Comment[edit]

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

Comparisons[edit]

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)[reply]

Types of tunnels[edit]

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)[reply]

Table of data[edit]

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)[reply]

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)[reply]

Downward slope has less carbon footprint?[edit]

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.
