How the interchange evolved
Historically, transport infrastructure was the domain of engineers, with little attention given to aesthetics or to people. Engineers determined the path of railways and canals, later roads and the location of airports and ferry terminals. It is infrastructure that gives the primary figure ground to landscape and the engineers who design the infrastructure determine also the shape of cities and the location of transport facilities. Their impact extends over a long period of time and the different forms of infrastructure, from transport systems to water supply,
provide one of the key agencies in achieving sustainable development. Only recently have architects become involved in infrastructure design beyond that of cosmetic effects. However, recent investment in public transportation systems, and in interchanges in particular, have opened up new opportunities for architects. Architects are now appointed alongside engineers in order to bring order and beauty to the interface between transport infrastructure and the city.
