Two new MAX stations will open at Portland State University, making it easier to access more of the campus directly by transit.


Go here and scroll down to the third paragraph to see more.

Looking back to our 2010 visit, this extends the downtown transit mall, where the Yellow & Green Lines run on a parallel streets couplet, one stop further than before. We already got the trackage when we rode the heritage streetcar, which makes the loop with passengers aboard whereas MAX doesn't (the operators layover between runs there).
