Arco
On Route 20
Arco is the current central Idaho handoff point into the broader interior Idaho continuation on the live Route 20 build.
Practical Route 20 utility context
Big Lost River Rest Area can be a useful reference point when you are planning the Arco-to-Idaho Falls high-desert stretch. Confirm current access, closures, rules, and facility status before relying on it, and do not treat it as an overnight-stay recommendation.
What it pairs with
Arco pairs best with Idaho Falls, Carey, the Rexburg, Idaho Falls, and Arco segment, the Arco, Carey, Picabo, and Fairfield segment, and the Arco to Fairfield Route 20 Weekend when you want the clearest current handoff from the earlier central Idaho build into the broader interior continuation.
