According to the artist himself, he has engaged the site's knotty condition: "there are five roads leading to the plaza, with a highway overpass on top, and a subway line underneath. There are three different levels of infrastructure, creating a complex fabric that affects the pedestrian nature of the area. So, the question was, how do we add the pedestrian element so people will animate the five different streets". To accomplish this task, the artist enveloped the 105-foot-wide overpass in an ovular steel frame clad with aluminum. Measuring 348 feet long, 157 feet wide, and 82 feet tall, it cloaks cars speeding along the overpass (text from www.archrecord.com).
