Omschrijving

The third edition of The Portland Bridge Book is like an old faithful bridge that's been restored by a dedicated crew of specialists to increase its carrying capacity for the public's enjoyment. Over a span of 225 pages (50 percent larger than the second edition and more than twice the size of the first edition), this edition delivers:

150 historic and large format contemporary photographs, many published for the first time Annotated drawings by Joseph Boquiren showing Portland's movable bridges in operation How & Why Bridges Are Built, written by Fremont Bridge field engineer Ed Wortman Expanded and localized glossary of bridge terms Portland transportation history timeline, truss patterns, bridge poetry, lyrics New chapter about the Sauvie Island Bridge, the first new river bridge built by Multnomah County in 50 years

This vital Portland connection now profiles 15 highway bridges and four railroad bridges across the Willamette and Columbia rivers in the metro area. Each structure's general history, technical details, source of its name, and more are explained in accessible language.

About the Authors and Lead Photographer:

The two, partners-in-bridges since 1993, live in Portland. James Norman, an award-winning photographer, historian, and author of many books, lives in Salem, Oregon.
