Emergency crews are investigating a serious crash involving a motorcycle and a box truck on Route 128/I-95 in Weston Thursday.

Massachusettes State Police confirmed troopers were responding to the crash, which is at the off-ramp to the Mass. Pike. The ramp was closed after the crash, as was the I-90 westbound off-ramp to I-95, but they have since reopened.

State police said the same curve was the site of a tractor-trailer crash last week.

More details were not immediately available. The scene is active.
