Next phase of work begins on 29 June, with overnight closures and traffic reduced to one lane in each direction until August
Scheme will deliver protected cycle lanes, new pedestrian crossings and continuous bus lanes to improve safety and journey times
Customers advised to plan ahead as journeys are expected to take longer during this phase of works
Work on the next phase of improvements on the A23 Streatham Hill will begin at the end of the month, with temporary traffic restrictions in place while the scheme is delivered.
From Monday 29 June, phase four of the project will see the construction of new central islands as part of a wider transformation of the road. These will provide safer waiting areas for pedestrians crossing the road and help separate traffic flows. The improvements will include protected cycle lanes, new pedestrian crossings and continuous bus lanes, designed to reduce road danger and make it safer and easier for people to walk, cycle and use public transport.
Overnight closures will be in place between 22:00 on Sunday 28 June and 05:00 on Tuesday 30 June, between Christchurch Road and Sternhold Avenue. This will take place across two separate overnight closures: from 22:00 on Sunday 28 June to 05:00 on Monday 29 June, and from 22:00 on Monday 29 June to 05:00 on Tuesday 30 June. The first closure will affect the southern section of the scheme (Sternhold Avenue to Telford Avenue), while the second closure will cover the northern section (Telford Avenue to Christchurch Road). These closures are taking place during the summer period when traffic levels are normally lower, and they’ve been scheduled to avoid other major roadworks where possible. The plan aims to minimise disruption to users as much as possible.
From 05:00 on Monday 29 June until August 2026, traffic will be restricted to one lane in each direction. Daytime works for this phase are expected to complete by 9 August, followed by a period of overnight resurfacing works later in August. People travelling in the area are being advised to plan ahead and allow more time for their journeys. There will also be temporary changes including bus stop relocations, side road closures, pedestrian diversions and parking suspensions. TfL is encouraging people to walk, cycle or use public transport during this time and for drivers to consider alternative routes.
