GRAFTON (CBS) — A tractor-trailer rollover on the Mass Pike westbound in Grafton late Wednesday morning backed up traffic as crews worked to free the driver. Both sides of the highway were shut down temporarily so a medical helicopter could land.

Traffic was at a standstill heading west as the truck blocked all three lanes. The truck driver, a 60-year-old Brockton woman, was eventually freed and taken away on a stretcher.

Her injuries are not life-threatening, the Westboro Department said.

Drivers were urged to seek an alternate route and warned to expect delays. The crash was cleared by 12:46 p.m. Staff
