The Great West Hedge

The Great West Hedge is an innovative and challenging proposal to mark the launch of the London National Park City with a hedge along the Great West Road.

A protective and attractive hedge along the A4 to filter out some of the pollution for pedestrians, cyclists, residents and schoolchildren. Providing more green, a wildlife corridor, and improved street scene, and potentially filtering out some of the road noise.

Run as a Living Laboratory it would provide a London-based proof of the benefits of green infrastructure along roads for the improvement of air quality.

Where is it?

It will run from the end of the elevated section of the M4 through to the Hammersmith Flyover. Covering the entire length of the M4/A4 western “cut out” of the ULEZ October 2021 expansion (‘the unprotected banana’), and areas covered by the Chiswick and Hammersmith Air Quality Focus Areas, the hedge would run along both sides of the A4 from Chiswick roundabout to the Hammersmith flyover.

What does it look like?

We want the Great West Hedge to be a Living Laboratory, where the local community can work in partnership with public bodies and organisations in helping develop and prove in a real life environment the benefits of hedges for reducing urban pollution as shown by research.
