A pedestrian died at the weekend after he was in collision with a lorry at Elm on the A1101.
The man in his 20s suffered serious head injuries and later died in the Queen Elizabeth Hospital, King’s Lynn.
The accident happened just after 8pm on Sunday.
Norfolk police closed the road, which links Wisbech to Downham Market, for two hours while officers started the investigation.
Officers are now appealing for witnesses to the crash to contact the Serious Collision Investigation Team on the 101 number.
Elm parish council chairman John Brand has been calling for improvements to be made on roads elsewhere in the parish after a series of accidents.
Cllr Brand wants traffic calming measures to be installed on the corner on the outskirts of nearby Friday Bridge on the B1101.
He said: “People come off that corner every week.
“I am concerned about all the crashes in Elm but talking to Cambridgeshire County Council is like talking to a brick wall.”
Chris Crofts, who represents Emneth on West Norfolk Council, is calling for pedestrians and cyclists to wear bright clothing while using the A1101. He said: “On occasion I have come across pedestrians in the dark and they have not been wearing bright clothing. I would advise pedestrians and cyclists to wear bright clothing.”
