Just a thread for everything about tunnels and tunneling. International, national, local... rail, road, anything else...

Looks like Elon Musk is taking his mysterious tunnel tweets to a new level.

Maybe Musk will invent better tunnel boring?

He very well might, but I'm reasonably sure that the reason we don't have subways everywhere is that it would take too long to dig the tunnels. Boring speed isn't the limiting factor.

A PBS documentary on the historical push to get rail lines underground.

Turns out the blizzard of 1888 was the biggest trigger, dumping many feet of snow in places shutting transportation down all over.

Like hyper loop and self driving technology, this tunneling nonsense will only look feasible if the most challenging aspects are ignored.

Tunneling isn't nonsense in Seattle right now, at least for transit rather than SR99.

Yes, but musk and his fanboys won't revolutionize tunneling.

Seems like a good time to readdress my [admittedly bonkers] deep bore I-94 plan. Hmmmm...
The problem with being an introvert online is that no one knows you're just hanging out and listening.

Angie Schmitt at Streetsblog really down on Musk's idea of tunneling to reduce highway congestion.

With bonus call out to a streets.mn blog post about thoughtful legislation.

The assumption seems to be that Musk wants to tunnel for roads (highways), when building more subways is the far more practical and likely result of any tunneling technology improvements.

I think I agree. Seems he's using his tweets to drum up interest in general. In the way that everyone assumes discussions around reducing congestion must mean getter options for getting around in cars. There could be a fair chance this won't involve cars.

This isn't specifically about tunnels, though tunneling costs make a major point of the article. Alon Levy writes in The American Interest, "Why We Can't Have Nice Things". His thoughts on why infrastructure costs are so high.

http://www.the-american-interest.com/20 ... -things-2/

Many have looked at why US costs are so far above other western nations, in this he points attention at early 20th century reform laws that solved problems with corruption and graft. He believes that today there are better ways to conduct oversight that doesn't have to slow things down and cost as much.

Another week and more about Elon Musk's "The Boring Company" has another profile.
Musk says he hopes to build a much faster tunneling machine and use it to dig thousands of miles, eventually creating a vast underground network that includes as many as 30 levels of tunnels for cars and high-speed trains such as the Hyperloop.

Well, that answers Tiller's question about why everyone assumes that Musk is talking about tunnels for cars.


And also confirms that he still is under the impression that the limiting factor on infrastructure construction is "ability to construct the infrastructure".

Wasn't really a question, but that quote is gross. Thank goodness a multi-level tunneled road system is beyond impractical.

They should keep all the parking in the tunnel, too. Some folks could start living like Edgar Friendly.

Norway wants to build a ship tunnel...
