Behind the Campanhã railway station on the eastern edge of Porto, an elevated concrete walkway cuts north across the landscape, turning sharply where it meets a roundabout and then continuing on a viaduct over a hillside. From this vantage point, one looks out over a tangle of tracks and platforms on one side and an old, low-rise residential neighborhood, bitten into by an eight-lane highway, on the other. The rush of traffic, the clash in scales, the division of the city wrought by infrastructure: Campanhã represents a familiar landscape defined by conflicting ways of occupying and moving through space.
