Guided Story

You're looking at the remarkable cutterhead T.R.U.D.E., a technical monument commemorating the massive engineering feat of constructing the fourth Elbe tunnel tube. Between 1997 and 2000, this behemoth worked beneath the riverbed. With a diameter of 14.20 meters, T.R.U.D.E. was the largest tunnel boring machine of its time. It moved over 400,000 cubic meters of sand, gravel, and stones, weighing in at over 2000 tons. If you turn around, you'll spot nearby landmarks like the MW 12 Emil road roller and the Museum of Work, both echoing Hamburg's rich industrial heritage.
