The ‘Green Bridge’ design by biomorphis in Leith Walk, one of the key thoroughfares in Edinburgh, Scotland, aims at bringing a lightweight structure with low embodied energy. Construction materials based on plant products represent the way forward in terms of diminishing our dependence on hydrocarbons. Leith Walk, which unfortunately acts as a major divider, needs a bridge which would link the East cycle paths to the West of the city. It would redirect the ever-growing flows of bikes and pedestrians and also become a landmark for the community. More images and architects’ description after the break.
