A social history of London Bridges might have been a better title as Cross River Traffic is a social history book not an engineering tome. As such, there are fantastic stories associated with the bridges and other tales from the riverbank, and loads, in the version I have, about activities on the river. It is witty, modern and entertainingly written and the photos are clearly (in keeping with the rest of the book) an attempt to make the reader look at the bridges in a different fashion. As a general reader I found it easy to grasp the reasons why the bridges were built and, as a Londoner, intrigued as to how much they have shaped the city and delighted by the many humourous anecdotes attached to the crossings.
