    "note": "The proposal states ~26 miles for Boise → Meridian → Nampa. The straight I-84 chord between the Boise and Nampa city centres measures shorter than that, because downtown Boise sits several miles off the interstate: any alignment that actually serves the three downtowns has to leave the freeway. The existing rail corridor between the same two cities measures closer to the stated figure. Both rights-of-way are drawn on the map so the reader can see which assumption the 26-mile number rests on."
