Six motorcycles crashed on I-495 near exit 3 in Middleborough just after 3:30 p.m. today, according to State Police.
All six bikers, who were traveling together, suffered injuries and were transported, two by helicopter, to hospitals, said State Police Lieutenant David Wilson. Their conditions were unknown.
The crash caused a back-up that stretched 9 miles to Route 44 in Middleborough, according to Gina Tempesta, a traffic reporter with SmartTraveler.com.
Wilson said all three lanes of traffic had reopened by 5 p.m. Troopers are on the scene, investigating the cause of the crash.
