Who in 1911 opened St. Pauli Elbe Tunnel - as opposed to the new Elbe and age Elbtunnel called - is 426.5 meters long and connects with its two tubes, the inner city of Hamburg at the St. Pauli landing bridges with stone Werder and his shipyard and industrial plants.
It crosses the North Elbe and is still used as a public highway. In his opening, he was considered a technical sensation since 2003 and is a listed building. In 2007 he was nominated for the "Historical landmark of civil engineering in Germany."
In 1907 began building his air was used to prevent excess pressure generated by the so-water intrusion. The beginning and the end nearest vertical excavations were carried out with the help of an iron caisson. The two horizontal tunnels were built in shield tunneling process and lead to a sole depth of 24 meters from the St. Pauli landing bridges to Steinwerder on the south bank of the North Elbe. The upper edge of the six-meter tubes ("for a coach with raised sticks") is situated twelve meters below the mean high water. Between tunnel and river bed lay a three meter thick layer of silt.
Of a total of approximately 4,400 workers who were involved in this project were three workers died as a result of excess pressure in the building, through the bends were killed and two more in accidents. 689 more workers survived the bends. The total cost of Elbunterführung were at 10.7 million gold marks.
History of the tunnel:
- 1901: Decision to build - Start of planning
- 1907: Start of construction
- 1911: opening of the tunnel
- 1951: Expansion of the old DC in favor of fluorescent lighting.
- 1956: installation of ventilation systems in order to keep from increasing motor vehicle traffic increased carbon monoxide levels in check.
- 1959: Installation of three escalators for the rise in pedestrian traffic.
- 1982-1983: full closure of the tunnel for the construction of a 210 m long reinforced concrete slab on the Labský důl to secure the tunnels as part of the channel deepening.
- Since 1995: A comprehensive program for basic repairs with the aim of restoring the original appearance of 1911, while the technical facilities of the state of technology. The work will be completed in 2010, so that the St. Pauli Elbe Tunnel will appear on his 100th anniversary of its former glory.
- 2003: The St. Pauli Elbe Tunnel is placed under monument protection.
The tunnel
This panorama was taken in the eastern of the two tunnels. It was about midway between the two approaches. The preview shows a spherical projection of the spherical panoramas. This creates the impression of two tunnels to be seen.
