Abstract: Henry Petroski explains how a bridge's design becomes a special challenge when it shares scenery with an engineering icon. The US Highway 93 that crosses the Colorado River via the two-lane pavement atop the crest of the Hoover Dam has long been a key vehicular route between Phoenix and Las Vegas, and with the implementation of the North American Free Trade Agreement in the mid-1990s, trucks traveling between Canada and Mexico began to rely ever more heavily on it. The third route was known as the Sugarloaf Mountain Roadway Alignment, and it involved cutting through elevated rock to eliminate steep grades. The Hoover Dam Bypass Colorado River Bridge is joining one of the most famous civil engineering landmarks in the world, and pairing off in such close proximity that the visual presentations of each will forever be tied together as one.
