(WorldKings - Values 2017) Top 100 Great Works in World History - P.82. Grand Canyon Skywalk

22-10-2017

(WorldKings.org) The Grand Canyon Skywalk is a horseshoe-shaped cantilever bridge with a glass walkway in Arizona near the Colorado River on the edge of a side canyon in the Grand Canyon West area of the main canyon.

 

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 mm × 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 2 1⁄2-inch-diameter (64 mm) DYWIDAG (acronym pronounced Doo-Wee-Dag) high strength steel threaded rod rock anchors grouted 46 feet (14 m) deep into the rock.

 

 

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. The Skywalk is east of Meadview and north of Peach Springs with Kingman being the closest city of some size.

 

 

There are several packages available for purchase at the airport terminal visitor center. Every package includes parking at the terminal and shuttle bus transportation to the two scenic viewing areas, and the Hualapai Ranch. As of 2015, the final 9 miles (14 km) of county-maintained road to the attraction has been paved  and is now accessible to everyone. In addition to admission, visitors may purchase professional photographs of their visit to the Skywalk in the gift shop, as personal cameras are not allowed on the Skywalk itself. Along with other personal property, they must be stored in a locker before entering the Skywalk.
