The Riverwalk is located in the middle of downtown Chicago and extends nearly 2,800 ft. along the main branch of the Chicago River between State Street and Lake Street. The project consists of six themed "rooms" connected by canopied "underbridges" beneath the existing bascule bridges to provide a continuous path. The goal of the project was to provide an area for Chicago's residents, workers, and visitors to connect with nature in the heart of the city, which led to a wide-ranging theme of sustainability throughout all aspects of the design. This paper presents a case study of the considerations and challenges associated with the design and construction of a sustainable public project in a complex urban environment.
