Part 5/8:
The third proposal is a tethered tunnel system. Here, the tunnels would be situated 150 to 200 feet below sea level, secured by strong cables akin to those used in suspension bridges. This scenario aims to account for incidents from marine life, potential sabotage, and environmental factors.
A Glimpse at Existing Tunnel Engineering
Reflecting upon current tunnel engineering marvels, Musk can take inspiration from the Gotthard Base Tunnel in Switzerland, which, at 57 kilometers long, is the world’s longest and deepest railway tunnel. However, historical challenges reflect the hurdles that come with such undertakings, such as the recent derailment that forced the tunnel closure for an extended period.
