Traffic was slow for several hours on Interstate 91 after a tractor-trailer carrying folding tables and chairs rolled over in Meriden.
The truck was heading north and flipped over in the median between exits 15 and 16 around 7:30 a.m.
No one in the truck was hurt, but the fuel tank was damaged and crews from the state Department of Transportation and the state Department of Energy and Environmental Protection responded.
It’s not clear what caused the vehicle to go off the road.
State police said they hope to repoen the left lane between 12:30 p.m. and 1 p.m.
