Book review: Tower Bridge: Operations Manual (1894 to date)

Richard Lankshear explores ways in which structural engineers are uniquely equipped to help tackle the UK's housing shortage.

This month's letters consider the restoration of Notre-Dame cathedral, the rising cost of insurance cover for engineers, subsidence terminology in insurance reports, lateral stability and other topics.

Nick von Behr enjoys this well-illustrated new history of Tower Bridge, covering its construction and life in operation, which will appeal to a broad general audience.
