Sasaki:芝加哥河主干有着悠久且丰富的历史，它在很多方面呈现了芝加哥城市本身的发展。芝加哥河以前是一条蜿蜒的沼泽，后来被硬化改造为工程河道以支持城市向工业型转换。为了改善卫生情况，城市将河流主干与南边分支水流方向倒转，在此之后，建筑师与城市设计师丹尼尔·伯纳姆提出了滨河步道与瓦克道高架桥的新愿景。近十年来，河流所扮演的角色随着芝加哥滨河项目再次转换——重拾芝加哥河的城市生态与休闲效益。

Sasaki:The Main Branch of the Chicago River has a long and storied history that in many ways mirrors the development of Chicago itself. Once a meandering marshy stream, the river first became an engineered channel to support the industrial transformation of the city. Following the famed reversal of the river, in which the city reversed the flow of the Main Branch and South Branch to improve sanitation, architect and urban planner Daniel Burnham introduced a new civic vision of riverside promenades with the addition of the Wacker Drive viaduct. Over the last decade, the role of the river has been evolving with the Chicago Riverwalk project—an initiative to reclaim the Chicago River for the ecological, recreational and economic benefit of the city.

几年前，由于河流的重度污染，滨河休闲是遥不可及的目标。但今天这个愿景成为现实。在水质方面的最新进展以及沿河公共休闲使用强度的提升都体现了滨河生活的增加，呼唤通向水岸的新的连接。响应这些号召，芝加哥交通部开始实施滨河步道项目，用新空间充实系统的各个部分，其中包括非常成功的退伍军人纪念广场与沃巴什广场。

The goal of embracing the river as a recreational amenity seemed impossible years ago given the river’s high levels of pollution. But today that vision is becoming a reality. Recent improvements in river water quality and the increased intensity of public recreational use signal growing life along the river, demanding new connections to the water’s edge. Accordingly, the Chicago Department of Transportation and Ross Barney Architects led Phase One of the Riverwalk, an initial segment that includes Veteran’s Memorial Plaza and the Bridgehouse Museum Plaza.

2012 年，Sasaki、罗斯巴尼建筑事务所、阿尔弗雷德本纳什工程公司以及广泛的技术顾问团队合作，任务是为州街与湖街之间的六个街区创造愿景。在先前河流研究的基础上，此团队提出的芝加哥滨河概念规划在湖泊与城市步行系统，以及河流在城市中的支流之间提供了最后的关键连接。

In 2012, the team of Sasaki, Ross Barney Architects, Alfred Benesch Engineers, and Jacobs/Ryan Associates, supported by technical consultants, was tasked with completing the vision for Phases Two and Three: six blocks between State Street and Lake Street. Building off the previous studies of the river, the team’s plans provide a pedestrian connection along the river between the lake and the river’s confluence.
