McCulloch, the purchaser of the old London Bridge that was later shipped to Lake Havasu City in Arizona, believed that he was in fact buying Tower Bridge. [20] In 1974, the original operating mechanism was largely replaced by a new electro-hydraulic drive system, designed by BHA Cromwell House, with the original final pinions driven by modern hydraulic motors. [5], Construction started in 1886 and took eight years with five major contractors – Sir John Jackson (foundations), Baron Armstrong (hydraulics), William Webster, Sir H.H. [27] The bridge is on the London Inner Ring Road, and is on the eastern boundary of the London congestion charge zone (drivers do not incur the charge by crossing the bridge). Tower Bridge is a combined bascule and suspension bridge in London, built between 1886 and 1894. Die damit abrufbare Leistung wurde so effizient in mechanische Arbeit umgesetzt, dass die Fahrbahnen in zwei Minuten hochgeklappt werden konnten – eine technische Meisterleistung des ausgehenden 19.

[2], A Special Bridge or Subway Committee was formed in 1877, chaired by Sir Albert Joseph Altman, to find a solution. It specified the opening span must give a clear width of 200 feet (61 m) and a headroom of 135 feet (41 m). Diese diente, nach einer kurzen Betriebsphase als U-Bahn-Röhre, dann aber lediglich als Tunnel für Fußgänger. The two side-spans were suspension bridges, with rods anchored both at the abutments and through rods contained in the bridge's upper walkways. A spokesman for Tower Bridge is quoted as saying: "We tried to contact the American Embassy, but they wouldn't answer the phone. The latter still house the original steam engines and some of the original hydraulic machinery. [5], Two massive piers, containing over 70,000 long tons (78,400 short tons; 71,123 t) of concrete, were sunk into the riverbed to support the construction. In the towers and walkways is an exhibition on the history of the bridge. [10], Jones died in 1887 and George D. Stevenson took over the project. Die oberen Stege für die Fußgängerverbindung sind unbeweglich. [3], Ein teilweiser Nachbau der Tower Bridge steht in Suzhou (Jiangsu), China. [27], In April 2008 it was announced that the bridge would undergo a "facelift" costing £4 million, and taking four years to complete. [61] The Suzhou replica was renovated in 2019, giving it a new look that differs from the original London design.

Juni 1886; fünf Bauunternehmen und 432 Arbeiter waren mit dem Bau der Brücke beschäftigt. Die offizielle Eröffnung fand am 30. [3] More than fifty designs were submitted, including one from civil engineer Sir Joseph Bazalgette, which was rejected because of a lack of sufficient headroom. Die Türme wurden mit Portland-Kalkstein verkleidet, um einerseits den darunter liegenden Stahl zu schützen und andererseits der Brücke ein gefälligeres Aussehen zu verleihen. Die Prüfung der Vorschläge zog sich über Jahre hin, und erst 1884 wurde der Vorschlag von Horace Jones, dem Stadtbaumeister der City of London (der selbst der Jury angehörte), genehmigt.

The bus was near the edge of the south bascule when it started to rise; driver Albert Gunter made a split-second decision to accelerate, clearing a 3-foot (0.91 m) gap to drop 6 feet (1.8 m) onto the north bascule, which had not yet started to rise. Um die Integrität des historischen Bauwerks zu bewahren, hat die City of London Corporation eine Geschwindigkeitsbegrenzung von 20 mph (32 km/h) verhängt, die mit Kameras überwacht wird. In Ausnahmefällen wird die Brücke auch für kleinere Schiffe voll geöffnet: Dies geschieht aus zeremoniellen Gründen und gilt als ganz besondere Ehre. [37], The bridge is 800 feet (240 m) in length with two towers each 213 feet (65 m) high, built on piers. Daytime control was provided by red semaphore signals, mounted on small control cabins on either end of both bridge piers. Within the walkways a versatile new lighting system has been installed, designed by Eleni Shiarlis, for when the walkways are in use for exhibitions or functions. Entrance is from the west side of the bridge deck to the northern tower, from where visitors ascend to level 4 by lift before crossing the high-level walkways to the southern tower. Für die Türme und die Fußgängerbrücken waren über 11.000 Tonnen Stahl notwendig. The new system provides for both feature and atmospheric lighting, the latter using bespoke RGB LED luminaires, designed to be concealed within the bridge superstructure and fixed without the need for drilling (these requirements as a result of the bridge's Grade I status).

[2][4] Sir John Wolfe Barry was appointed engineer and Sir Horace Jones the architect (who was also one of the judges). [43][page needed][44] Water at a pressure of 750 psi (5.2 MPa), was pumped into the accumulators by a pair of stationary steam engines.

Tower Bridge is one of five London bridges owned and maintained by the Bridge House Estates, a charitable trust overseen by the City of London Corporation. am 3. 1894 wurde die Brücke für die Öffentlichkeit zugänglich gemacht. [39] The bascules, weighing over 1,000 tons each, are counterbalanced to minimise the force required and allow raising in five minutes. The pedestrian walkways are 143 feet (44 m) above the river at high tide, and accessed by lifts. Jubiläum der Gründung, die Leistungsfähigkeit der Royal Air Force unter Beweis stellen und gleichzeitig gegen die Regierung unter Premierminister Harold Wilson protestieren.
