Only 175 km (108.7 mi) of this 666-km (413.8 mi) highway are covered with bitumen,
and one has to drive the rest of the way on gravel. There are only 3 settlements,
3 refueling stations, and only 1 medical center throughout the highway. The local
police force checks the presence of everything necessary for survival in
the difficult Alaskan conditions for everyone who enters this route.
[14] "Train to the Clouds," Argentina
During the 217-k (134.8 mi) railway journey, the train passes through 21 tunnels,
42 bridges and viaducts, 2 spirals, and 2 more zigzags. Its romantic name was
given to the road thanks to the altitude on which some of its segments are located:
sometimes it’s so high that the trains pass right through the clouds.
