Ipswich town centre is to get a blanket 20mph speed limit to help beat congestion and make the streets safer for pedestrians.
The new restrictions will come into force on 1 December and will cover the business and shopping areas of the town.
Ipswich Borough Council, which will apply the limits on 48 town centre streets, has said the scheme is not an anti-car measure, but a way of ensuring the roads are safer and more welcoming.
Councillor Harold Mangar, who has responsibility for transport, said: "The streets around the centre of Ipswich are not built for the volume of traffic it has to take.
"We have decided that we should reduce the speed limit to make the heart of the town centre as welcoming as possible."
A council spokesman added Ipswich was not becoming an anti-car town and its car parking prices reflects this.
