Running under the river Elbe in Hamburg is a beautiful tunnel like no other. This 1/2 kilometre ‘technical marvel’, known as the ‘old river elbe tunnel’, was built in 1911, sits 24 metres below the river and connects central hamburg with the shipyard island of steinwerder. What makes the tunnel unique are the entry points on each side of the river: rather than just driving straight into the tunnel, vehicles enter a freight elevator which slowly descends to the tunnel below, the tunnel then taking traffic to a similar elevator on the opposite side which lifts them back to ground level.
