But as she shows in her book "Skyscrapers," there is an intertwining of form and function, and where man built up in buildings, he builds out via bridges. The book's design even emphasizes - where Skyscrapers was an extremely tall and thin book, Bridges goes for width, to try and bring the spans into the range of the printed page. Yet so often, the task is not possible, and even on the wide pages the bridge disappears into the distance.
The book looks at the engineering involved, but does not dwell on it. Rather it celebrates how the improvement of engineering practices have been able to move man forward. A veritable love poem to something that we often take too much for granted.
