The westbound lanes reopened before Thursday's morning rush hour.
Police say a tractor-trailer smashed into several vehicles about 70 miles east of New York City on Wednesday. The crash set off a series of accidents that left at least two dozen vehicles strewn across several hundred yards of the eastbound lanes.
The tractor-trailer was carrying debris from Superstorm Sandy. At least three vehicles caught fire.
A 68-year-old woman from Blue Point, N.Y., died at the scene. A car involved in the initial collision with the tractor-trailer was incinerated beyond recognition.
