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. It opened as a tourist attraction in 2007, located outside the boundaries of the Grand Canyon National Park.

A cantilever is a rigid structural element that extends horizontally and is unsupported at one end. Typically it extends from a flat vertical surface such as a wall, to which it must be firmly attached. Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab.
