Full Route 20 segment index for the current guide.
Segments
Use segment pages when you want the route in connected town-to-town stretches. This page lists every current segment page on the site. Use a state page first when you want the broad planning layer, then come here to break that state into a more usable drive. The easiest western segment flow right now is eastern Iowa to western Iowa to Nebraska to Wyoming, then the Yellowstone east approach, west re-entry, Idaho continuation, and Oregon finish.
