Kenneth Squire, 78, a member of Acle Indoor Bowls Club, was in his Smart car travelling westbound between the Harford and Thickthorn junctions when the accident happened.
The van was overtaking him when Mr Squire's car collided with its side, before veering off the carriageway and into small bushes and trees.
He was taken to Addenbrooke's Hospital, where he died the following day.
An inquest into his death, held this month at Norfolk Coroner's Court, heard Mr Squire, a former lorry driver and care home boss, had been suffering from a cold at the time, but had felt well enough to play bowls.
The crash happened at around 8.55pm on March 6.
