[1] Together, they serve as the southern passenger terminus—one for departures only and the other for arrivals only—of the Portland Transit Mall MAX line.

[1] Those development plans were finalized in 2010,[3] and construction of a new 16-story residence hall on the block began in November 2010,[4] for opening in 2012.

For the first three years of MAX service on the Portland Mall, from 2009 to 2012, the PSU Urban Center/Southwest 6th & Montgomery Street and PSU Urban Center/Southwest 5th & Mill Street stations temporarily served as the southern terminus (for passengers) of the Green and Yellow Lines.

Except on Orange Line trains, passengers heading southbound are required to disembark at this station.

The loop originally had three tracks, but one of them was removed when the Orange Line was built through the station.
