MINA, N.Y.—A 15-miles stretch of the eastbound lanes of Interstate 86 in New York's southwestern corner have reopened after a chain-reaction crash caused by icy conditions claims the life of a motorist.

The Chautauqua County Sheriff's Office says the driver of an eastbound tractor-trailer stopped in the highway's driving lane around 3 a.m. Thursday because another rig had jackknifed in front of him in the town of Mina, on the Pennsylvania border 70 miles southwest of Buffalo.

Deputies say the driver of a box truck was killed when he drove into the rear of the stopped tractor-trailer. The driver's name hasn't been released.

The westbound lanes between Exit 4 in Mina and Exit 7 in Sherman reopened about two hours after the crash, while the eastbound side reopened around 8 a.m.
