Old Elbe Tunnel or St. Pauli Elbe Tunnel which opened in 1911, is a pedestrian and vehicle tunnel in Hamburg, Germany. The 426 m long tunnel was a technical sensation; 24 m beneath the surface, two 6 m diameter tubes connect central Hamburg with the docks and shipyards on the south side of the river Elbe. This was a big improvement for tens of thousands of workers in one of the busiest harbors in the world. Four large lifts on either side of the tunnel carry pedestrians and vehicles to the bottom. The two tunnels are both still in operation, though due to their limited capacity by today's standards, other bridges and tunnels have been built and taken over most of the traffic. In 2008 approximately 300,000 cars, 63,000 bicycles, and 700,000 pedestrians used the tunnel. The tunnel is opened 24 hours for pedestrians and bicycles. For motorized vehicles, opening times are currently Monday to Friday from 5:20 AM to 8:00 PM and on Saturdays from 5:20 AM to 4:00 PM.
History
On 22 July 1907 the construction, undertaken by Philipp Holzmann, started to connect the quarters of St. Pauli near the Landungsbrücken and Steinwerder. Work was done under pressure because the tunnel was below the water table of the Elbe. This type of building technique was used in the 19th century, in large engineering excavations, such as with the piers of bridges and with tunnels, where caissons under pressure were used to keep water from flooding the excavations, such as the foundations of the Brooklyn Bridge in New York City. Workers who spend time in high-pressure atmospheric pressure conditions are at risk when they return to the lower pressure outside the caisson without slowly reducing the surrounding pressure. Due to the problems associated with decompression sickness, many of the men working on the Elbe tunnel were affected by what was known at the time as "Caissons Disease". Of 4,400 workers three men died, 74 suffered severe cases and more than 600 came down with light symptoms. The tunnel opened on 7 September 1911.
Modern usage
In the tunnel an art exhibition and a long-distance running event Elbtunnel-Marathon take place. In 2008 the tunnel participated in the Tag des offenen Denkmals, a Germany-wide annual event sponsored by the Deutsche Stiftung Denkmalschutz that opens cultural heritage sites to the public.
Media
The old tunnel has featured in several films including The Odessa File, Matchless, $, The American Friend and Secret Agent Fireball. The tunnel was also featured in the music video for "One " by German band Scooter.
Decoration
The tunnel walls are decorated with glazed terra cotta ornaments displaying items related to the Elbe river. While most fish or crabs, a few show different items like litter and rats, too.
