In December 1999, the city of London completed the first extension of its underground transportation system in more than 30 years. With its innovative engineering and striking design, the state-of-the-art Jubilee Line Extension has won recognition as one of the great engineering and architectural achievements of its age. A dynamic case study of the impact of new urban transportation, this illustrated book not only looks at the engineering and architectural challenges involved, but also examines the line extension's vital importance as a catalyst for urban regeneration. Engineers, architects, and city planners will find lessons here for all cities—at a time when urban renewal is a subject of intense interest throughout the world.
