“Oregon Department of Transportation Got Their Freeways On South Portland is a tour of the streets and spaces under and around the extensive freeway and highway infrastructure in South Portland. We’ll see, but mostly not ride on, the world-renowned (for how seismically unsound it is) Marquam Bridge, the Ross Island Bridge, the infamous Harbor Drive that was never removed, Macadam, I-5, I-405, Naito, Barbur, and some sketchy tunnels. You’ll also learn about why the street numbers go backwards and how to get around the freeway when the elevator is broken.”
