during saturdays, sundays and public holidays, the city council of bologna has implemented a policy closing via ugo bassi, via rizzoli, part of strada maggiore and half of via indipendenza to regular traffic, with routes 13 and 14 travelling through via ugo bassi (13, 14), via rizzoli (13, 14) and strada maggiore (14). as a result, route 13 is divided into two branches, one starting in via lame to borgo panigale and the other one starting from piazza cavour to san ruffillo (via pavese) and rastignano. trolleybuses are used only on the branch between via lame and borgo panigale, with the trolleybus poles being lowered for the short distance between via san felice and via lame. route 14 is diverted on its eastbound routes through via marconi, via dei mille and via irnerio, and therefore cannot use trolleybuses due to the potential damages these vehicles can face when running on their own engines for long distances.
