The bypass will take traffic from the B29 federal highway and relieve the strained city center of 20,000 vehicles a day. This was the state of planning in November 2013, when the first cars rolled over the new route with the two tunnel tubes. The underground structure, which is around 2.2 kilometers long, gained nationwide recognition during the name-finding phase, when hundreds of thousands voted for Bud Spencer Tunnel - the city's heraldic animal was chosen instead. It should be emphasized that the proAir paving along the road effectively combats air pollution caused by nitrogen dioxide.
