For 2,000 years the most durable spanning structures have been built of masonry, and the surviving bridges of the Roman Empire have challenged master masons, architects and engineers to emulate and surpass them. Down the centuries, bridge-builders have been commissioned by monarchs, bishops, councils of state, cities, private individuals and, more recently, waterway and railway companies. The studies collected in this volume focus chiefly on the bridges, viaducts and aqueducts themselves and the actions of the designers and builders, but also encompass the political, economic and social contexts and outcomes of their creation. Famous bridges in Britain, Italy, France, Iran and the USA are all featured. Narratives of conception, design and construction predominate, but there are also papers on construction techniques, on the analysis of documentary sources, and on the continuing search by modern engineers for satisfactory scientific description of the strength and stability of arch bridges.

The construction of bridges in Britain and Ireland during the period of 1735 1835 was marked by important technical developments and the introduction of new materials. This book is a comprehensive history of bridge building during the century, treating the administration and financing of projects as well as the designs and methods of construction. All the bridges described are of interest as engineering works; as architecture some are unimportant but many achieved real grandeur and beauty. The book is based on exhaustive study of primary sources which are fully documented, but it is a highly readable account. More than half of it consists of narratives of individual bridge projects, in which all the men involved, from noblemen and generals to country masons and carpenters, come alive for the reader. Much of the detail of these stories has never been published before. Among the topics which can be traced through the narratives are the growth in spans and changes in the proportions of bridges, the borrowing and modification of Continental styles, a halting progress towards the use of scientific theory in bridge design, the introduction of iron arches and the important role played by 'amateurs', including Tom Paine and Samuel Johnson. Over 200 illustrations accompany the text.

Travels in the Colonies in 1773-1775 Described in the Letters of William Mylne contains a narrative of the two years that Scottish architect and engineer William Mylne spent in the American colonies. The letters included in this volume, written from Mylne's own pen to his sister Anne and brother Robert, document Mylne's journeys from his home in Edinburg to the American colonies in South Carolina, Georgia, Charlestown, and New York.
