More than 300 city centre roads will have a 20mph limit by the end of the year, Sheffield Council has confirmed.
The authority revealed this week that it was pushing ahead with plans announced in the summer after a positive response to a consultation.
As a result the speed limit will drop to 20mph on most city centre roads, bar a few major thoroughfares such as Arundel Gate and Derek Dooley Way.
The aim is to improve safety and therefore encourage more people to walk and cycle around the city centre.
Thirty-three people responded to a consultation, with 19 in favour of the 20mph limits. Seven were opposed and seven did not express a view either way.
The council says there has been an increase in traffic accidents over the past few months.
Cabinet member for transport and sustainability Jack Scott said: “Anyone who’s been in our city centre recently will have seen that it is growing rapidly and for the better, with cranes, new shops and new developments.
"It needs to be a place where safety and sustainable travel are actively supported and encouraged.
“I’m pleased that the consultation was received so positively. This Labour council is absolutely determined to improve road safety throughout the city and 20mph zones play a big role in this."
The zones will be marked with signs, but the council says it does not have money for traffic calming measures such as humps.
Coun Scott said the lower limit would also improve air quality.
“I am aware of concerns, not least from reading the Star letter pages, that travelling at 20mph could negatively affect air quality," he added.
"However, the evidence actually shows that at a constant lower speed a driver will use less fuel, and safer roads should mean more people taking up walking and cycling instead.
"I am absolutely committed to improving safety on our roads and taking real action to improve Sheffield’s air quality. Pleasingly, this measure should help in both of these respects in city ward”.
The 20mph restriction has already been introduced in Darnall, Gleadless Valley, Heeley and Stannington, while schemes are being considered in Firth Park and Woodhouse
Coun Moya O’Rourke was elected in the city ward in 2015 and has spoken to residents about the issue regularly.
“Since my election I made a promise to the ward that I would make our city centre roads safer and more environmentally friendly – and I have been pushing for 20 mph zones in the centre to do just that," she said.
“I’m delighted that so many residents in my ward contributed to the council’s public consultation."
The council is also considering measures to tackle congestion on the inner ring road.
The Sheffield Green Party group said they had included funding for a 20mph scheme in their budget since 2014.
Coun Rob Murphy, who also represents the city ward, said: “A city centre 20mph speed limit zone will greatly improve the safety of city centre residents, who currently face the worst road traffic accident rates in Sheffield.
"We of course understand it is necessary for some people to use cars in the city centre but this limit is needed to protect pedestrians and cyclists."
