Roman bridges

The Romans were the first great builders of bridges in the Western World. Professor O'Connor, a civil engineer and expert in bridge construction, has personally examined a large number of those bridges that still remain often in daily use, throughout the Roman empire - an area extending from Hadrian's Wall in the north of England to Shustar in modern Iran.

In this book he presents a thorough listing and description of all known bridges, including some 330 stone arch bridges, 34 timber bridges and 94 aqueducts. In many cases the construction of the bridges is illustrated by the author's own photographs and sketches.

.

Introductory chapters place the bridges in their geographical and historical contexts, with detailed maps of the empire-wide system of Roman roads and discussion of how these came to be constructed, and an investigation of the technology available to the Romans.

An important element of Professor O'Connor's purpose is to elucidate the principles used by the Romans in designing their bridges, and in his concluding chapters he examines the proportions of the stone arches and subjects the rules that emerge to modern structural analysis. This handsome book will be of value to archaeologists and engineers and to all those interested in the history of technology.
