2 multi-car crashes inside the Prudential Tunnel under investigation

Two separate multi-car crashes in the Prudential Tunnel — that caused significant delays on the Mass. Pike eastbound — are under investigation, according to state police.

Police report the first crash occurred at 3:40 p.m. near the Prudential Tunnel entrance on I-90. Four vehicles were involved including a Toyota Rav4, Hyundai Elantra, Jeep Wrangler, and Mercedes Metro Van.

The Jeep became fully engulfed in flames after its driver tried to flee the scene following the initial crash. The driver of the Jeep — identified as a 29-year-old man from Boston — is now facing charges.

The Jeep and Hyundai needed to be towed. No injuries were reported.

At around 3:50 p.m. a six-vehicle crash occurred at the mile mark 133 on I-90 in the tunnel. The vehicles include a Subaru SUV, Honda Odyssey, Honda CRV, Ford Econoline, Toyota Rav4, and Chevy Malibu.

Two people were transported from this crash to nearby hospitals with minor injuries. All vehicles except the Subaru needed to be towed.

Both right and left lanes were closed following the crash but reopened shortly after. Delays continued on the Mass. Pike afterward.
