A23 Streatham Hill London roadworks works until spring 2027

The A23 Streatham Hill in south London is undergoing a major redesign, with Transport for London (TfL) leading works to install protected cycle lanes and dedicated bus lanes.

The project is expected to continue until spring 2027.

A spokesperson said: "The new layout will improve bus reliability and make it easier, safer, and more pleasant for people to walk and cycle in the area."

The improvements aim to boost bus reliability.

Lane restrictions are currently in place in both directions between Holmewood Road on Brixton Hill and Sternhold Avenue on Streatham Hill.

The restrictions are expected to cause delays, particularly for drivers heading north.

Overnight closures are also planned between Christchurch Road and Sternhold Avenue to allow for changes to traffic management.

Signed diversions will be in place and Streatham Hill Low Traffic Neighbourhood restrictions will be suspended during these closures.

TfL advises all drivers to allow extra time for journeys and to check travel updates before setting out.

Parking along the A23 will be suspended for the duration of the works and some loading bays will be unavailable.

Deliveries are advised to be made outside of peak hours.

Buses will continue to operate along the A23, but journeys are likely to take longer during peak hours, especially on routes 2, 50, 60, 249, 250, 255, 319, 147, 432 and 468.

Some bus stops may be relocated or temporarily closed during the works.

Cyclists are encouraged to use signposted diversion routes, which are intended to be safer and quieter than travelling through the main works area.

Tube and rail services remain unaffected.
