Research and Enlightenment of City Skyway in America: A Case Study on Minneapolis

自20世纪60年代以来,城市空中连廊(也被称为人行天桥系统)已成为世界各地许多城市的重要功能之一。城市空中连廊不仅是城市中心区规划建设的持久性话题,也是城市设计学术界颇具争议的话题。美国是最早进行城市空间连廊建设的国家,明尼阿波利斯也拥有全世界最大的网络化城市空中连廊系统。本文以明尼阿波利斯为例,对美国城市空中连廊规划的历史背景及成因、建设进程、优秀经验以及存在的问题进行深入剖析,并从中总结城市空中连廊可持续发展的规划对策。同时,结合我国城市建设的现况,提出城市空中连廊规划及建设的相关建议。

Since the 1960s, city skyway （also known as pedestrian overpass system） has become an important feature of many cities around the world. City skyway is not only a persistent topic in the planning and construction of the urban center, but also a controversial topic in urban design academia. America is a pioneer in the construction of city skyway. Minneapolis in America also has the longest and most continuous city skyway system in the world. Taking Minneapolis as an example, the article makes a thorough analysis of the historical background and causes, construction process, excellent experience and the existing questions. And then it summarizes the sustainable development strategies of the skyway system. At the same time, combining with the current situation of China＇s urban construction, the article puts forward the relevant suggestions of the planning and construction in the city skyway system.
