History: Construction Of Tower Bridge, 1886-1894, London, England, United Kingdom

Some of the control mechanism for the signalling equipment has been preserved and may be seen working in the bridge's museum.
Reaction
Although the bridge is an undoubted landmark, professional commentators in the early 20th century were critical of its aesthetics. "It represents the vice of tawdriness and pretentiousness, and of falsification of the actual facts of the structure", wrote H. H. Statham, while Frank Brangwyn stated that "A more absurd structure than the Tower Bridge was never thrown across a strategic river".
