There's a point on WA525 at what appears to be where the current alignment departs from the location of an old alignment. This is labeled as "106thSt", though for the life of me I have no idea why. (The route does in fact intersect 106th Street, but it's a minor intersection roughly two miles north of where this point is.) Would suggest perhaps renaming to OldMukSpe (or whatever the appropriate abbreviation for "Speedway" is).
Also, would it be appropriate to add a point at Beverly Park Rd? Used that yesterday as a route to Paine Field, I think due to traffic on WA99. If not, no big deal.
