The eight posts are anchored in pairs into four large concrete footings that are in turn anchored to the bedrock by ninety-six 2 + 1⁄ 2-inch-diameter (64 mm) high strength steel threaded rod rock anchors grouted 46 feet (14 m) deep into the rock.
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 mm × 810 mm) box posts having four posts on each side of the visitor's center, once completed. The Skywalk length extending out from the post supports closest to the canyon wall is 70 feet (21 m). The overall Skywalk width is 65 feet (20 m). With the help of architect Mark Ross Johnson, that idea evolved into a rectangular walkway and eventually the "U"-shaped walkway constructed. Design and construction Aerial view of the Grand Canyon Skywalkĭavid Jin, an entrepreneur who had been involved with tourism and the Hualapai Nation for some time, had the idea of extending a platform out over the edge of the Grand Canyon. The attraction's operators have reported over one million visitors per year several times, first occurring in 2015.
The nearest city with a population greater than 10,000 people is Kingman, Arizona, about 50 miles (80 km) south.Ĭommissioned and owned by the Hualapai Indian tribe, the skywalk was unveiled March 20, 2007, and opened to the general public on March 28, 2007. The attraction is immediately north of Grand Canyon West Airport and about 75 miles (121 km) east of Las Vegas, Nevada, although nearly 130 miles (210 km) by car. The vertical drop directly below the skywalk is 500 to 800 feet (150 to 240 m).
The elevation of the Colorado River at the base of the canyon below is 1,160 ft (350 m). USGS topographic maps indicate the Skywalk's elevation as 4,770 ft (1,450 m) above sea level. It opened as a tourist attraction in 2007, located outside the boundaries of the Grand Canyon National Park. The Grand Canyon Skywalk is a horseshoe-shaped cantilever bridge with a glass walkway at Eagle Point in Arizona near the Colorado River, on the edge of a side canyon in the Grand Canyon West area of the main canyon.
