A fully accessible looped walkway rises 16 feet above ground level above the substation and provides views of Seattle’s skyline, the landscaped terrace and a public park below. Various sound, light and kinetic art installations line the walkway and provide useful information about sustainable energy to the public. The glass envelope emits a warm glow at night, with the lights helping people navigate the walkway. A permanent exhibition space with interactivevisits on the history and future of energy innovation is located on the street level of Denny Substation. It is meant to function as a meeting space where people can exchange ideas and enjoy views of the bustling Denny Way traffic.
