I-5 through North Portland used to be called Minnesota Freeway much more often; the term has mostly fallen out of common use today. Remnants of North Minnesota Avenue are seen disappearing underneath the Going Street overpass in this 1963 photo. Skidmore Street is the east-west street just above the label on the photo.

Well, this sort of explains why the freeway is so small by today’s standards. They would have had to condemn twice as many residences to get the proper footprint needed for a real big city freeway.
I remember that pit very well.
