A look at the old tunnel below the Elbe River in Hamburg, opened 7 May 1911 (a miracle of engineering at that time), still in operation today (for pedestrians as well as cars - the latter using elevators!)
length: 426.5m
depth: 24m under street level / 12 m under high tide level / 1m under riverbed

Nice photos, and there's an amazing Quicktime panorama near the bottom of the page. Plus a video for Real Player.
(The new 3-tube, 6-lane motorway Elbe tunnel was opened 1975, a 4th tube with two additional lanes added in 2002 due to the permanent and notorious traffic congestion. An airphoto showing the alignments of the two tunnels is here (http://de.wikipedia.org/wiki/Elbtunnel) on Wikipedia, looking southeast, with the new one in the foreground, the old one behind).
On the same site there is also a lot of fascinating stuff about (and the following is only the links on the main page.....) old powerplants, a small lignite mine lost to history, a bunker of the East German secret police, WW II radar technology, and massive structures in Hamburg housing anti-aircraft (flak) batteries during the war.
1 (http://www.lostplaces.de/flakhamburg/index.html) - 2 (http://www.lostplaces.de/wilhelmsburg/index.html ) Again, don't miss the Quicktime panoramas at the bottom of the second page (marked QTVR).....! (This second tower pictured has a 57x57 m base, is 41.6 m high, with 2 m thick walls and a ceiling strength of 3.5 m, consuming a total of 80,000 cu.m of reinforced concrete. It was dynamited by the Brits in 1947, but only the interior structures were destroyed.)
If you can read German, this site is well researched and presented - otherwise just have a look at the pics, they are great as well!
