So there's an interestingly signed business loop of WA 240 in Richland. Starting from the "West" end (more of a north end but 240 is signed E-W), it follows Jadwin Ave all the way to George Washington Way to WA 240 at I-182 Exit 5. Going the other direction, however, signage follows GW Way north to McMurray St. then over to Jadwin and up to 240. Both sides are signed about equally well.
