Two tractor-trailers were involved in a crash that caused one of them to roll over Wednesday night on the Massachusetts Turnpike in Grafton.
Police say the crash happened on the eastbound side of Interstate 90 at mile marker 98.2.
The crash caused serious injuries, the Massachusetts Department of Transportation said shortly before 10 p.m.
The number of people hurt was not immediately known.
The crash led to significant closures. As of 9:20 a.m. MassDOT said the two left lanes were getting by, but the right lane remained closed for cleanup.
