Reply to "3-Shelf/4-Level Around-the-Walls with Peninsula and Helix: Atlas-O, O72min."

Extending the helix, but offsetting a top-level O72 loop to reach 20" (this top level helix loop only, is at 4%), which then climbs to meet the upper level at 24" on the run across the peninsula. Bridges shown, but probably trestles. Roughed in for concept.
