TriMet 3rd/4th Aves stop spacing
Diagram of TriMet bus stops on 3rd and 4th Avenues in central Portland, Oregon while the Portland Mall is closed for construction.
It is a "reverse couplet"--northbound is on the left (on 4th) and southbound is on the right (on 3rd). Letters (and pound signs) designate stops. Numbers show amount of blocks buses travel between stops. On the old mall, buses stopped every 2 blocks; on the new mall, it will be about every 5. Official info is here.
