Scores more areas of Norwich are set to have 20mph limits, after councillors today agreed that should be the default restriction for residential roads.

Some parts of the city, such as Heartsease, bits of the city centre and Earlham have already had limits and zones put in place.

But council officers want to go further and make all residential C and U class roads 20mph.

Dozens more roads in Old Catton, Mile Cross, Sprowston, Tuckswood, Eaton, Cringleford, Tuckswood and parts of Lakenham, would follow by Easter next year.

Magdalen Road and a number of residential streets nearby are also earmarked to become 20mph zones this summer.

The council is using money from the government's multi-million pound Cycle Ambition grant to bring in the zones around where cycleways are being improved.

There is £600,000 left in that pot, which must be used by the end of next year.

Officers acknowledge future roll-outs would depend on other sources of funding once that money is used up.

The council is also looking to use more 20mph roundels on roads.

Bert Bremner, Labour city and county councillor for University Ward, said: 'The reality is we have had a really positive approach to 20mph.

'The benefits have been spilling out. The changes in areas are just really positive.'

But he warned: 'When the blue and yellow pedalway work is finished, it's very unlikely there will be any more money. Norfolk County Council has very little and it all depends on what we get from the government.'
