The story seems to imply that it's the Dartford road tunnels that are
more at risk, but nontheless an "extreme tidal even" could flood the
CTRL tunnels at Dartford. Bluewater could also live up to it's name.

I particularly like the revelation that the CTRL Thames tunnel is
"low-lying". Consultants are sure on the ball these days.

Ho ho!

The CTRL planners have probably prepared for the possibility, though
nontheless it probably doesn't do anyone any harm to give those
concerned a gentle kick on the posterior to remind them of the risks.

in my OP an "extreme tidal even" should of course read an ""extreme
tidal event". If the tide remains extremely even then there's nothing
to worry about!
