TfL and Lambeth Council construction on A23 Streatham Hill

Work will start in the coming weeks to transform travel along the A23 Streatham Hill, with improvements for walking, cycling, and public transport users.

Transport for London (TfL), in partnership with Lambeth Council, will deliver new pedestrian crossings, a protected cycle route, upgraded pavements, and improved bus lanes.

Will Norman, London’s walking and cycling commissioner, said: "I'm delighted TfL is working in close partnership with Lambeth Council to transform travel in Streatham Hill, to deliver new pedestrian crossings, a protected cycling route and improved bus lanes.

"The start of construction work follows an overwhelmingly positive response to TfL's consultation on their plans, with so many respondents saying the new improvements to pedestrian crossings, pavements, bus lanes and a protected cycling route will make them feel safer on bike and on foot.

"The new scheme will better connect communities to transport hubs, schools, green space and each other, building a better London for everyone."

The works will begin on Monday, August 4 and are expected to continue until autumn.

There will be lane restrictions in both directions on the A23 between Holmewood Road on Brixton Hill and Sternhold Avenue on Streatham Hill.

The first phase of the work will involve removing the central reservation.

To install traffic management safely, the A23 will be closed overnight between A205 Christchurch Road and B221 Sternhold Avenue from 10pm to 5am on Sunday, August 3 and Monday, August 4.

TfL said further overnight closures may be required later in the project, with details to be communicated in advance.

While buses will continue to operate, some may be diverted during overnight closures and certain stops may be relocated or suspended.

Julie Lewington, head of programme delivery at TfL, said: "Our plans to transform A23 Streatham Hill for everyone who lives and works in and visits the area will make it easier and safer for people to travel and enable more people to walk and cycle.

"We’re working to minimise the impact of construction work on local residents and people travelling through the area and would like to thank everyone for their patience during this vital project.

"We’re sorry for any disruption caused by the work and would encourage everyone to plan ahead using our comprehensive travel advice."

The full scheme is due for completion by spring 2027.

TfL said 70 per cent of respondents to a public consultation felt the project would make the area easier or safer to walk through, while 83 per cent believed it would improve conditions for cycling.

Cllr Rezina Chowdhury, Lambeth Council’s deputy leader and cabinet member for sustainable Lambeth and clean air, said: "We welcome this important investment in Streatham to improve the public realm and travel through the area, especially for people walking, cycling or relying on buses.

"I also welcome Transport for London’s efforts to minimise the impact on the area during the construction of this major scheme.

"We will continue to work with TfL to ensure local people are kept fully up to date as this project progresses."

TfL said it has planned the works to minimise disruption, including keeping traffic moving and limiting night work.

The organisation will continue to monitor the road network throughout construction and adjust traffic signals as needed to help manage congestion and support the bus network.
