The northbound side of Route 8 in Torrington was closed on Thursday after Connecticut State Police said a dump truck lost its load of wastewater sludge.
State police said 32-year-old Carlos Campoverde-Arcentales of Norwalk was driving a tri-axle commercial dump truck in the right lane when sludge shifted in the back of the truck and came out through its rear gate.
The sludge came into contact with another vehicle and all of the lanes of the highway.
The other vehicle sustained minor damage to its side from the sludge.
Route 8 was closed near exit 44 around 12:15 p.m.
There were no reported injuries.
Department of Transportation, Department of Energy and Environmental Protection and state police assisted with the investigation.
DEEP said the sludge came from a Waterbury water treatment facility.
The dump truck was temporarily put out of service for not having its rear door properly secured.
Campoverde-Arcentales was able to properly secure the remaining sludge, which allowed officials to put the vehicle back into service.
DOT crews had the task of cleaning up the sludge.
Campoverde-Arcentales was given an infraction for "failure to secure load" and for operating an unregistered commercial vehicle on a public highway.
