How a structure and its creation are documented greatly impacts how it is remembered in history. Construction of the bridge downstream from Hoover Dam is unique both for its historical importance, by its proximity to the dam, and for its technical achievement, bridging the Black Canyon over the Colorado River with the longest concrete arch span in North America. The bridge challenges us to examine the juncture of nature and technology on a scale that is both grand and human.

When I first photographed the bridge in March 2009, it immediately captured my imagination. Watching the bridge's construction, especially at night, was both inspiring and captivating. The photo essay, which developed over two years from this initial encounter, allowed me to meld photographic and aesthetic sensibilities with a reawakened sense of childhood curiosity and awe. Photographically, the bridge as subject was creatively and technically challenging, dynamic and transitory.
