I believe it still is. The recent change was the addition of the bus lines (w/ bikes allowed) on Rainier *north* of Rainier/MLK intersection--AFAIK this segment of Rainier has been signed like this for several years now.

This note is on my radar but I haven't been down to this area to survey for a while. I think I got the lanes updated Rainier from MLK through I-90, but everything's messed up south of MLK.
