Bridges is more than a picture book, however. Dupr� presents a chronological collection of more than 45 bridges, from early Roman aqueducts to the most recent accomplishments of this century. Each bridge is accompanied by text that, together with the photos, provides the reader with informative background, anecdotes, and cultural and historical context. For fact seekers, the relevant names and numbers are readily accessible. For the parents of inquisitive children, "cantilever" will roll from the tongue as easily as "tension" and "torsion."

Dupr� quietly proclaims in her introduction, "The unassuming poetry of bridges reveals itself to those who would see them." The author manages to convey this very poetry by giving us the tools to understand the power and grace of the bridge.
