CS7 Upgrade Phases 1 & 2 - Balham High Road

Closes 31 Dec 2021

Opened 1 Jul 2020


Why are these temporary changes to the A24 necessary?

With social distancing requirements still in place on public transport, congestion levels across London will continue to rise if trips previously made by buses or trains were instead made by car. We must give people an alternative way to travel.

We completely understand that some journeys simply cannot be made on foot or with a bike. Many can, however. By helping people who can do so to walk or cycle more often, we can free up buses and trains for people who need them the most, and we can ensure our roads are as free-flowing as possible for the emergency services, businesses and buses and taxis.

Local people living between Balham and Colliers Wood tell us why they think people should walk and cycle

The NHS has found that there is a link between personal fitness and recovery from the coronavirus. An increase in trips made by car would also worsen the quality of our air and increase road casualties from collisions. We’ve said previously that in the last three years up to December 2019, 126 people cycling on the A24 were hurt in collisions. 19 people were seriously injured. 

An increase in trips by car will add congestion to your roads, delay local bus services, increase air pollution, increase road casualties and delay essential emergency services. More traffic on London’s roads is not the solution to help London recover from the pandemic, but active travel through walking and cycling is.

- update ends -

As London continues to emerge from the lockdown we will need to help people to walk and cycle more often, to reduce demand for public and private transport to essential trips only.  

We are temporarily upgrading Cycle Superhighway 7, as part of our plan to create a cycle corridor to follow the Northern line from Colliers Wood to Elephant & Castle. The first phase of our work will focus on the section from Balham to Colliers Wood.    

Our works to build the temporary improvements on a section from Balham to Tooting Bec will be completed by 7 August. The works on the section from Tooting Bec to Colliers Wood will begin on 3 August and will be completed by the end of August.  

The maps below give an overview of the changes we will be making.

The temporary changes we will be making are:  

  • New lightly segregated cycle lanes using cylinders
  • Bus stop bypasses for cycles wherever possible which will also provide further footway for pedestrians
  • Existing bus lanes will be converted to 24/7, except for the bus lane between Totterdown Street to Mitcham Road southbound which will be 07:00 - 19:00
  • Bus lanes increased across the scheme by 190m. A section of bus lane is however being removed southbound between Ritherdon Road and Tooting Bec Road to provide cycling facilities and a new 24 hour bus lane created between 215 Balham High Road to Ritherdon Road southbound. Further small increases in bus lane length throughout the scheme
  • Improved footway to allow social distancing along Balham High Road, Chestnut Grove and at the junction of Mitcham Road/Tooting High Street
  • No entry (except cycles) from A24 onto Balham Park Road, Dafforne Road, Noyna Road, Fircroft Road, Foulser Road, Topsham Road, Mandrake Road and Ansell Road
  • No right turn onto A24 (except cycles) from Trinity Crescent, Dafforne Road, Noyna Road, Fircroft Road, Foulser Road, Topsham Road, Mandrake Road, Brudenell Road, Lynwood Road, Gatton Road and Selkirk Road
  • No left turn from A24 into Trevelyan Road
  • No left turn (except cycles) from A24 onto Chestnut Grove, Brudenell Road, Lynwood Road, Derinton Road, Woodbury Street, Gilbey Road and Sellincourt Road
  • No left turn (except cycles and buses) from A24 onto Ritherdon Road and Balham Station Road
  • No right turn (except cycles) from A24 onto Totterdown Street
  • Multiple parking and loading bays will be removed from A24. Most loading and disabled bays will be relocated to nearby side roads. On side roads you will be able to load in marked bays between 10:00 - 16:00 Monday to Sunday for a maximum time of 20 minutes. Disabled bays will be in operation for a maximum of 3 hours  

These are described in more detail in the pack of maps below.

Although we are not undertaking a formal consultation on any Streetspace schemes, we would like to know about your experiences of them. If you have any comments about the effects of our scheme, or suggestions for changes or improvements we might make, please let us know at: streetspacelondon@tfl.gov.uk 

We will continue to monitor the effects of these temporary changes over the coming months. This includes their effects on traffic flow, road safety and cycling and walking rates. We have written to local people, businesses and other stakeholders to explain what changes we have made and encouraged them to provide us their views and experiences of the changes. We will listen carefully to the feedback we receive.
