The River Thames, dividing London into two clearly defined halves, is one of the major themes in the latest instalment of this popular series. This 132-page special publication looks at the bus routes that link north and south London on the ten bridges closest to the heart of the capital from Battersea Bridge downstream to the magnificent Tower Bridge. The publication also considers what might have been had London's electric trolleybus network - the world's largest, which closed 60 years ago - been extended deep into south London with cross-river crossings.
