SEE: Multi-Car Crash Brings Chaos To Snowy GWB

WASHINGTON HEIGHTS, NY — A multi-car pileup on the George Washington Bridge forced several lane closures and left smashed up cars strewn about the span's upper level, according to officials and witness video.

The crash occurred around 2:45 and forced the Port Authority of New York and New Jersey to close all New York-bound lanes on the bridge's upper level. Delays are expected to continue on the bridge as lanes reopen.

Shortly before 6 p.m., the Port Authority announced that the crash site had been cleared and that drivers should expect residual delays of greater than 60 minutes on the bridge.

One motorist on the bridge captured the aftermath of the crash and posted a video to social media. Drivers can be seen standing on the bridge assessing damage to their vehicles and several tractor-trailers were involved in the collision. At one point, the video-taker said "oh my god" as he passed by a Lexus that appeared to have been struck by a big rig.

The crashes did not result in any major injuries, a Port Authority spokeswoman said. The Port Authority and Port Authority police are operating on the scene to clear the bridge and to lay down sand and salt to combat ice.

Effects of the crash could be felt by drivers throughout Washington Heights, as a backup of cars waiting to get onto the bridge stretch down Broadway. The outbound entrance to the brdige was shut down during attempts to clear the bridge of wreckage, according to the 34th NYPD Precinct.

Drivers should avoid the George Washington Bridge if possible, a Port Authority spokeswoman said. Recommended alternatives between New Jersey and New York City are the Holland and Lincoln Tunnels.

"Are you ok? I was almost like you. I could stop it's so slippery in here," the motorist said. "Oh my god. GW cluserf***"
