Emergency services were at the scene of a serious crash on St Nicholas Road in Great Yarmouth.
The crash took place at around noon on the junction with Nelson Road North and involved a Mercedes sprinter van and a Toyota.
At least one person was cut free from their vehicle.
They treated a man in his 60s who had suffered a serious chest injury and head and facial injuries.
He was taken to James Paget University Hospital for further treatment though his injuries are not believed to be life threatening.
Five police cars, two fire engines and an ambulance were all on scene.
Highways were also called to the scene due to fuel spillage.
Brian Taylor, 33, from Cobholm, was near the incident when it happened.
He said: 'It was an almighty shunt, I didn't see it but I just heard a huge bang.
'I turned around and saw the Toyota in the wall severely damaged, the van wasn't as bad but still very damaged.'
St Nicholas Road was closed off to motorists but has been reopened while part of Nelson Road North was also blocked off after the junction.
