Options for Vauxhall Cross Transport Area:
With the expected increase in population due to the envisioned new developments in the Vauxhall, Nine Elms and Battersea area, Vauxhall gyratory as the main transport interchange serving the area will experience a high increase in passenger / pedestrian footfall with the highest increase in movement being in the direction of the Nine Elms area. Traffic and public realm improvements will be required to upgrade the gyratory and interchange to improve pedestrian movement within the interchange area and to destinations around it. http://legacy.london.gov.uk/mayor/planning/oapf-nine-elms/docs/vneb-public-realm-study.pdf
