WA-127 is on the NHS map.  You could call it "important" or
"significant" in the sense that it's part of the shortest route from
Walla Walla to Spokane, and the only bridge across the Snake River for
50 miles in either direction, but that doesn't make it important in any
absolute sense.  The state DOT estimates that it sees maybe 800
vehicles a day, and if it doesn't have a "Next gas: 65 miles" sign,
it's only because nobody bothered to put one up.
