The Department of Energy and Environmental Protection (DEEP) said a flatbed tow truck went off the road and through a guardrail. This caused diesel to spill into and alongside the road.
Crews drained the remaining fuel in the truck's tank, cleaned the road and removed about 40 yard of soil, according to DEEP.
Connecticut State Police and Glastonbury firefighters also responded to the scene.
No additional information was immediately available.
