One lane has re-opened on the northbound carriageway of Chapel Field Road in Norwich following this morning's work on a burst water main.

The emergency repairs caused major delays for traffic in the city centre this morning.

The northbound carriageway had been completely closed between St Stephens roundabout and the B1108 Convent Road because of a burst water main.

Anglia Water first closed the road at 7pm yesterday with repairs due to be completed by 7am today.

But they could not be completed in time and a new team was been brought in to carry on with the work.

An Anglian Water spokesman said one lane of the road had now re-opened but a full road closure would be needed again tonight from 9pm until 7am tomorrow.

Big queues delayed drivers trying to head towards the Grapes Hill part of the city with traffic stretching along the A140 Ipswich Road and on the A11 Newmarket Road.

The burst water main also affected the water supply to some houses in the Norwich area this morning. Anglia Water said the mains was switched off earlier today to ensure homes had enough water pressure. It was switched back on at about 10am.

Some households were concerned after noticing a smell of chlorine once the supply was restored but Anglian Water spokesman insisted the water was safe to drink.

She said engineers carried out a host of safety tests before switching the water back on and would not have done so if it did not meet the strict standards.

A sterilisation process carried out before the water was switched back on would have left a smell but would eventually fade.
