Icy conditions caused dozens of accidents, involving hundreds of cars, across the Hudson Valley this morning.

Westchester County police say they dealt with numerous separate accidents spread across the all the major parkways. They say one person was killed this morning about 6:30 a.m. in a crash on the ramp connecting the eastbound Cross County Parkway to the northbound Bronx River Parkway. That ramp will remain closed for several hours as a result of the ongoing accident investigation.

Also, video sent in by a News 12 viewer showed a chain-reaction crash involving at least 35 cars side on the northbound Hutchinson River Parkway, just one exit after the Cross County Parkway. A nearby homeowner tells News 12 that she saw cars sliding down the road sideways because of icy conditions.

State police say there were multiple accidents on I-87, I-287, I-684, and I-95 throughout Westchester County due to the weather. Many of the accidents blocked multiple lanes on those roadways. At one point, they say there were five different accidents on the Thruway between Yonkers and Ardsley.
