The Green Slinky

The Green Slinky for Blackfriars Bridge would separate road users, create new habitats and add a sense of drama and delight. By extending the redevelopment of Blackfriars station, viewing gardens accessible from the station platforms could be constructed on the pillars that were once the foundations of the old bridge.

The Green Slinky

A 280m planted tunnel could make Blackfriars Bridge safer for cyclists

The Green Slinky proposes both a new London landmark and a radical approach to safely separating different groups of road users on Blackfriars Bridge. 

For some time, cyclists have campaigned for better traffic separation over the bridge following well-publicised accidents. Critics say attempts to separate different traffic streams within the existing road set-up are flawed and that the bridge is still dangerous for bikes.

But the Slinky, which would be a 280m undulating, planted tunnel and cycle way in the centre of the bridge, aims to tackle the problem by separating cyclists from buses and cars. Furthermore, a green wall would run along the edges of the pavement to separate pedestrians and vehicles. Regular gaps in the green wall and the slinky would create crossing points and views across the bridge and down the Thames.

Other bridges in London could also transformed under the proposals. For example, pedestrians could be separated from traffic on Waterloo Bridge by wavy green walls and magnificent 375m-long ornamental grass beds.
