What the english version of this wikipedia article doesn't mention (the german version does) is that the usage of this tunnel shifted a lot in recent years.
Today it's a very important bike route for people living south of the river Elbe (especially in the districts Wilhelmsburg and Veddel, both experienced heavy gentrification in the last two decades).
While the english version only states yearly usage numbers for 2008 (300k cars, 63k bikes, 700k pedestrians) the german also has numbers for 2018 (52k cars, 300k bikes, > 1 million pedestrians).
In my own experience the pedestrians are mostly tourists and the cars people working at the shipyards south of the river Elbe.
I witnessed a lot of conflicts between pedestrians for which crossing the tunnel is some kind of special experience getting in the way of cyclist which just want to get from one side of the river to the other as quickly as possible. There are sidewalks on both sides of each tube but tourists don't care much.
But I guess this is kind of inevitable if such a curiosity is part of the daily used traffic infrastructure.
Wondering if it was used for wartime production, for protection from bombings.
German aircraft production increased each month right up until substantial homeland territory was lost, apparently unaffected by massive bombing. Given its military futility, most of the bombing should probably be considered war crime. Air crews' lives were squandered.
Unlikely. Parts of it are above the river bed, and stick out into the water. It's all rather fragile patchwork, not some massive reinforced concrete thing.
This sticking out is also the reason all the terminals for larger ships are downstream of it, because their keels would crunch it, even at high tide.
When I was constructed, the tunnel did have 3m of sediment on top of it. This was required, as the tunnel was dug horizontally. Unless that changed over time, no part of the tunnel should be exposed.
I do know that. But I think the graphics in Wikipedia visualizing the profile are wrong. I've been into exhibitions about it, which showed much more than that. Also it may have been different at different times because the river is dynamic, has been and is been dredged out, from time to time, as necessary.
The roof of the tunnel is too high in the water, to let contemporary large ships
pass. Where large ships means the giant container freighters with 19.000+ TEU capacity. Mission impossible. Covered or not. This is not true for roll on/roll off ferries, or some cruise ships which seem similarily large, but aren't, at least not below the waterline. They just manage, but barely.
It is a barrier inhibiting ships with large draft/draught from passing. Which is why all the terminals servicing them are downstream.
I dont know about the use as a shelter, but you might be interested in the fact that one of the largest german shipyards Blohm & Voss is right at the south side of the tunnel.
I've been there. It's very f*** cool. It's sort of like the old underground metro subway stations in Sydney australia. You know the old circular key line with Martin place museum Hyde Park these type of stations on them? I can't remember all the names now but they have that old tiling and the long pedestrian tunnels and I mean just a fantastic kind of vibe to go into them and this tunnel is like that but it goes under the water.
I think there might be a similar tunnel in Antwerp, Belgium (great city, awesome Jewish bakeries) I seem to recall having transited such a place in that region too.
Of German tunnels I've always found the Zugspitzbahn impressive. The last section is a tunnel through the highest mountain of Germany and ends 300 meters below the summit.
Was interesting to go through, the tiling is old school, and they've preserved the old car lifts, they're positively Steam Age looking steel girder contraptions.
However, for true balls, you have to look at the French who completed the incredible Haiphong to Kunming railway, mainly to extract tin. https://en.wikipedia.org/wiki/Kunming%E2%80%93Haiphong_railw... Incidentally, I just purchased some bulk solder which is still being produced from Yunnanese tin today. The town was mined so heavily the center collapsed and turned in to a craterous water feature. https://en.wikipedia.org/wiki/Gejiu There's a mining company museum which features an early computer imported from the US (I have photos somewhere), possibly off the back of US-China anti-Japan collaboration during WWII, which was significant in the area. How times change!
The English of course wouldn't have it and tried to beat the frogs by bringing a line in from Myanmar with the support of the US but failed. https://en.wikipedia.org/wiki/Yunnan%E2%80%93Burma_railway You can read the minutes of them pompously pontificating in London. It would make a great film, IMHO. China has recently rebuilt the French line as a high speed line to the border, from which travelers may appreciate the relative infrastructure fail that is north Vietnam.
There's something about underground infrastructure that really intrigues me, despite how claustrophobic it can feel if I start thinking about what lies above.
I find it really interesting in this tunnel there are lifts for cars, because the entrance/exit points are vertical drops to the tunnel.
Biked through the tunnel, then ran over the Köhlbrandbrücke the one time a year they let you do that. The fun one can have pointlessly crossing a river (:.
While it has low capacity and was "replaced" with other ways to cross the Elbe, it still helps ease traffic across the river, other roads and bridges are often very packed or even blocked (often WW2 bomb defusals). I have lived both in NYC and in Hamburg and while the scale in Hamburg is way smaller, the type of traffic is kinda similar. Btw, isn't the Holland tunnel from NJ to Manhattan also free?
Also, we generally don't have tolls anywhere in Germany. If we do I have a hard time thinking of examples. Our taxes are (too) heavily invested in road infrastructure anyways and the tunnel isn't privately owned.
Right now the "Alte Elbtunnel" is undergoing maintenance in one of the two tunnels. Since as long as I've lived here, it hasn't been open to cars, but the large elevators previously used for cars are still serving bicyclists and pedestrians during the daytime. They get quite full during rush hour.
Many of the older subway stations in the upper part of Manhattan were built in the same time period and have a very similar architectural style, down to the tiled walls and the ornate molding, but they look absolutely decrepit. The tile is stained with dirt and grime. The molding is broken in places.
For most people who pass through one of these stations (which are pretty busy), their general impression is that the stations look cheap and dirty. You wouldn't really notice how lavish the decorations in these stations must have been at opening unless you were paying particular attention to your surroundings. It's sad how little the US has invested in maintaining its public transit infrastructure compared to other countries.
> It's sad how little the US has invested in maintaining its public transit infrastructure compared to other countries.
I'm on the fence about this, on average across the US, I'd agree. But where we do have decent transit, we seem to spend a lot. The NY MTA will spend $18B[1] in total in 2022, more than 6x the amount the state spends on all state roads in NY for 2018[2]. Despite this amount of money being spent, we have the general problems that you mention above, plus the fact that any expansion is prohibitively expensive. I just have to wonder, even if a lot more money were spent, would we actually see proportional improvements?
I do not live in NYC, so please correct me if I am wrong, but both can be true at the same time.
Looking specifically at the NYC subway, they are both over-spending and under-spending at the same time. In a nice example of the Boots Theory[0], they are spending money by the boatloads to keep the dating infrastructure working. A lot of it dates back to the 1930s, and it is impossible to get replacement parts. A newer system would be far easier and cheaper to maintain - but in the short term replacing it would be an enormous cost.
This is made even worse by it running 24/7. Without a maintenance window, doing proper preventative maintenance is pretty much impossible.
I never heard of the Boots Theory before now, but I don't think it applies to the MTA. They buy the top of the line. And will build their own parts if it doesn't exist. It's not unusual for subway cars to run for millions of miles and last decades. The R32's were deployed in the 1930's and lasted until the early 2000's [0].
I am a New Yorker, and have seen the MTA do maintenance at night or over a weekend. Or, if things are desperate, during the day.
I don't know the real issues either, but always assumed politics played a big part.

That doesn't seem to contradict th idea that they've spent far more money maintaining obsolete equipment when buying new would be cheaper overall. (Not really "boots theory" though).
It’s worth noting their entire switching infrastructure is human run mechanical switches and the tech are dated enough the MTA can’t even reliably know where a given subway car is. By comparison, most subway systems have a computerized switching infrastructure with real time computerized tracking of cars, saving quite-literally millions of man hours a year of work.
A lot of the MTA's budget is spent on interest on their debt (about $4 Billion / year). Page 23 of your report shows they currently have about $45 Billion in outstanding bonds. A cursory view seems to show about $6 Billion is to cover capital projects, which makes one wonder what the other 39 Billion was issued for.
“One big chunk of revenues, about $5.5 billion in 2013, comes from fares, which has steadily increased since in the last decade on the back of growing ridership and two fare hikes. But it’s been nothing drastic.
Instead, the drama has come from the other major component for the MTA’s revenues: taxes, grants and subsidies that are routed through the city and state governments. In 2013, for instance, “grants, appropriation and taxes” brought in about $5.3 billion in revenues.
Large components of these revenues are linked to taxes levied on real-estate transactions in New York. The Mortgage Recording Tax is among the prime sources, collected in New York City and the seven other counties within the MTA’s service area. 30 cents per 100 dollars of recorded mortgages, and 0.25 of one percent of certain other mortgages, are paid into this.
In 2005, before the great recession, it raised $1.3 billion. And in 2009, in the depths of the great depression, it raised $350 million. It’s hard running an agency, especially one so big, with such volatile revenue sources,” explained Russianoff. “The others don’t come close to the Mortgage Recording Tax but they have their volatility as well.”
[…]
But the same manpower is also turned into a sort of liability, partly due to the MTA’s own doing.
“All the benefits have begun costing a lot and the MTA, for a long time, had a deal where they would basically give retirement benefits after 10 years,” explained Jain. “So people would go find other jobs, or they would retire and go find another job. And when the time comes, they’d be collecting retirement benefits.”
It's tempting to see it that way, but I read your comment and see an unfair comparison between a small city and the largest in the United States. The MTA is ugly (I love it) but let's not kid ourselves, they spend a shitload of money maintaining nearly 500 stations, probably the yearly cost of that tunnel per day.
No -- but NYC is a very large city. So comparatively, Hamburg is small.
City to city comparisons can be tricky because city borders vs metro area can be a bit arbitrary, but no matter which way you cut it NYC is vastly more populous.
The (at least the older original) stations of the Moscow metro are likewise individual works of art. The pure plain utilitarianism of modern stations in NYC or the London Underground are sterile and boring in comparison.
I don't think "pure plain utilitarianism" is a fair description of the London underground as a whole. Even the Victoria Line made a point of doing a unique mosaic for each station; the Jubilee Line extension has a distinctive artistic style (which a lot of people hate, but you can't say they didn't try). Crossrail has put an even stronger emphasis on design.
Yeah it may be an overgeneralization, but from a recent trip nothing about the stations I visited particularly sticks out in my memory beyond concrete and plain tile.
Today it's a very important bike route for people living south of the river Elbe (especially in the districts Wilhelmsburg and Veddel, both experienced heavy gentrification in the last two decades).
While the english version only states yearly usage numbers for 2008 (300k cars, 63k bikes, 700k pedestrians) the german also has numbers for 2018 (52k cars, 300k bikes, > 1 million pedestrians).
