Walk the Walk

Infrastructure is essential to the operation of a city.  Without it, people would not be able to easily access urban nodes throughout the city fabric, causing development and density to suffer from a lack of activation.  So powerful is this element in the forming of metropolises, that it becomes one of the defining characteristics of the city’s identity.  Hong Kong is identified by its elevated walkways.  These causeways are so efficient at moving people between different city nodes because it removes cars, roads, crosswalks and other complications that slow pedestrians down at the street level.  They are also successful because of their connection to these nodes, and the major urban programs they service such as shopping centers and transportation hubs.

It is interesting to see this same strategy utilized at the 2010 World Expo in Shanghai, only at the scale of a micro-city.  The expo is situated across a large area bordering the Huangpu River on both sides.  Spanning the entire distance of the elongated site is an elevated walkway, serving as the main artery for people movement between different zones of the expo.  Like Hong Kong, this walkway is equally successful at achieving a lubricated system of movement through a larger fabric.  It bypasses the congested masses and long queues of expo-goers at the ground level, and also serves as an access-way to move between critical expo nodes such as food courts, subway stops, shopping malls and several major pavilions.

What’s left to consider is what will become of this walkway once the expo has expired.  Hong Kong’s walkways have been in place for some time, and as a result of the high rate of pedestrian traffic, new programs have began to attach themselves to these arteries, and use them as a host.  It is common to find small retail, food stands and convenience stores along the way, between the larger nodes that anchor the terminal points of the walkway.  Unfortunately in Shanghai’s case, the end of the expo means the end of many of the pavilions and other programs, which were only temporary installations.  If the site is revitalized post-expo however, it is probable that the area will be developed into high-rise housing structures, with mixed use at the ground levels.  If the walkway is left in tact, it will certainly be an integral part of the infrastructural network linking this new development with the urban node located at the waterfront, which encompasses our final design task.  Weather or not parasitic programs attach to this artery in a way similar to Hong Kong is dependent upon its linkage to the nodes which will arise out of redevelopment.  Of course, this will be a crucial element to grapple with during the next seven weeks.
