Several photos posted to Twitter by people stuck in traffic showed a lengthy backup. One woman said on Twitter that she had been parked on the highway for more than 30 minutes, and that most cars had their engines off with people standing outside their vehicles on the side of I-90.
Drivers were encouraged to seek an alternate route.
The crash happened shortly after 8 p.m. Friday, and both agencies said serious injuries have been reported.
Westborough Fire said multiple units responded to the scene after they received calls saying two people had been injured, including one who was unconscious.
No other details were immediately available, including how many vehicles were involved. NBC10 Boston has reached out to state police for more information.
