The council is calling for 20mph speed limits on a network of “red routes” across Wandsworth.

The council has already introduced a 20mph limit on all the roads it manages which includes its busiest A-roads.

However, on the borough’s main trunk roads - which are all controlled by transport organisation TfL - speeds of up to 40mph are permitted.

According to the council lower speed zones boost road safety and improve local air quality.

Transport spokesman, Cllr John Locker, has written to London Mayor Sadiq Kahn to urge him to support the town hall’s efforts.

The Mayor organises TfL and if approval is granted 20mph speed limits could be introduced on the A3, A24, A205, A214, A306, A3205 and A3220.

West Hill, Battersea Rise, Latchmere Road, Trinity Road, East Hill, Swandon Way, Battersea Park Road, the Upper Richmond Road, Balham High Road, the Upper Tooting Road, Tooting High Street and all of the Wandsworth one-way system would see changes.

Cllr Locker said:

"We support 20mph limits because we believe they deliver a range of key benefits. Lower speeds mean safer streets and can encourage other forms of sustainable transport like cycling and walking. It also means quieter streets which are a welcome boost for people’s quality of life.

“Now we need the Mayor to step up to the plate and introduce the scheme on TfL’s red route network. These are London’s busiest roads and suffer the worst impacts of air pollution. Reducing the speed limit on these strategic roads in Wandsworth would provide huge relief to our residents, especially those who live on these main roads.

“We sincerely hope the Mayor heeds this important message and takes the action we are calling for.”
