The Appenines are an approximately 1,500 km mountain range in ltaly.
Crossing them has always been a challenge. The Al freeway, which was
built in the 1960s, passes over them. The section between Florence and
Bologna is particularly dangerous due to tight curves. With more than 2,000 accidents in the last ten years, it has one of the highest accident rates of any ltalian freeway.
The Autostrade S.p.A. freeway company wants to improve both traffic flow and road safety with the Al freeway upgrade.
