superblock

noun

1. A very large block of buildings; in modern urban planning often designed for local needs, with access and speed restrictions.

   “All are blots on the urban environment, as blandly homogenous in their own way as the Modernist superblocks they were intended to improve on.”

   “Conceived as part of a 1950s-era slum-clearance program, the immense superblock required the demolition of an entire neighborhood of dilapidated tenements and brownstones.”

   “Superblocks are a relatively new urban planning concept that has been pioneered in Barcelona, Spain. The basic idea is to identify a 3 x 3 grid of 9 city blocks and restrict vehicle traffic to the streets on the perimeter. The interior streets then become available for walking, biking, and expanded green space.”

   “Barcelona’s flagship policy, which has attracted interest from around the world, is its superblocks, where groups of nine city blocks are transformed into people-friendly spaces, with benches, play areas and gardens. Cars may enter but cannot transit the superblock.”
