The A19 has reopened to traffic after a crash involving a car and a parked lorry caused delays.
The incident happened on the southbound carriageway near the junction with A690, leading to a diesel spillage.
Traffic building up behind the collision was turned around back down the A19 as efforts continue to clear the scene.
A spokeswoman for Northumbria Police said: "Police received a report at about 11.04am today that a Vauxhall Astra had veered off road and collided with a lorry parked in a lay by on the A19."
Police later confirmed the road had been reopened.
"The road is now reopened and traffic is moving freely again after a collision on the A19 just north of the A690 turn off. Thank you to everyone for their patience whilst emergency services worked to clear the road," the force said in a tweet.
Officers said no one was seriously injured in the incident.
