                        Bridges are remarkable structures. Often vast, immense, and sometimes beautiful, they can be icons of cities. David Blockley explains how to read a bridge, how they stand up, and how engineers design them to be so strong. He examines the engineering problems posed by bridges, and considers their cultural, aesthetic, and historical importance.
