Why have the streets been painted in different colours?
These actions correspond to tactical urbanism. Paint and signs are used to quickly adapt public space to needs which arise, as is the case with the pandemic. When long-term work is considered necessary, a definitive transformation is the next step.
Tactical urbanism has saved thousands of jobs in recent months by extending restaurant and bar terraces, introducing traffic-calming measures in streets, reducing noise and pollution, protecting schools and gaining more public space for people. It forms part of a medium-term project and will be extended citywide to improve quality of life, reduce pollution and stimulate the neighbourhood economy, with the so-called Barcelona Superblock model.
