Commissioned and owned by the Hualapai Indian tribe, it was unveiled March 20, 2007, and opened to the general public on March 28, 2007. It is accessed via the Grand Canyon West Airport terminal or a 120-mile (190 km) drive from Las Vegas, which includes a 10-mile (16 km) stretch of dirt road which is currently under development. The Skywalk is east of Meadview and north of Peach Springs with Kingman being the closest major city.
The overall Skywalk width is 65 feet (20 m). The Skywalk length extending out from the post supports closest to the canyon wall is 70 feet (21 m). The outer and inner 32-inch-wide (810 mm) by 72-inch-deep (1,800 mm) bridge box beams are supported by eight 32-by-32-inch (810 × 810 mm) box posts having four posts on each side of the visitor’s center, once completed. The eight posts are anchored in pairs into four large concrete footings that are in turn anchored to the bedrock by ninety-six 21⁄2-inch-diameter (64 mm) DYWIDAG high strength steel threaded rod rock anchors grouted 46 feet (14 m) deep into the rock. The deck of the Skywalk has been made with four layers of Saint-Gobain Diamant low iron glass with DuPont SentryGlas interlayer. Deck width is 10 feet 2 inches (3.10 m). The Skywalk glass railings were made with the same glass as the deck, but fewer layers (two) bent to follow the walkway’s curvature. The glass railings are 5 feet 2 inches (1.57 m) tall and have been designed for high wind pressures.
