How Barcelona’s car-free ‘superblocks’ could save lives

Tierr@_de_N@die: The special urbanism of Barcelona with the streets distribution very marked by the 1860's Cerda plan, it eases the application of these super-blocks aimed to take the cars out of a big part of the city. 

By reclaiming 70% of street space from cars for pedestrians and cyclists in designated areas, the city could transform them into mixed-use public spaces or «superblocks» as they’re called. CityLab describes them as «square sections of the city’s grid made up of nine actual blocks, with a combined area of just under 40 acres, where through traffic is permitted only on perimeter roads.»
