"No one person can be a historian and an archaeologist, an engineer and a zoologist and a master of all the other subjects that the River reveals, but you have to understand something of them all and be able to interpret their mysteries for the reader. John Duffy not only succeeds in doing this, his talent as an artist means he can do it in pictures as well." - Dick Warner. 

This book documents the River Barrow's 45 bridge crossings and provides much information on structures that are taken for granted today.
