Three people have been taken to hospital and a man has been arrested following a serious crash on the A47.

Two vehicles collided on the outskirts of Norwich in Postwick at about 12.10pm on Thursday.

A white Ford Transit van was travelling in the wrong direction on the westbound carriageway at the time of the collision.

The van overturned and the driver has since been arrested.

Fire crews from Acle, Great Yarmouth, Carrow and Earlham attended and released people from the vehicles.

The A47 was closed in both directions until 12.55pm when the eastbound carriageway reopened.

The westbound carriageway remained closed until 4.04pm.

There was heavy congestion following the crash and police warned people to avoid the area.

Dave Peters was driving on the opposite lane of the A47 when he saw the van.

He said: “I saw this cloud of dust and it wasn’t until I got closer that I could see it driving in the fast lane in and out of traffic.

"I couldn’t believe it, he was going very fast."
