How do railways and highways cross the rugged terrain of the Apennines?

The Apennine Range presents significant challenges to transportation due to its rugged terrain, but these barriers have been overcome through extensive engineering efforts.

The range is traversed by several railway lines, some of which are double-tracked to manage traffic flow. Historically, many of these rail routes required the construction of long tunnels, which necessitated early electrification because steam power was ill-suited for such enclosed environments.12

Highways also navigate the mountains through the use of an imposing series of tunnels and embankments. A notable example is the Autostrada del Sole, which serves as the main artery of peninsular Italy and functions as a major scenic route. Additionally, other east-west highway connections, such as the route linking Rome to Pescara, have been constructed to cross the Apennines directly.13
