The work was normal up to a heightof 2700 m, but when greater altitudes were reached theworkmen could not work continuously owing to the so-called mountain sickness. During the two years of build-ing a total of 2400 workmen were employed. The illustra-tions show two portions of the road, one being a section ofa tunnel and the other a place where the road passes alongthe side of the mountain. The smallest radius is 80 m; the.

On a base having a width of m a layer ofbroken stone to a depth of .3 m and a width of m hasbeen laid. The tunnels are m wide and m above thehead of the rails. To gain some idea as to the cost of trans-porting material over the high altitudes without the use ofrailways, it might be stated that a cubic meter of buildingsand costs 62 francs at the lowest tunnel mouth.

There is only one80-m radius curve, which simplifies the construction. Therack between the rails is of the Abt type and can sustain apressure on the teeth of 6000 kg.
