The Corellian Trade Spine was a major trade route. It began at Corellia and headed towards the edge of the galaxy, in the direction of Duro. It passed Devaron and Bestine IV before intersecting the Rimma Trade Route at Yag'Dhul. As it continued it passed through the Greater Javin region of space (which contains the Ison Corridor) before intersecting the Hydian Way and exiting into open inter-galactic space.
