Why have all of the secondary roads been disappearing in Portland, Oregon? It looks like someone has decided that only highways (e.g. roads that have a ref=) get to be secondary roads.
It seems like there should be a distinction between two and four lane roads. Looking at the current map, you have to guess the major streets. What's the point in that?
I can assure you that SE Hawthorne is more busy than SE Harrison. http://www.openstreetmap.org/?lat=45.5108&lon=-122.63488&zoom=16&layers=B000FTF

Tertiary network roads still get highlighted, just not at such low zoom levels.

The problem is roads which used to be tagged secondary, for example, SW 185th, SW Murray, SE Cesar E. Chavez, SW Stafford, E & W Burnside, are now tertiary. What happened to all of the primary roads?
