I'm looking at a house in the Rainier Beach neighborhood. Google Maps' bike route is no good, doesn't seem safe to ride day in and day out (the route includes a bunch of Lake WA Blvd, which seems too narrow and congested). I realize that Google isn't a great way to figure such things out, so is there a decent route from the south to downtown that has bike lanes, trails, etc.? I would be starting my commute near Roxbury and Rainier Ave.

Thanks for any info.
