A van driver whose vehicle was drawn into a sinkhole as it collapsed said he was 'shaken in his seat'.
Units from Norfolk Police closed Angel Road in Norwich on Thursday morning at around 9am after the hole opened up between Eade Road and Rosebery Road, close to Angel Road Junior School.
Pupils from the school had to leave around 2pm and the road was closed after highways officers from Norwich City Council and Anglian Water staff investigated the issue.
It remains closed and a diversion has been put in place via Constitution Hill and Woodcock Road.
Michael Reynolds was driving a Tuffnells delivery van down the road when one of the rear wheels caught a pothole, which collapsed and took the van with it.
Mr Reynolds said: "When the road collapsed it shook me in my seat.
"I tried to get the van out, but I was told to leave the van where it is because the Tarmac was moving. So I switched it off, took the keys out the ignition and got the hell out of there.
He added: "It is in a dangerous situation. There is a possibility it [the van] could roll on its side."
The lorry was moved from the road at around noon, according to a resident.
First said its 21 and 22 bus services were being diverted via Constitution Hill and Woodcock Road in both directions due to the road closure.
A spokeswoman for the Angel Road schools said safety had not been impacted by the sinkhole and that the schools would send out messages to parents and carers about collection arrangements "in due course".
Indy Singh, owner of Chish and Fips on Angel Road, said the sinkhole was a nightmare as the road closure sign was beyond his fish and chips business.
He said he had served very few customers tonight on what was normally a busy evening.
Ben Stocker, who believed the sinkhole was six inches deep, said: "I hope it is a water pipe issue and not a chalk mine. This is normally a very busy road but it is nice and quiet now. I can get a parking space now."
Mr Stocker, who lives next to the sinkhole, added the sinkhole appeared next to a speed bump on the 20mph road and before the hole appeared.
He said he heard lots of bangs from cars this morning going over the speed bump.
Mr Stocker believed it was lucky a van got stuck in the hole and not a car.
