It will be fine until a Russian sub crashes into it.

Hong Kong builds all its harbour tunnels with this type of tube, however, when they sink them into place they sit on the sea bed.

My thinking was heading that way. 100ft down is OK for surface vessels but some loon sub driver above and below and all hell could break loose :worried:

On the plus side Mick, by 2050 Dapol might of released their WC/BoB...........then again that would of been over 40years in the making, let's hope they won't of been forced to rush it!!!!

4000ft deep though, can't they build a faster ferry?? 21hrs driving isn't that bad, they could always fly.

Presumably these must be massive towns that are migrated between, I mean whose got a government stupid enough to waste 30billion on a project that will definitely cost double definitely be 6 years late and never live up to the numbers they claimed would use it ????????

Be better with trains in it.

That little cartoon at the end of your post was really clever Mick it had me in stitches and like you I doubt if I will ever go through those tubes .
I would love to go through the channel tunnel one day just for the sake of saying I have done it .

Iíd definitely use it, why not? The failure of any tunnel wall is unlikely to be great, so just because thatís floating rather than buried, meh!

If itís on time Iíll be 64, so itís a possibility. No doubt Iíll still be some way off retirement by the time I get there!

it will be interesting to see how they are going to cope with tides going up and down and Storms.

Anyone who's used the Conwy Bypass on the A55, second Tyne Tunnel or the Medway Tunnel has already gone through an immersed tube tunnel. The only real difference with this planned one is that it's suspended from pontoons instead of sitting in a trench dug out of the river bottom - the latter being a tad impractical when the bottom's 4000' down.

it will be interesting to see how they are going to cope with tides going up and down and Storms.

Good point - I suspect that the tides would be catered for by having the tubes exit above the water rather than cutting straight into the fjord banks, then connected to the land-based section by some form of hinged linkspan.

If the suspension pontoons are large enough I doubt that storms would be too much of an issue. Looking at the map, the location appears to be some way inland so should be pretty sheltered.
