ROCHELLE PARK, New Jersey (PIX11) – Traffic in New Jersey is finally back to normal on route 17 tonight after a tractor trailer carrying McDonald’s supplies flipped on the roadway early Thursday.

It’s unclear what caused the packed vehicle to flip just after 1 a.m.  The tractor trailer, which was loaded with Happy Meals and breakfast sandwiches, slammed into the corner of a building and tore down several power lines near West Passaic Street.

The accident closed part of the southbound highway for six hours in Rochelle Park.

Incredibly, no one was seriously injured in the accident.
