There wasn't a damn thing I could do or say
Up in the skyway
~The Replacements
An empty downtown, with boarded-up shops and desolate sidewalks, is truly a sad sight to behold. It is also symptomatic of much larger forces, namely the flight from the urban core into the suburbs that wound up decimating the vitality of American cities during the second half of the 20th century. Last month I argued that the urban form of the skywalk was a partial and misguided response to reviving the emptied-out downtowns of American cities. In most instances these structures, which sought to connect buildings without touching the street, were a prolonged, painful failure, because they further segregated street life and did not succeed in drawing people back into that urban core, at least in a way that could be considered dynamic and responsive to the larger needs of the urban fabric. In a sense, much was expected of skywalks, but in fact they were little more than a Band-Aid, and served to only exacerbate the problem through the fundamentally anti-social tendencies that underlie their design and use.
And yet, like any other urban form, skywalks are agnostic – what determines their success is not just their design and implementation, but also the problem that they seek to address. It is perhaps more accurate to say that skywalks, along with many other forms of intervention in the urban built environment, reveal the question that designers have posed themselves, believing that that question, whatever it might be, is in fact the correct and most pressing one. So, in the case of American cities, skywalks were employed to revive downtowns, and, generally speaking, failed. Other cities around the world have enlisted skywalks not because there is too little density, but because there is too much. Does this new context increase the possibility of success? In order to understand what a difference a difference makes, we first need to consider the forces that shaped cities in the West, and what the difference might be between this phenomenon and that of the global urban South.
The narrative describing the development of American cities can be retold as a narrative of excessive space. When energy and labour are cheap, economic logic drives growth outward; it is always easier to build on virgin ground rather than re-organize an existing built environment. This is especially true when urban areas are not bounded by geographic obstacles such as water or mountains – a condition true of most mid-Western cities and not a few coastal ones.
