Unable to answer "Are pedestrians forbidden to walk on this road here?" for https://osm.org/way/254968971 via StreetComplete 45.2:

There is no sidewalk on the north side of Lincoln.  There is an ordinary sidewalk on the south side, which should probably have a separate way added.  Photo is looking west from sidewalk at 36th & Lincoln, onto the sidewalk on the bridge over Sunset Blvd.
