The 66-vehicle pileup, including 55 trucks and 11 passenger vehicles, over a mile span on the westbound side of the highway happened around 3 p.m. Wednesday in Clinton County, State Police said Thursday.
The stretch remained closed Thursday afternoon with contractors trying to clear the vehicles, according to cops.
A second passenger died during the incident due to a medical issue, but it was not connected to the crash, cops said.
The fatality was one of five lives claimed during Winter Storm Gail, the first snowstorm of the season — which dumped more snow on New York City than all of last year combined.
Another death was reported just outside Pittsburgh when a man was hit by a plow around 4:45 p.m. while walking with a snowblower, according to the local CBS station.
