Rough diagram of TriMet bus service distribution on 3rd Avenue in central Portland while the Portland Mall is closed.  Made from scratch by me, Jason McHuff, using Inkscape.
Notes:  Buses enter 3rd Avenue at the place on the top, stop at the stops designated by the letter in the center and leave 3rd Avenue at the street indicated below that.  Streets/bridges that these buses use to leave the central city are also shown.
