Is there some particular reason this is called the Tokyo Wan Aqua-Line, instead of more obvious "Tokyo Bay Aqua-Line"? Jpatokal 10:50, 16 Jul 2004 (UTC)

Because if you read a Japanese map it says "Toukyou wan a-ku-a ra-i-n". 'Tokyo' and 'wan' are written in kanji (Japanese characters) and 'a-ku-a ra-i-n' are in katakana (used for foreign words). So "Tokyo Wan Aqua Line" is almost exactly what the locals call it. —The preceding unsigned comment was added by 220.147.135.176 ( talk • contribs) .

Just curious. Also, it'll help flesh out the article and the " Bridge-tunnel" article, which lists reasons for all B-T designs except this one. Does anyone know what was the thought process behind selecting a bridge-tunnel design over a high-level bridge or other design? Was it earthquake or other disaster considerations? Cost concerns? Infrastructure problems? The length of the crossing? Aesthetics?— WhosAsking ( talk) 14:18, 14 August 2008 (UTC) reply

The article says

The Tokyo Bay Aqua-Line reduced the drive between Chiba and Kanagawa, two important industrial regions, to 15 minutes

Okay, that's great, but how much of a reduction is this? Could someone add how long it took to drive from the opposite points before the Aqua-Line was built? Un sch ool 09:04, 2 November 2009 (UTC) reply
