Browse Route 20 state gateway pages from Iowa to Oregon and across the strongest eastern and mid-route states before choosing segments, places, or trips.
States
Start with a state when you know the broad part of Route 20 you want to drive but have not chosen the exact towns yet. State pages are the easiest way to compare anchor towns, spot longer rural stretches, and decide whether to open a ready-made trip, a town-to-town segment, or individual place pages next.

Looking for narrower regional pages too?
Use the full regions index when you want the state gateways and the smaller subregional pages on one page. After a state page, the usual next move is one route section from segments, then one stop or anchor town from places, then a bounded weekend or drive from trips.
