A plan for superblocks has been implemented in Barcelona, which will transform 7 million square meters previously used for motorized vehicles into open spaces for the community. About 5,000 to 6,000 people are expected to dwell in each 400-by-400-meter superblock. The goal is to reduce pollution rates by 21 percent over the next two years.
The design was originally developed during the 19th century by Spanish urban designer Ildefons Cerdà to promote a healthy, urban environment. His idea inspired the new "mini neighborhoods" that have been developing in the city at various rates since the plans were drawn in 1987. By continuing this process for a greener existence, 160 intersections will be removed, 200 kilometers of biking lanes will be added, and an orthogonal bus network will encourage the use of public transformation.
