Tower Bridge, a Grade I listed structure in London, was constructed from 1886 to 1894 and incorporates bascule, suspension, and (until 1960) cantilever bridge types.[1] This bridge, situated near the Tower of London, spans the River Thames and is among five London bridges whose ownership and maintenance fall to the City Bridge Foundation.[1] Measuring 940 feet from abutment to abutment, the bridge features two towers each 213 feet tall, linked at their tops by two walkways, plus a central opening bascule pair for ship passage.[2]

Geography and history

Construction started on 22 April 1886, with the foundation stone laid by the Prince of Wales on 21 June, and took eight years.[3] Constructing a conventional fixed bridge at ground level was impossible, as it would block sailing vessels from reaching the Pool of London's port facilities.[4] Eight separate contracts governed the work, with the combined accepted tender sum reaching £830,005.[5] The construction site employed an average of 432 workers, though at least 1,200 individuals were involved in the overall building effort.[6]

What the cited sources add

The BBC News account of the 1952 bus incident states that driver Albert Gunter was given a £10 reward from London Transport after crossing the Tower Bridge gap.[8] The BBC News account reports that the Corporation of London accepted responsibility for the accident, stating "it appeared that the accident was attributable to an error of judgment on the part of the responsible employee at the bridge"[8] The Tower Bridge Restoration website notes that all four suspension chains were repainted using a state-of-the-art high-performance coating system, which will protect Tower Bridge for at least 25 years.[9] The towerbridge.org.uk account explains that during the competition to build Tower Bridge held between 1876 and 1879, fifty different designs were proposed, including many types of moving bridges.[10]

The Tower Bridge Restoration website reports that more than 22,000 litres of paint will eventually be used as the bridge is being repainted in its white and blue colour scheme.[11] The Classic FM account reports that composer Samuel Bordoli created a Live Music Sculpture for which 30 musicians from the Royal Academy of Music will perform along the entire West Walkway.[12]
