BREAKING: Truck Overturns At Lincoln Tunnel [VIDEO]

A truck has overturned at the Lincoln Tunnel, causing a major backup at the helix leading up to the connection to Manhattan, Hoboken official said.

Injuries were unknown at press time.

The Port Authority said only buses departing from the agency are allowed to use the outbound tunnel and they're being diverted onto local streets after crossing the Hudson River.

Other traffic leaving Manhattan to head to New Jersey must use the Holland Tunnel or George Washington Bridge, according to Hoboken officials.

Video shows the truck leaning against a concrete barrier, with delays up to an hour.

NJ Transit is cross-honoring bus tickets on trains, ferries and light rail to provide other travel options.

A heavy-duty wrecker arrived just before 6:30 a.m. to clear the truck from the road.
