From the monumental splendour of Tower Bridge and the august span at Westminster to the engineering masterpieces at Ironbridge and the Forth, bridges comprise some of the most recognisable landmarks in Britain. Whether the smallest arch or the largest overpass, each has a rich architectural, economic, social and sometimes even religious history. This beautifully illustrated introduction by Richard Hayman explains how piety built and maintained bridges in the Middle Ages; how economic forces inspired a new generation of road bridges in the eighteenth century, such as the Menai Bridge in North Wales, and how technological prowess gave us soaring Victorian railway viaducts and the concrete road bridges of the twentieth century.
