Figure

1, it illustrates the Mont-Blanc road

tunnel

, which is 11.6 km long from the French end to the Italian end. The

tunnel

has been bored through a mountain range which rises up to a maximum of 3.5 km above the

tunnel

, at a point closer to the French entrance than the Italian. The

tunnel

was built between 1957 and 1965. As shown in

Figure

2, the Seikan rail

tunnel

,

on the other hand

, took more than five times longer to construct, from 1946 to 1988. It was constructed under the Tsugaru Strait between the cities of Hakodate (Hokkaido Island) and Aomori (Japanese Island). The

tunnel

is 53.85 km in length, equal to almost five times the length of the Mont-Blanc

tunnel

. It is 240m below sea level at its maximum depth.
