An enormous pile-up car crash on Interstate 95 northbound involved nearly 55 vehicles, police say.

The crash occurred around 6 a.m. before Exit 39 in Wakefield. The large-scale collision involved approximately 55 cars, according to Massachusetts State Police. Nearly 30 of those vehicles were towed away.

Lieutenant Tom Ryan reported the collision caused minor injuries, but it is unclear at this time how many were hurt or the extent of their injuries. Ryan said they expect everyone to be OK.

Several miles of I-95 NB were closed, and could not be accessed from I-93 in both directions, according to MassDOT. Traffic was backed up for several miles to Woburn during peak commute hours as officials redirected traffic onto I-93.

Gov. Baker declared a two-hour delay for non-essential state employees following reports of several multi-car crashes across the state:

We will update this story as more information becomes available.

UPDATE: Just before 9 a.m., Mass. State Police reported the accident had been cleared and that traffic was beginning to move again.
