Inversion: Plus Minus, Steel sculpture near Morrison Bridge in Portland, United States
Steel angle iron sculptures form silhouettes that outline architectural shapes, creating a visual frame against the Portland skyline near the Morrison Bridge.
The sculpture draws inspiration from Phoenix Iron Works, an industrial foundry that operated in southeast Portland for several decades until 1957.
Artists Annie Han and Daniel Mihalyo designed these public art pieces as part of Portland's commitment to incorporate art into urban development projects.
These outdoor installations are accessible year-round along Southeast Grand Avenue, marking the pathway between Morrison Bridge and Hawthorne Bridge.
The negative space within the metal framework creates the appearance of transparent buildings floating above the street level.
