Schöne Pläne für
die Docklands

In London soll eine neue Schwebefähre entstehen

Im Zuge des Ausbaus der Londoner Docklands ist im September 1998 eine Fußgängerbrücke  ("Royal Victoria Dock Footbridge") fertiggestellt worden. Der
Entwurf sieht einen zweiten Bauabschnitt vor, in dem der Brücke eine Gondel
hinzugefügt wird, so dass zum ersten Mal seit Jahrzehnten wieder eine Schwebefähre in Betrieb gehen würde. 

Der Docklands-Entwicklung ist eine französische Website gewidmet. Über die Schwebefähren-Pläne heißt es auf einer britischen Website: "The design for this bridge was chosen from a design competition in which seven teams submitted proposals.  The winning scheme, by engineers Techniker and architects Lifschutz Davidson, was for an elegant cable stay bridge with a span of 128 metres, swung between two 50 metre masts, at a height of 14 metres above the dock. At 200 metres this is the longest of the Docklands footbridges, and the brief for its design required the needs of sailors and water users to be taken into account as well as those of pedestrians. The bridge connects the Urban Village at West Silvertown with the proposed Exhibition Centre and with the stations at Custom House. The design allows for the future build out into the dock proposed for the Exhibition Centre, and also safeguards for the future addition of a transporter car to operate underneath the bridge, thus allowing passengers to be carried across in security and safety whilst also being protected from the elements. The viability of the transporter, however, is dependent on the full development of the surrounding dock estate." 

"A mini transporter bridge"

Bei asranet.com heißt es: "A mini transporter bridge design was architect Lifschutz Davidson�s response to a design brief from the then London Docklands Development Corporation for a landmark 130m span pedestrian crossing over a stretch of water which was being developed as a regional sailing centre. A 13m minimum clearance below the deck seemed to imply that pedestrians would need some form of weather protection � but at the same time the structure had to cause as little wind turbulence as possible. �Some form of tube would have been a possibility,� says Wells. �But who would want to cross it late on Saturday night?� The transporter bridge alternative would allow pedestrians to enjoy the views from the open top deck in fine weather, with the option of skimming across the dock in a 40 passenger enclosed car in less clement conditions.

An inverted Fink truss was the chosen structural form, partly because of its inherent lightness and flexibility, partly because it invoked both the dockyard cranes and the forest of masts and cables that once filled the dock. Five fabricated �whale backbone� steel box girders linking the six masts were spigoted together around the mast feet. This simple to erect pin-jointed arrangement also significantly increased the structure�s inherent lateral damping. Beneath this backbone runs the track for the passenger gondola, which weighs 11t fully loaded. Wells says the gondola only increases midspan deflection by a maximum of 75 mm. �Dynamically, there was no problem with the gondola swinging beneath the deck, as its �bouncing� frequency is very much lower than that of the bridge. And in high winds it will be able to winch itself close up under the deck during the crossing.� 

Architecture Week schreibt: "...The other main link to the center is the Lifschutz Davidson-designed high-level transporter bridge connecting ExCeL with the newly built residential areas on the south side of the river.  The bridge is modeled on the transporter bridges at Newport in Wales and Middlesborough in the north of  England. Lifts are provided to the upper pedestrian deck, which provides stunning views of ExCeL's graceful colonnade and Moxley's eye-catching system of external roof hangers."
