Drivers commuting into New York City Thursday morning should avoid the George Washington Bridge.

Heavy traffic remains after all of the bridge’s upper-level lanes to New York were closed due to police activity during the rush hour commute, according to the Port Authority of New York and New Jersey.

FDNY received a call about a motorcyclist who had been struck by a tractor-trailer on the bridge’s upper level around 5 a.m. First responders arrived and found the motorcyclist dead at the scene. The victim has not been identified.

As of 8:15 a.m., lanes were beginning to reopen on the upper level, according to the Port Authority.

Elsewhere, the Port Authority is also reporting delays in the Holland Tunnel and on the Outerbridge Crossing and Goethals Bridge as of 7 a.m. because of congestion.
