ROSELAND — A tractor-trailer carrying 7,000 gallons of raw sewage flipped over along a highway entrance ramp in Essex County this afternoon, authorities said.



The vehicle was traveling at an "unsafe speed" when the driver lost control and crashed on a ramp connecting the northbound Eisenhower Parkway to Route 280 East in Roseland at 1 p.m., according to Trooper Christopher Kay, a State Police spokesman.



The driver, 26-year-old Michael Maloney of Haskell, was treated for minor injuries at the scene and issued a summons for careless driving, Kay said.



Members of the Roseland Fire Department and Nutley Hazardous Materials team were called to the scene because of a leak in the trailer after the crash, Kay said, although it is unclear how much waste may have escaped the vehicle.



The wreck shut down the entrance ramp for nearly six hours, according to Kay, but no other injuries were reported.
