in Westborough.
WESTBOROUGH – The Mass Pike onramp to I-495 north re-opened on Monday afternoon after several hours of delays following a tractor trailer rollover there shortly before 11 a.m.
Crews in Westborough remained busy, however, with a series of other major traffic accidents in town.
Located near the Westborough/Hopkinton town line, the tractor trailer incident clogged traffic, with backups visible along I-495 north and I-90 as of 10:45 a.m.
“Expect significant delays,” the Westborough Fire Department warned in a statement on social media.
Westborough crews were on scene alongside Hopkinton Fire personnel.
A photo shared from the crash site showed a truck resting on its side as traffic inched by.
Information on the condition of the truck driver was unavailable as of press time.
State Police were then on scene as of 12 p.m., though, with plans to temporarily close the ramp later in the afternoon, once the crashed truck was righted.
Police detailed these plans in a statement on social media, explaining that the full closure would last roughly 30 minutes.
“We will update,” State Police said.
The ramp did indeed re-open around 2 p.m., according to State Police, following the successful removal of the crashed truck.
Separate crashes take place around Route 9
As first responders cleared the scene on the Mass Pike ramp, crews in Westborough continued their response to what has been a dangerous day on local roads.
One incident at the intersection of Route 9 and Otis Street took place just before 12 p.m, with photos showing at least one car with heavy damage to its passenger side.
Emergency crews then responded to the intersection of Route 30 and Route 9 around 2 p.m. following a head-on collision with injuries there.
Route 30 was closed around that crash.
Crashes follow previous incidents
The tractor trailer crash was the latest in a series of incidents around the MassPike/I-495 interchange, coming just over a month after another crash involving large trucks in the area.
Taking place on April 8, that incident took hours to clear, prompting backups for miles along the MassPike and I-495.
The state has approved a roughly $466 million project to redesign the interchange, presenting data in 2019 that documented 460 accidents in the area between 2011 and 2015.
There were two fatal crashes during that time.
Work is expected to wrap on that redesign process at some point in either 2026 or 2027, with officials promising a comprehensive safety overhaul of the area.
The crashes around Route 9 separately come less than a week after another serious incident at the intersection of Route 9 and Lyman Street last week.
A motorcycle and an SUV collided there last Wednesday, leaving the motorcyclist with serious but non-life threatening injuries according to Westborough Police.
A tractor trailer then ran into hanging traffic signals on Route 9 at Otis Street on Saturday, prompting more traffic delays while crews worked to make repairs.
