A motorcyclist has been left with serious injuries following a collision on the A140 which left the road closed for several hours.
Police were called to the road at Stoke Ash, south of Eye, at about 6.45am on Tuesday.
The AA traffic map suggested there were queues forming in both directions while the road is cleared, with vehicles tailing back for two miles.
A police spokesman confirmed the road had been sealed off after a Kawasaki motorcycle and a Ford Transit van collided.
The motorcyclist was taken to Norfolk & Norwich University Hospital for treatment for his injuries, which are believed to be potentially life-changing.
Recovery was called and the vehicles were moved off the main carriageway to nearby Wood Hall Lane at 8.47am.
The road had reopened by 11am, a police spokesman confirmed.
