Talk:Underwater tunnel

Comment
I have greatly improved this page (IMO) from the few lines it was. (Frediculous biggs 15:51, 10 October 2007 (UTC))

Comparisons
Each comparison also applies to other than undersea tunnels, so why not just let the general tunnel article, which is also better organised, do it all? Jim.henderson (talk) 22:31, 14 September 2010 (UTC)

Types of tunnels
Immersed tube and Submerged floating tunnel), different kinds of underwater tunnels, should be mentioned here. 184.166.6.102 (talk) 05:31, 5 May 2013 (UTC)

Table of data
I suggest we make the list into a sortable table, showing parameters such as length, depth, underwater length, price, road/rail/both, flag and such. See List of offshore wind farms for an example. TGCP (talk) 17:13, 13 October 2013 (UTC)

what irks me on a regular basis is the completely broken numeric ordering. Not only in this article. Ordering by length and 9km is longer than 111km. how can this be fixed? ZwergAlw (talk) 16:56, 19 November 2018 (UTC)

Downward slope has less carbon footprint?
This seems like a nonsensical argument- how is a downward slope producing less carbon than an upward slope for a bridge? What matters is the relative change in vehicle height- not whether they go down then up vs. up then down. This should be removed I think- it's not an actual benefit.
