Inversion: Plus Minus, Steel sculpture near Morrison Bridge in Portland, United States
Inversion: Plus Minus is a steel sculpture near the Morrison Bridge in Portland, composed of angle iron that forms architectural silhouettes. The metal framework creates a visual frame against the skyline backdrop and runs along Southeast Grand Avenue between Morrison Bridge and Hawthorne Bridge.
The sculpture draws inspiration from Phoenix Iron Works, an industrial foundry that operated in southeast Portland for several decades until it closed in 1957. This artistic creation honors the region's industrial heritage and weaves that history into the contemporary art landscape.
The artists Annie Han and Daniel Mihalyo created these public artworks as part of Portland's initiative to weave art throughout urban development projects. The installations shape how people experience the streetscape and encourage viewers to see their surroundings in new ways.
The installations are accessible year-round and free to visit as you walk along Southeast Grand Avenue. The location between the two bridges makes these sculptures a natural part of exploring the neighborhood on foot.
The negative space within the metal framework creates the appearance of transparent buildings floating above street level. This optical effect emerges from how the steel frames interact with the urban backdrop, offering viewers a distinct perspective on the architecture around them.
