I wonder what the relationship is between the word engineering in the sense used here and software engineering?

I am amazed how bad software engineering has become with constant updates of software because of “improvements” or because there has to be constant release cycle else the software is unmaintained or bad.

While this kind of engineering is designed to be untouched for the next 15 to 30 years. Minimal maintenance is needed and certainly the concrete doesn’t need updating every second week because concrete has suddenly “improved” or there was a bug in it.

It’s become the norm to release bad software and fix it later, I hope this norm does not make it to real engineering.

That horrible website overrides web page scrolling and disables pinch zoom. Bad!

>over three times as long as the current frontrunner the 5.8-kilometre Transbay Tube in San Francisco

Are you drunk? the channel tunnel is 50km and it's not even the longest in the world https://en.wikipedia.org/wiki/Channel_Tunnel

edit: oh I see "immersed" tunnel. fine.

Can anyone from the region comment on the status of plans for the landside linkup on the German side? Last time it made the press it was because the project was at risk of seeing the Danish tunnel finished before Germany could tell not even when but if a linkup would ever make it across bureaucratic hurdles. Almost like a Darien Gap made exclusively of red tape.

Today I learned the Transbay Tube is the longest immersed tube in the world. Given that it opened in 1974, it presumably has held that record for 52 years!

> The Fehmarnbelt Tunnel will complete the high-speed rail connection between Stockholm and Hamburg.

Not really, mostly cause Sweden don't want to build high speed rail, even when EU would have paid for a big share of it.

I'm amazed that engineers can make submerged tunnels work and that leaks don't (literally) sink the whole plan.

52.6B krone for 18 km

8B USD for 11 miles

CACHSR IOS 36B USD for 171 miles.

The Merced to Bakersfield IOS looks like a bargain on a distance basis. I have no idea of the carbon offset or passenger time saving versus flying of course
