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
Here's a similar video for BART's Transbay Tube, which was built in a similar way.[1] The major differences come from building in an earthquake zone. The Transbay Tube is mostly steel, rather than concrete, for flexibility. There are expansion joints. And the Transbay Tube sits on a gravel and sand base rather than hard rock, on purpose.
The Transbay Tube sections were built in the Bethlehem Steel shipyards in San Francisco.
A museum opens this month to commemorate that shipyard. It's in Dogpatch in SF, if you know the area. The shipyard still has a submersible drydock, but it hasn't worked in ten years and will be demolished soon, hopefully before it sinks.
The SF Bay Area once had far more heavy industry than most people realize.
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!
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.
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.
Hmm, website owners can apparently mess with my settings and make their site "smooth scrolling". Ugh. It's like having a nightmare where I'm trying to scroll as hard as I can but I feel like I'm scrolling through mud.
It actually feels like they have a speed limit to scrolling, I'm used to giving my MX Master 3S a big spin and being at the bottom of a page near instantly, here it takes time.
I worked for a company on a job in New York harbor surveying a 9ft diameter sewage tunnel that runs from Newark under Bayonne to New York Harbor (there is a vent near the little lighthouse you pass on the Staten Island Ferry). There was concern that some of the dredging would lighten the load over the tunnel and the tunnel would pop out of the ground.
This is very exciting if you live in the Copenhagen–Malmö area. Currently it takes 5 hours from Copenhagen to Hamburg, and 8 hours if you want to get to Berlin. With this tunnel done, I believe Copenhagen to Hamburg will be less than three hours. Suddenly a weekend trip to Germany by train looks more practical. The train is very nice right now, but you need to set aside a day for travel, in both directions.
It's a shame that the legacy of the Cold War means that Hamburg is “closer” by rail than Berlin, even though if you look at a map you can see it shouldn't be. If they had built a tunnel to Rostock, things would have been different…
And here I am measuring the distance from Dublin (Ireland) to Holyhead - would be ok for fast rail, but then it's between 3 to 5 hours of rail to London.
I wonder if Ryanair pays rail companies to offer poor service.

(german source ... and very critical of the project)

Personally I like the concept of having a more direct access to scandinavia and see lots of other positive long term effects.

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.

The four leading crossing options would be the Kintyre (most northerly), Galloway, Irish Mail, and Tuskar (most southerly) routes.
Irish Sea depths (notably Beaufort's Dyke), and unexploded and chemical ordinance, are principle concerns.
