The closure began shortly after 10 a.m. Saturday morning, following a crash on I-91 North between Exits 5 and 6 in Rockingham and Westminster. Shortly after, I-91 South was closed as crews landed a helicopter on the interstate in support of the crash response.

Connecticut State Police say a tractor-trailer crashed on the Route 20 exit ramp to I-91 north in Windsor Locks on Monday afternoon, closing a lane.
