An overturned tractor-trailer caused a traffic backup on Interstate-80 eastbound near Parsippany and Montville Township Tuesday night.
The truck overturned near Exit 48 and Hook Mountain Road just after 8 p.m. New Jersey State Police say another vehicle was also involved in the accident.
The trailer was carrying a load of bricks which apparently spilled all over the roadway, along with fuel.
State police say it will take several hours to clean up the accident. The eastbound lanes were closed for a time, and traffic was being diverted around the accident.
Police say no serious injuries were reported.
