The figures compare the cross-sections of two tunnels. Figure 1 illustrates a road tunnel joining two European countries, while Figure 2 shows a railway tunnel linking two islands in Japan.
Overall, the two are completely different in terms of length, geography and the time span required to construct them. In addition, one is for road transport and the other rail.
According to the 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.
