A 15-year-old boy has been taken to hospital by air ambulance with a broken leg after being knocked down in Hartlepool.
Police were called to the A689 at its junction with Brenda Road, close to the close to the Stag and Monkey pub, just after 5pm.
The driver is not believed to have been hurt.
Delays were aggravated by a three-vehicle accident which closed a lane of the southbound A19 slip road with the A689 at Wolviston services about quarter of an hour later.
No-one was hurt.
