"Ten Remarkable U.S. Bridges\nCombining monumental design, feats of engineering, and\u2014often\u2014the natural beauty of the landscape, bridges are some of the country's most iconic landmarks. AD visits truly amazing examples from coast to coast\nNew River Gorge Bridge in Fayetteville, West Virginia\n\nCompleted in October 1977 and extending 3,030 feet across the New River Gorge, the imposing steel structure was at one point the longest single-span arch bridge in the world. It has become a symbol of West Virginia, so much so that each year, on the third Saturday in October, Fayette County celebrates Bridge Day by closing the span to vehicular traffic. In addition to offering rappelling and BASE-jumping demonstrations, the festival marks the only day pedestrians are allowed to walk across the bridge.\nSundial Bridge in Redding, California\n\nSpanish architect and engineer Santiago Calatrava designed this innovative 700-foot-long pedestrian link\u2014his first bridge in the U.S. Opened in July 2004, the cantilevered, cable-stayed 1,600-ton structure, whose shape mimics that of a large sundial, gracefully arcs across the Sacramento River in Redding's Turtle Bay Exploration Park. Calatrava's first vehicular bridge in the U.S., the Margaret Hunt Hill Bridge in Dallas, is slated to open later this year.\nSachs Bridge in Gettysburg, Pennsylvania\n\nConsidered one of the covered-bridge capitals of the world, Pennsylvania was once home to nearly 1,500 covered bridges. But only a fraction remain intact today, including the 160-year-old Sachs Bridge, which was used by both the Union and Confederate armies during the Civil War (most notably during the Battle of Gettysburg). It was designated the state's most historic bridge in 1938 and is listed on the National Register of Historic Places.\nBP Bridge in Chicago\n\nPritzker Prize\u2013winning architect Frank Gehry's first and only bridge opened in downtown Chicago's Millennium Park in July 2004. Named for the energy company BP, a major donor to the project, the stainless-steel footbridge\u2014bearing Gehry's signature biomorphic curves\u2014winds its way across Columbus Drive from Millennium Park to Daley Bicentennial Plaza.\nBixby Creek Bridge in Big Sur, California\n\nAs part of the legendary Highway 1 that stretches along the Pacific coast, the Bixby Creek Bridge is emblematic of one of the country's most scenic drives. When the bridge was completed in 1932, it was the highest single-arch span in the world (measuring 280 feet high and 714 feet long) and provided a welcome alternative to the long detour previously necessary to cross Bixby Canyon.\nBenson Bridge in Multnomah Falls, Oregon\n\nThe tallest waterfall in Oregon and one of the tallest in the U.S., Multnomah Falls drops more than 600 feet, in two stages. In 1914 prominent Oregon businessman Simon Benson financed the 45-foot-long stone pedestrian bridge that spans the pool between the 542-foot upper falls and the 69-foot lower falls so visitors could experience magnificent views of both. Benson later donated funds to create a trail that crosses the footbridge and continues to the top of the falls.\nMike O'Callaghan\u2013Pat Tillman Memorial Bridge near Boulder City, Nevada\n\nThe Hoover Dam, one of America's most iconic landmarks, now has an eye-catching companion less than a half-mile away. The soaring bridge, which opened in October 2010 and diverts regular traffic from the dam, spans 1,900 feet across the Colorado River and, at about 900 feet high, is the longest single-span concrete arch bridge in the world. The structure was named for two noteworthy individuals from the states it connects: Mike O'Callaghan, a former two-term governor of Nevada, and Pat Tillman, the Arizona Cardinals football player who died at age 27 while serving in Afghanistan.\nDrum Bridge at the Japanese Tea Garden in San Francisco\n\nThe Japanese Tea Garden, located beside the Herzog &amp;amp; de Meuron\u2013designed de Young Museum, is one of Golden Gate Park's prime attractions. The garden's authentic 19th-century bridge was built by Shinshichi Nakatani in Japan and shipped to San Francisco for the 1894 California Midwinter International Exposition. The bridge plays more of an aesthetic role than a practical one\u2014because of its dramatic, high arch, visitors must ascend ladderlike footholds to walk across it.\nLeonard P. Zakim Bunker Hill Memorial Bridge in Boston\n\nThe world's widest cable-stayed bridge became a symbol of freedom and unity for the city of Boston when it was completed in 2002. The span, which crosses the Charles River, honors civil rights activist Lenny Zakim as well as the American colonists who fought in the Battle of Bunker Hill during the Revolutionary War. (The Bunker Hill Monument can be seen from the bridge.) Built as part of the Big Dig, the country's most expensive highway construction project, it replaced the 1950s Charlestown High Bridge."^^<http://www.w3.org/2001/XMLSchema#string>
