Sabotage - OR, not evidence

The assertion that immersed tubes are more susceptible to sabotage or terrorist attack has been in the article, without citation, since 18 September 2005. It's had a citation-needed template on it since 20 September 2008, more than two years ago. That's five years too long for such a tall claim to go so entirely unevidenced; it sure seems like someone's supposition. It may well be true, and I'm not saying that it's not, but for such a claim to stand we need real hard evidence, not original research, deduction, or supposition. We'd need to show that such a sabotage had actually happened, that the commissioners, designer, and builders of immersed tube systems had considered this eventuality, or that serious civil engineers had examined this and found that it was a credible threat. I'm going to remove it (and I feel guilty for not having done so in 2008) and it shouldn't be restored without adequate reliable sources. -- Finlay McWalter ☻ Talk 17:20, 18 October 2010 (UTC)[reply]

Corrosion / expected life

How is corrosion dealt with, how long do we expect such tubes to last ? Aesma (talk) 16:39, 13 September 2013 (UTC)[reply]

Removing examples

We don't need a list of everybody's favorite immersed tube. We don't need an invitation to expand the list either. There are far to many of them. We have categories for that. I'll make sure that the examples are in Category:Immersed tube tunnels (currently almost empty), with subcategories for countries that have more than one of them, and then remove the example list except for some very notable ones. PiusImpavidus (talk) 13:13, 22 January 2016 (UTC)[reply]

You're rehashing an old discussion regarding lists vs categories, and lists are allowable. I would suggest creating an article called List of immersed tube tunnels. --Jeremy (blah blah • I did it!) 16:09, 22 January 2016 (UTC)[reply]

Based on the size/length of the article, I would consider there to be room to keep the list here. However, if the list is returned, it should be done as a table where the reader can sort by year built or such Without sorting abilities, a bulleted list is no better than a category. - ¢Spender1983 (talk) 07:04, 23 January 2016 (UTC)[reply]

First immersed tunnel?

Was Michigan Central Railway Tunnel really the first immersed tunnel? Wasn't the Paris metro tunnel under the river Seine built earlier? The Seine metro tunnel was also built as a so called "sink tunnel". 212.100.101.104 (talk) 00:20, 21 March 2023 (UTC)[reply]
