On: Boring Company Will Expand Las Vegas Tunnels to 65-Mile Network

Then you'd have to repair the asphalt underground, at greater expense. What's the point? The hyperloop is one of the dumbest transport projects to ever be built.

[ianburrell → mjhay]

It is important to distinguish between the Hyperloop, the long distance vacuum tube, and Loop intra-city tunnels. They are very different and they are both stupid.

[mjhay → ianburrell]

Ah yes, I got those confused. I'm sure the naming is deliberate to conflate a dumb and non-exciting idea with a dumb but exciting idea.

[jandrese → mjhay]

Most asphalt damage comes from water getting under it and freezing. That shouldn't be a problem in a tunnel. But I'd assume they would use a concrete surface in any case.

[mjhay → jandrese]

Underground things are more susceptible to flooding, not less. That's why basements flood so much.

[jandrese → mjhay]

But they are far less susceptible to freezing. It's not the water that kills the road, it is the ice.

Well, water can erode away the material underneath the road, but if this is happening in your tunnel you have serious problems.

> and freezing

uh... is that why many roads in California are shot, too?

[jandrese → twelve40]

Californians just drive too much.
