Interstate 9 was a relatively short highway serving the Pacific Northwest states of Oregon and Washington, but now it's been extended into northern California as well.  Its route incorporates a good portion of Interstate 82, and because of that, I've rerouted I-82 eastward to Lewiston, ID (more on that later).  The exits here are arranged from south to north.
