Grand Canyon Skywalk
Grand Canyon West: Airport at left center. Grand Canyon National Park, north of the Colorado River.
Grand Canyon Skywalk is a transparent horseshoe-shaped cantilever amd a tourist attraction in Arizona near the Colorado River on the edge of a side canyon in the Grand Canyon West area of the main canyon.
Grand Canyon West Airport terminal or a 190 km drive from Las Vegas, which includes a 16 km stretch of dirt road which is currently under development.
The Skywalk is east of Meadview, Arizona and north of Peach Springs, Kingman, Arizona being the closest city of some size.
The Skywalk deck was designed for a 100-pound-per-square-foot live load along with code required seismic and wind forces.
The foundation can support the equivalent of 71 loaded Boeing 747 aircraft or an 8.0 magnitude earthquake within 50 miles (80 km).
Fine-tuning of the project occurred after a wind loading and pedestrian induced vibration analysis. Two tuned mass dampers were installed inside the outer box beam as well as one inside the inner box beam at the furthest extension of the Skywalk to reduce pedestrian footfall vibration.
The walkway could carry 822 people that weigh 200 pounds (91 kg) each without overstress, but maximum occupancy at one time is 120 people.
