The Elbe Tunnel 1

The history of the tunnel under the Elbe.

In the late 19th century on the right bank of the Elbe was situated cargo port of Hamburg, who did not cope with the huge volume of goods transported and had to be expanded, increasing the territory due Shtaynverder area, which was on the left bank. To dockers, and they at that time was about 20 thousand, to get to the other side, you had to walk about 12 kilometers to get to a single bridge. Or swim on ferries that with such a flow has long been not handle, and depended on the weather. During an ice drift small ferry simply not working. Hours of waiting on ferries and their frequent clashes with ships and dock workers led to a strike in 1986.
To solve this problem it was proposed many projects:

  • Build a new bridge, but as the Elbe were seagoing vessels, the height of it was to be 55 meters and the cost proved unaffordable;
  • It was proposed and swing bridge, but it would take up much space and because of the low rate of turn made it difficult to cross-sea vessels;
  • Device cable car and other projects are simply not even considered.

The choice fell on the tunnel

Tender, who conducted the Hamburg Senate in 1901 (if it could be said, at the time) won the tunnel project engineer Ludwig Vendemuta and supervised the construction of Otto Stockhausen, which began in 1907. Tunnel employed about 4,400 workers, engineers and technical workers.

The tunnel was a two pipes with a diameter of 6 meters laid at a depth of 24 meters, for travel in both directions and the length of 426.5 m each. Tunneling shield jacks moved, excavated soil was spilling out, and the walls of the tunnel and immediately reinforced concrete. To tunneling works were normal and in the tunnel does not leak water, it constantly pressurizing the air. Many workers became ill and three decompression sickness even died.

In 1911 the construction of the tunnel ended, and he was put into operation. The cost of the entire complex of buildings was 10.7 million gold marks, which at that time was enormous, but the cost-effectiveness was evident. After all, the bandwidth of the tunnel was about 14,000 people per hour.

And where is the installation of elevators?

The Elbe Tunnel 3

The main feature of the Hamburg tunnel - the lack of entries in the tunnel, that is, access roads. People, horse-drawn carriages and cars enter the tunnel to the elevator lifts, although provided for pedestrians and metal ladders. For the entrance to the tunnel used two passenger elevators and four car elevators. Elevator maintenance of the tunnel regularly conducted more than 90 years without replacement.

Only in the 2000s, during the reconstruction of the tunnel, load-bearing structures have been replaced by elevator shafts and elevators themselves. Now car lift installed capacity of 10 tons and can accommodate vehicles up to 9 m. The turbines on the ceiling provide a replacement and air circulation in the tunnel.

The tunnel is divided into the roadway with speed bumps and sidewalks on both sides of the road.

With the commissioning of a new tunnel, as the old works.

In the mid-70s put into operation a new 8-band road tunnel through the Elbe and the old moved to the engineering and historical plane.

The Elbe Tunnel 5

But ... today annually through the old tunnel Hamburg more than 220 million vehicles, 60 thousand cyclists and pedestrians more than 700 thousand. For vehicles up to 1.9 m wide tunnel works in the daytime on weekdays and travel costs 2.5 euros, and for cyclists and pedestrians - around the clock and free of charge.

On the 100th anniversary of the opening of the tunnel in September 2011, he was recognized as a historic symbol of engineering and the art of building in Germany, and earlier, in 2003, he is under state protection as a historical and cultural monument.
