WESTON (CBS) – A tractor-trailer crashed on a ramp from the Massachusetts Turnpike to I-95 (Route 128) in Weston early Wednesday, shutting it down for nearly three hours at the start of the morning commute.

The truck rolled over on the ramp from the Pike eastbound as it was heading to 95 north just after 5 a.m. State Police shut down the ramp and diverted ramp traffic onto 95 south. The ramp from 95 north to the Pike was also blocked off.

State Police said the driver, a 50-year-old man from Springfield, had minor injuries. He was issued a citation.

There’s no word yet on what caused the crash. No other vehicles were involved.

The truck was towed away and the ramp re-opened around 8 a.m.

No other information is available at this point in the investigation.
