An accident at the Lincoln Tunnel caused major delays in both directions for the morning commute Thursday in New York City. 

The crash on the outbound side of the Helix shut down several lanes for roughly six hours overnight and into the early morning.

The investigation had all outbound lanes closed onto 495. Drivers were being detoured off to the Weehawken-Hoboken local exit. 

Only one inbound lane was open, causing delays that stretched back to the New Jersey Turnpike and onto Route 3. 

All lanes reopened shortly after 7:30 a.m., but residual delays remain around the area. 

Drivers should take the George Washington Bridge or Holland Tunnel for alternate routes.
