Competition entry, shortlisted 2012
The post-war drive to build high-speed motorway-standard roads resulted in more than 30km of elevated road in built-up areas of Central London. Our design proposes to transform these elevated roads into productive and beautiful green arteries by wrapping flyovers in a biodiversity overcoat able to accommodate a wide range of planting and wildlife. This design would improve air quality, reduce the impact of traffic noise and heat sink effect, and allow biodiversity to flourish. Implementing Green Arteries on elevated roads in Central London would yield approximately 35 hectares of planted space, equivalent to 55 football pitches.
