Two stages in the second half of the Giro had their courses altered shortly before they were run. The more notable was stage 14, which had been hyped as the début of the Monte Crostis in the Giro d'Italia. Commissaires from the UCI mandated it be removed the night before stage 14 was run. The Crostis is not a well-maintained pass, and Giro officials had set out a detailed protocol whereby team cars would not follow the race up or down the mountain, and only motorbikes offering wheel changes would be present with the riders. Team managers expressed concern that they would not fully be able to fulfill their duties if not present with the riders like normal, and this was given as the basis of the UCI's decision. They held that Giro organizers had sufficiently ensured rider safety on the course, but the necessary protocols did not protect the sporting aspect of the race. Thus, the Crostis was eliminated, and the stage was reduced in length from its originally planned length of . The second-category Tualis climb was added to the route for the day to offset the loss of the Crostis. However, protests from spectators disappointed by the removal of the Crostis part of the route, including many who had volunteered for works to make parts of that road safe, led to the cancellation of the Tualis climb. The route was diverted while the stage was in progress to avoid a small village at the foot of the Tualis where protesters had gathered. Therefore, the length of the stage was shortened to . The Giro's last stage, an individual time trial in Milan, was also shortened. The course was shortened by four days before the stage took place, due to a special election taking place in Milan the same day as the stage. City officials expected high voter turnout and did not want the city center tied up by the race all day, so the revised route began at the outskirts of Milan instead of its center. It still ended, per its original design, at the Duomo di Milano.
