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.)
