What's changing?

Willow Tree Roundabout is one of the top 150 most dangerous junctions in London. The roundabout is intimidating, with a history of drivers approaching at high speed and failing to give way. Between April 2019 – April 2024 there were 35 collisions, resulting in 42 personal injuries including four serious injuries, and we are aware of an incident in June 2026 in which tragically a pedestrian was killed following a collision with a large goods vehicle.

To encourage lower speeds, we will add new ‘Reduce Speed Now’ signs, countdown markers ahead of the give-way lines, additional ‘SLOW’ road markings, and tall shrubs on the roadside near the give-way lines.

These proposals are illustrated in the map below.

Installing these signs and tall shrubs will help encourage drivers to slow down to observe oncoming traffic as they merge onto the roundabout.

We will also trim back overgrown bushes to ensure existing signage is clearly visible.

These works are part of Transport for London’s Road Safety Programme, which aims to reduce vehicle speeds, enhance driver awareness, and improve safety for pedestrians, cyclists and drivers so no one is killed or seriously injured on our roads.
