Socialist Government's handbrake on the ambitious plan to create deterrent macro-parking lots - or park and ride, in its English name—which had been designed by the previous government of Junts and ERC and which was intended to relieve car congestion in Barcelona. The obvious failure of the first of these macro-parkings, which was inaugurated last summer in Martorell, has led Salvador Illa's executive to halt the thirty projects that had been started and to rethink the need for these large infrastructures, which were supposed to be a stimulus to improve mobility and reduce pollution in the metropolitan area.
