Gas works on a Norwich road have been described as 'nothing out of the ordinary' by the National Grid following concerns from residents.

Gas engineers have been at Silver Road since last Thursday after reports of a gas leak.

One resident, who does not want to be named, said the first thing he knew about it was when engineers knocked on his door.

'They came to the door at about midnight and asked me to move my car,' he said. 'Then about seven vans turned up as well as a digger and they have been on the road ever since.

'No smoking signs were put up and there was a really strong smell of gas. They are now digging up the road and it causing a number of travel problems for residents.'

The National Grid's website states that work is expected to last until February 9.

Across the city there are a number of ongoing engineering works following gas escapes. Winchcomb Road, Foster Road and Linton Crescent are just some of the other streets where work is happening.

A spokesperson for the National Grid said: 'Our engineers are dealing with routine reports of gas escapes, these are nothing out of the ordinary and the workload is what we would expect for this time of year.'
