Substructures
A substructure is the name for the architectural elements (abutments, piers, bents) that support the deck of a bridge. In bridges built using the arch, girder, and truss systems popular in the late nineteenth through the late twentieth centuries, substructures create spaces that run below the deck like hidden passages or open tunnels. They are often missing a floor so that their space extends downwards, into the surrounding landscape. Highly engineered, but not designed for public access, these images reveal moments of dissonance and spatial juxtaposition that reframe the bridge’s relationship to the landscape.
