Troop M's Nathan Branosky said the truck flipped on the ramp from Route 33 southbound to Interstate 78 eastbound in Lower Saucon. Drivers on Route 33 south are being detoured onto I-78's westbound lanes, state police said.
The ramp was still closed while first responders worked the scene around noon, Branosky said.
