Police are investigating a fatal motorcycle accident in the Lincoln Tunnel that snarled the morning rush in and out of New York City.

Port Authority police say a 23-year-old woman passenger died and the 35-year-old man who was driving the bike was injured in the crash around 3 a.m. Wednesday in the New Jersey-bound north tube.

The north tube reopened around 6:30 a.m. following the investigation.

However, motorists faced delays because only the south tube was open for traffic headed into New York City and the center tube was open for motorists headed to New Jersey during the investigation.

New Jersey Transit trains and NY Waterway ferries cross-honored all bus tickets because bus passengers faced delays when the north tube was closed.
