Work has started again on a problematic Norwich city centre road scheme - more than 12 months after the junction was initially closed.

Traffic management barriers are now in place in Colegate, at the junction with St Georges Street, and will remain in place until Tuesday, April 18.

The area was initially shut for nine weeks in March last year for work as part of the multi-million pound Transport for Norwich project.

The work included putting in a raised table, kerb realignment and footway widening. But some of the paving slabs which were put down cracked.

Two thirds of the work to replace them took place in November, but contractors Tarmac always said they would have to return this year to complete the work.

The work started this morning, with work taking place between 8am and 5pm each weekday, up until Thursday, April 14.

The traffic management barriers will be left in place to protect the works over the Easter Weekend. No work will be carried during this period and all barriers are due to be removed on Tuesday. April 18.

A spokeswoman for Tarmac said: 'Access will be maintained for small delivery vehicles, cars, pedestrians and cyclists for the duration of the works and local businesses and organisations will remain open as usual.

'Teams on site will be available to provide advice and guidance to access as work progresses.

'Every effort will be made to minimise the impact on local businesses, residents and organisations at the same time as maintaining a safe environment for both members of the public and the workforce.'

The Transport for Norwich programme aims to encourage the use of more sustainable forms of transport, such as public transport, cycling and walking, while improving the capacity of the road network.

But the project has suffered from difficulties. Tarmac had to return to resurface two sections of the £5.7m Push The Pedalways project – in Tombland and The Avenues.

And, while probing what went wrong, Tarmac discovered a wider problem with material traced to its Ipswich plant. That meant Hall Road in Norwich had to be shut again last summer for resurfacing - a year after the road was initially resurfaced.
