Police have arrested a man following a crash on the A19 this morning which saw five-mile tailbacks.
It happened on a section of the road between the A689 and the A1027 at Billingham at about 5.30am and involved an Audi A8 and a white Vauxhall Corsa.
The road was closed in both directions for a period of time but the southbound carriageway was later opened.
The whole section of road is now clear.
Cleveland Police said they have now arrested an 18-year-old man on suspicion of burglary and a number of driving offences.
