The road beneath the lawn
This riverfront lawn once carried the lanes of Harbor Drive.
Harbor Drive ran along the west bank of the Willamette through downtown. Oregon closed this stretch in 1974, crews removed the roadway, and the new park opened in 1978. Portland's project became an early example of urban highway removal. The lawns around Salmon Street Springs still follow the former road corridor.
