A fuel spill closed part of Interstate 91 south in Meriden on Monday morning.
State police said an oil truck leaked fuel from a tank between exits 18 and 17 and the right and center lanes were closed.
Investigators said the drive shaft on a truck broke and punctured the cargo tank, which released approximately 500 gallons of waste oil.
The Meriden Fire Department built a dike to minimize impact to a catch basin, police said.
The oil also impacted the roadway, the soil at the edge of the road and a catch basin network, authorities added.
The state Department of Transportation applied sand to help contain the oil and an environmental contractor was at the scene with a vacuum truck and cleanup equipment, police said.
The puddled oil and sand will be collected, the catch basin network will be cleaned, a minor amount of soil at the edge of the roadway will be removed and the remainder of the waste oil in the cargo tank will be emptied, according to investigators.
