Safer Junctions - Clapham Road and Union Road and Clapham Road and Stirling Road

Closed 25 Jul 2019

Opened 12 Jun 2019

Results Updated 24 Oct 2019

We recently consulted on proposals at the junction of the A3 Clapham Road with Union Road.  

We received 72 responses to the consultation, 65 from members of the public and seven from stakeholders, thank you to those that responded. 49% of respondents stated that they would feel safer or much safer when walking around the junction and 60% of respondents when cycling.  

Following the consultation, we are planning to implement the scheme as proposed. We will work with local stakeholder to start construction as soon as possible, with the aim of completing the scheme by March 2020. We will also continue to work on plans for more substantial upgrades to Cycle Superhighway 7, including this junction.

We would like to know your views on proposals for the junctions of Clapham Road and Union Road and Clapham Road and Stirling Road, in Stockwell.


Our Safer Junctions programme is reducing road danger at some of the most hazardous junctions in London. These junctions have high collision rates for vulnerable road users, including people walking and cycling. This programme directly contributes to our Vision Zero target to stop people from dying and being seriously injured on London’s road network by 2041.

The objectives of the Safer Junction programme are to:

  • Reduce road danger and help eliminate Killed and Seriously Injured (KSI) collisions
  • Help create streets where people feel safe to walk, cycle and use public transport
  • Make hostile junctions more welcoming and less dominated by motor vehicles, demonstrating the Healthy Streets Approach

Why we are consulting

In the last three years, there were 23 collisions at this junction, 18 of which were people cycling. (Data available up to 30 September 2018).  

A number of issues have been identified with the current junction layout:  

  • Difficult for road users to turn right from A3 Clapham Road into Union Road. People making this turn are allowed to proceed at the same time as the A3 northbound traffic is moving, leading to right-turning drivers seeking short gaps in the traffic and turning impatiently or without enough care.  People cycling northbound nearer the kerb may be hidden by other vehicles, increasing the risk of them being struck.
  • Northbound cyclists vulnerable to left-turning traffic. There are a lot of cyclists heading north into central London in the morning peak. Drivers turning left into Union Road have to cross this flow of cyclists.
  • Advanced stop lines (ASL) for cyclists at the junction are too small. The number of cyclists using the junction at peak times means the ASL boxes can not safely protect everyone cycling, particularly people cycling northbound along Clapham Road in the morning peak.
  • Poor junction alignment with Stirling Road. Many vehicles turn right from Stirling Road onto the A3 and then turn left into Union Road, cutting across two lanes of traffic including cyclists. 

This junction is on the existing CS7 cycle route. Shortly, all high-quality new and existing cycle routes in London will be incorporated into a single unified cycle network, known as Cycleways. As part of our work to roll out the Cycleways network, we will be assessing all completed routes including Cycle Superhighways against new quality criteria, including CS7 and this junction. Where a route does not meet the quality criteria, we will consider whether any upgrade work is feasible to bring it up to the required standard, subject to funding. We therefore consider the below proposals to be an interim safety scheme whilst we review the entire CS7 corridor.

Our proposals

We would like your views on the following proposals which aim to reduce the above issues and collisions.   

  • A separately controlled right turn from A3 Clapham Road into Union Road. Drivers turning right will be held at a red signal while northbound traffic moves, completely removing the potential for right turn conflict.
  • An earlier green signal for northbound cyclists from the junction. This will allow northbound cyclists to be clear of the junction before other vehicles move, reducing conflict.
  • Reallocate northbound traffic lanes, with the left lane for left turning vehicles only and right lane ahead only.
  • Reallocate southbound traffic lanes with designated lane markings for ahead and right turning movements. This will allow free flow of southbound traffic without having to wait for right turning vehicles to clear the junction.
  • Ban the right turn from Stirling Road into Clapham Road, except for cyclists.
  • Extend all cycle Advanced Stop Lines (ASL) to 7.5m in depth.
  • Change the kerbs on Union Road to increase footway space for pedestrians. This will also reduce the junction width so that cyclists will have a shorter distance to travel through the junction.
  • Help people walking across the junction by widening the existing pedestrian crossings.
  • Include a half-inset loading bay on Union Road to allow deliveries to local shops and businesses to continue.

Next Steps

Following this consultation we will analyse the responses and review the design. We will then seek the necessary powers and, subject to this consultation, are planning to implement this scheme in early 2020.

Healthy Streets  

The changes proposed in this scheme are part of our commitment to deliver the Healthy Streets Approach. We are taking this approach to create a vibrant, successful city where the streets are welcoming to all and everyone can live active, healthy lives. The streets within this scheme and the proposed changes have been assessed by our designers against ten Healthy Streets Indicators using our Healthy Streets Check for Designers tool. This tool assesses the layout of streets against thirty one measures which produce an overall Healthy Streets Check score out of 100. We use infographics to show the current score for the streets within this scheme and potential scores based on our proposed changes. The Healthy Streets results can be seen in the diagram below.

Equality Impact assessment

We are subject to the general public sector equality duty set out in section 149 of the Equality Act 2010, which requires us to have due regard to the need to eliminate discrimination, advance equality of opportunity and foster good relations by reference to people with protected characteristics. The protected characteristics are: age, disability, gender reassignment, marriage and civil partnership, pregnancy and maternity, race, religion or belief, sex and sexual orientation. As part of our decision-making process on proposals for new schemes, we have had due regard to any impacts on those with protected characteristics and the need to ensure their interests are taken into account.

In considering the design of our streets, we closely consider the needs of all users throughout the design process. As this scheme is a significant infrastructure project we:   

  • Have completed a draft Equality Impact Assessment (EqIA) at the outset of the project, to review potential impacts on equality target groups, including disabled people
  • Are carrying out public consultations, including targeted engagement with accessibility user groups 
  • Will continue to ensure we comply with established guidance – such as the Design Manual for Roads and Bridges – which includes detailed requirements for disabled people

A draft EqIA has been carried out for the proposals that we are consulting on. While the changes we are proposing are broadly positive for all protected groups, the assessment highlights some negative impacts during construction for some vulnerable groups. This is because during construction the junction and pedestrian crossings could change. These impacts would be reduced as much as possible, with signage of possible alternative walking routes around the junctions. However, this could cause longer journey times for people during construction. A full copy of the draft EqIA can be found below.
