Masonry arch bridges have proved to be reliable, enduring structures and remain a vital part of the road, rail and waterway infrastructure in the UK and other countries; but they are facing a number of challenges associated with their extended period in service and the changing requirements of modern transport systems.

In order to ensure the continued efficient use of these assets in the future it is necessary to manage and maintain them carefully, with due regard to, and an adequate understanding of, their special characteristics and needs. In a number of important ways these are distinct from those of more modern structures and the effective stewardship of masonry arch bridges requires some specialist knowledge and a particular approach.

This report provides information and guidance which will assist those responsible for this task in achieving their aims.
