Went to see a superblock in Barcelona. Given how much they feature as urbanism of the future, they are amazingly simple. Take an intersection, block traffic in all four directions and you have a square. Plant trees, add some tables and benches. That's basically it. Replace cars with trees and don't privatize the resulting space. All you need, and all that is usually missing, is political will.
@festal Nice to see they've got the walkways wide enough for two people using wheelchairs to pass in opposite directions. That can be rare.
