A loaded cement truck rolled over on Interstate 495 north in Andover, Massachusetts on Friday afternoon, blocking several lanes of traffic.
State police are on scene and said the truck was blocking the middle and right lanes. The accident was reported around 1 p.m.
The truck has since been removed and travel lanes have reopened. The breakdown lane remains closed as of 5 p.m. for repairs.
Aerial footage from NBC10 Boston's Sky Ranger helicopter showed the vehicle on its side just off the highway. A section of guardrail was destroyed in the crash.
Motorists are urged to seek alternate routes if possible. Traffic delays should be expected.
