Freeway Park

This guide to Freeway Park in Seattle follows Angela Danadjieva, a designer trained not as a landscape architect but as a film set builder in Sofia, Bulgaria, before she joined Lawrence Halprin's office and took on an odd commission: hide six lanes of interstate under a park. It traces how she treated concrete like a soundstage, sculpting it into canyon-like walls over a lid built the same way as the parking garage beside it. The guide follows the park's 1976 opening as the first of its kind built directly over an active highway. Put your hand on the concrete and feel how deliberately rough it still is.
