Further safety improvements at Bow roundabout

Closed 19 Dec 2012

Opened 28 Nov 2012

Results updated 31 May 2013

Following the public consultation, we have decided to proceed with the proposal at the westbound section of Bow roundabout with some changes to the cycle bus stop bypass. We have changed the design so the cycle lane is now at carriageway level throughout. A pedestrian crossing point will be provided via a raised table and will act as a speed table to slow cyclists down and also reduce the risk of conflict between pedestrians and cyclists.

Changes to cycle bus stop bypasses include additional road markings to alert pedestrians and cyclists to look out for each other and bus driver training. We will closely monitor Bow roundabout, especially trial designs such as cycle bus stop bypasses through on street surveys and video monitoring. We will make further modifications if required. We will continue to work closely with disability groups to further develop our designs for cycle bus stop bypasses

Next steps

TfL will now finalise the designs for the westbound section of Bow roundabout. The works to build the new improvements will begin in June 2013 and will open in summer 2013. The new improvements at Bow roundabout will be closely monitored once built.

Read the response to consultation



Transport for London (TfL) is working with interested parties - including cycling, road user and safety organisations - to review and improve cycling provision at junctions.

We recently consulted on proposals to further improve safety at Bow roundabout and consulted stakeholders and local people.

Having analysed the responses to consultation we have decided to make changes to some parts of the previous proposals. These changes are detailed in our Response to consultation, along with a summary of the responses. Further details can be found in the 'Results' section at the bottom of this page.


What we proposed and why

Bow roundabout is a key junction for cyclists travelling between central and east London. 

Cycle Early Start

A cycle early-start would operate at the traffic signals on the westbound approach to Bow roundabout.

This would provide a dedicated green light to allow cyclists to wait ahead of other traffic before moving onto the roundabout.

A new mandatory cycle lane on the westbound approach would allow cyclists to get to the roundabout entrance without having to filter through traffic.

The early-start area would be 18 metres deep, so there's a clear space for cyclists in front of any traffic.

This cycle early-start would improve safety, due to the reduced risk of conflict between cyclists travelling straight ahead and vehicles turning left. It would also provide a quick and direct route through the roundabout for cyclists.

The eastbound early-start was completed in June 2012. Our provisional monitoring to date shows that the eastbound early-start has been effective in reducing the left turning conflict risk that it was designed to address. It also shows that the cycle lane on the approach is well-used, with significantly fewer cyclists using the footway than before. We will continue to monitor and analyse the operation of these facilities.

Cycle Bus Stop By-Pass

TfL is proposing to introduce a new cycle lane around the back of the bus stop on the approach to the roundabout to help cyclists get ahead of other traffic and reduce the risk of conflict between cyclists and buses pulling in and out of the bus stop.

To accommodate the new cycle lane, the bus lay by would be filled in so buses would stop on the carriageway instead.     .

We continue to explore further improvements for cyclists and pedestrians as part of planned longer-term regeneration of the Bow area.
