A single-vehicle rollover briefly closed left lane traffic on I-91 North near the 39.4 mile marker on Friday morning at approximately 8:45 a.m. The Deerfield and Greenfield fire departments, state police and South County EMS arrived to see a 2011 Honda Pilot on its side in the median area. Both the female operator and a male passenger refused treatment at the scene and traffic lanes were reopened around 9:30 a.m. STAFF PHOTO/CHRIS LARABEE
