Quickest would be I84 on the Oregon side. I would rather take 14. Better view of the river and dams/locks. There are several ways to go - all freeway or almost all secondary. There is some very nice scenery either way. I might opt for 14, then jog down to 730 at Umatilla then 12 Walla Walla, then 12 to Lewiston then 95 to Coeur d' Alene. But that's me - YMMV.
