Radical plans to introduce 20mph speed limits across the city centre and on four in five city streets have been approved by councillors.
Members on the Transport and Environment Committee voted by 11 to three in favour of the plans, with city transport convener councillor Lesley Hinds making the case for the measure in order to improve safety.
A Conservative Party amendment against the plans was defeated, and a detailed implementation plan will now be brought before the committee in March, ahead of the start of a phased roll-out starting later this year.
Tory transport spokeswoman councillor Joanna Mowat had complained that the plans were uncosted, and that investment should be made in improving road surfaces. Her party colleagues also argued for a scaled-back 20mph plan that did not include major roads in the city centre.
Council officials at the committee meeting confirmed that it could take “several financial years” to fully roll-out the plans.
