Crews responded to Route 20 in Brimfield after a dump truck rolled over onto a Toyota Corolla Monday afternoon.
State police were notified just after 1 p.m. that the truck had toppled over on top of another vehicle along the road, leaving the westbound lanes closed.
One individual involved in the crash sustained minor injuries and has since been transported to Harrington hospital.
Police told CBS 3 they expect the road to be re-opened no later than 5 p.m.
The incident remains under investigation.
