Signs have started to appear on almost 200 streets which will complete the rollout of 20mph speed limits to residential road across Lytham and St Annes.
The streets to the north and west of St Annes town centre are involved in phase four of the £9.2m countywide scheme introduced by highways authority Lancashire County Council as a key road safety measure.
Rural Fylde was among the first local areas to see controversial lower limit signs go up and the rest of Fylde has followed over the past two years.
The order for the latest streets involved came into effect last Monday.
Vali Birang, the county council’s head of sustainable transport and safety, said: “We’re now completing the final phase of the programme to introduce 20mph speed limits in residential areas.
“Where communities have concerns about speeding we’re continuing to work with police and local people to monitor speeds, influence drivers’ attitudes, and enforce the limit.
“The community road watch and school watch activities have been well supported by police, schools and local people and we’ll continue these activities to support the 20mph schemes.
“Interim results of an independent assessment into the early phases of the programme show overall casualties have reduced by nearly 30 per cent in the areas studied, which is very promising.”
