One person is dead after a tractor trailer went off southbound I-95 and down an embankment in Groton Tuesday morning.

WFSB-TV is reporting that fire officials told them one person is dead.

The accident occurred near exit 89 and has tied up traffic.

State police are on the scene.

Police are warning drivers to slow down because of slippery conditions and water pooling as a result of heavy rain and leaves on roadways.

And with snow and sleet coming Thursday afternoon, drivers should consider filling up their windshield washer reservoirs with a winter mix.
