The Grand Canyon Skywalk is a tourist attraction along the Colorado River on the edge of the Grand Canyon (Grand Canyon West) in the U.S. state of Arizona, commissioned by the Hualapai Indian tribe, opened to the public on March 28, 2007. The Skywalk will be charging $25 per person in addition to other entry fees.
The glass bridge is suspended 4,000 feet (1 219 meters) above the canyon. The bridge’s walls and floor are built of glass 4 inches (10.2 cm) thick. The horseshoe shaped bridge protrudes 65 (20 meters) feet from the edge of the canyon. The Skywalk is able to hold 70 tons of weight, allowing for 800 people weighing 175 lbs (80 kg) each to stand on the bridge. The allowed capacity, though, will be limited to only 120 persons. All visitors will be provided with shoe covers to protect them from slipping and to prevent scratching of the glass floor.
