The average daily traffic in 2000 was 23,100 vehicles (including many TriMet buses), 200 MAX trains, 40 freight and Amtrak trains, and 500 bicycles. The construction of the lower-deck walkway connected to the Eastbank Esplanade resulted in a sharp increase in bicycle traffic, with over 2,100 daily bicycle crossings in 2005. MAX traffic has tripled since 2000, when only the Gresham–Hillsboro line (now the Blue Line) was using the bridge, to 605 daily crossings (weekdays) as of 2012. This resulted from the addition of three more MAX lines during that period: the Red, Yellow, Green Lines.
