The eastbound lanes of the Thruway are back open Wednesday morning between the Westfield and Dunkirk-Fredonia exits.

State Police say one person died in a multi-vehicle crash just after 7 p.m. Tuesday.

Eastbound traffic was diverted off the Thruway at exit 61 while crews worked to clear the scene.

All lanes reopened around 2 a.m. Wednesday.

Troopers are still looking into what caused the crash.
