The mythical comic characters Mortadelo and Filemón already control traffic at a traffic light in Barcelona, ??marking red and green with their silhouette, in a permanent tribute to their creator, Francisco Ibáñez.

The first of the four traffic lights that these characters will have is at the intersection of Treball Street and Concili de Trento, in the Sant Martí district, where Ibáñez lived and in front of the award-winning Gabriel García Márquez library.
