Several columns of tractors set off this Friday morning from various points in Catalonia towards Barcelona. They arrived in the Catalan capital at midday and, since early afternoon, have been blocking Barcelona's Gran Via, where traffic is blocked from Plaça Universitat almost to Passeig de Gràcia. Many farmers arrived with their tractors and left them in the central lane, while others traveled in their own cars and parked in front of the Coliseum cinema, on the side opposite the headquarters of the Department of Agriculture.
