Few tunnels get as much public attention as just the idea Elon Musk has to tunnel under Los Angeles to avoid traffic:
After being stuck in heavy traffic in December, the billionaire came up with a plan to create a giant tunnel under Los Angeles to ease congestion.
‘Traffic is driving me nuts. Am going to build a tunnel boring machine and just start digging…’, he tweeted…
Excavators working for the entrepreneur have already dug a test trench at SpaceX’s headquarters in Hawthorne, Los Angeles, Wired reported last week…
‘If you think of tunnels going 10, 20, 30 layers deep (or more), it is obvious that going 3D down will encompass the needs of any city’s transport of arbitrary size,’ he told Wired last week in a Twitter direct message.
I have a hard time envisioning how this could become useful for the general public. Musk would have to figure out something pretty spectacular to get the cost and time down. Or, one tunnel could open but it would be prohibitively expensive to use.
And isn’t there also an issue of freeing up land for entrances and exits from these deep tunnels? (Los Angeles might be a bit different if the tunnels are primarily for going through mountain passes.)
Boring machines broke through today at the opposite end of a 35.4 mile tunnel in the Alps, creating the world’s longest tunnel in Switzerland and taking the title away from Japan. While this is a feat of engineering (allowing high speed trains to carry cargo under the mountains rather than have it be shipped on trucks over the Alps), it is also interesting to read about the emotional responses people are having:
Trumpets sounded, cheers reverberated and even burly workers wiped away tears as foreman Eduard Baer lifted a statue of Saint Barbara — the patron saint of miners — through a small hole in the enormous drilling machine thousands of feet (meters) underground in central Switzerland.
At that moment, a 35.4-mile (57-kilometer) tunnel was born, and the Alpine nation reclaimed the record from Japan’s Seikan Tunnel. Television stations across Europe showed the event live…
Peter Fueglistaler, director of the Swiss Federal Office of Transport, called Friday “a day of joy for Switzerland.”
“We are not a very emotional people but if we have the longest tunnel in the world, this also for us is very, very emotional” he told The Associated Press.
This project is not just a boon for business and the environment; it is seen as a testament to the will and determination of the Swiss. As a project that has been in the works for decades (with the referendum votes for funding taking place nearly two decades ago), to see the proverbial “light at the end of the tunnel” is a big accomplishment. This is cultural moment that will likely become part of the Swiss collective memory.
How might the response in the United States to such an engineering feat differ?
