Police have renewed their appeal for witnesses to a fatal crash on the A47 Southern Bypass on Sunday.
At around 12.15pm a red Peugeot 206 was travelling westbound when it left the carriageway and went down an embankment near the Thickthorn Roundabout flyover.
The male driver died at the scene and a female passenger was treated for minor leg injuries but has since left hospital.
Police are still not able to release the identification of the man who died in the crash.
Officers want to speak to anyone who witnessed the collision, particularly the driver of a black Ford Mondeo seen nearby at the time.
Calls should be made to Norfolk Police's Serious Collision Investigation Team on 0845 456 4567.
