A tractor-trailer overturned and spilled a load of lumber onto I-287 at the entrance ramp for the New Jersey Turnpike on Friday morning.

The crash happened around 10:30 a.m. right at the entry plaza for Exit 10, impacting drivers trying to get onto the turnpike. The southbound lanes of I-287 were backed up for more than a mile. 

Chopper 2 flew over the scene, where large pieces of lumber were strewn about the roadway. A pile of wood could also be seen on a grassy median. 

At one point, vehicles were able to pass by on the side, but it was slow going. By noon, all southbound lanes were closed for the cleanup. 

Investigators have not said what caused the tractor-trailer to roll over, and there's no word of any injuries.
