In Downtown Los Angeles, a glass slide is being attached to California’s tallest building, almost 1,000 feet above the ground.

Dubbed Skyslide, the slide will descend from the 70th to the 69th floor of the 1,017-foot-tall US Bank Tower. The building was designed by Pei Cobb Freed & Partners and completed in 1989. According to the Council on Tall Buildings and Urban Habitat, it was the first supertall on the West Coast.

Constructed from 1.25-inch-thick glass panels, the Skyslide will be approximately 46 feet long and 4 feet wide and adhere to the building’s exterior via a metal support system.

Singapore-based developer OUE Limited is initiating the project as part of Skyspace L.A., an approximately 850-square-foot observation and exhibition space on top of the tower. The project is part of a $50 million building-wide renovation plan and upgrade led by Gensler.

Skyspace L.A. is primarily geared towards tourists, though no doubt locals will appreciate panoramic views of the city, San Gabriel Mountains, and the Pacific Ocean. It will cost $25 to visit Skyspace and a ride on the Skyslide will cost an additional $8 when the site opens on June 25th.

Although this slide may be the most vertigo-inducing, it’s not the first large-scale slide to be installed on a tall structure. The 376-foot-tall ArcelorMittal Orbit Tower in London’s Olympic Park, designed by Anish Kapoor, features the world’s longest and fastest tunnel slide. Riders descend for 40 seconds at 15 miles per hour, getting fantastic views of East London along the way.
