Lengthy Delays Reported on I-495 in Westborough Due to Crash

WESTBOROUGH, MA — A crash on I-495 northbound just before Route 9 led to extended delays Wednesday morning.

According to the Westborough Fire Department, first responders arrived at the scene shortly after 7 a.m. No injuries were reported; however, traffic has been reduced to one lane.

The Massachusetts Department of Transportation (MassDOT) confirmed that lane closures will impact the I-495/I-90 interchange, causing significant slowdowns during the morning commute.

As of 9:40 a.m., officials reported an 8-mile backup on I-90 eastbound prior to I-495, exacerbating congestion due to the incident.

A photo from the fire department shows a tractor-trailer with its front wheels over the middle barrier.

Authorities have not yet determined the cause of the crash. Emergency crews remain on-site for traffic management and cleanup.
