(Portland, OR) -- TriMet has made major changes to its service. The MAX Green Line now only runs between Clackamas Town Center and the Gateway Transit Center. That means passengers traveling from the mall will have to change trains, if they're going downtown. Dozens of bus lines have been modified for efficiency. Two bus lines, 82-South Gresham and 153-Stafford, have been eliminated. Riders should check TriMet dot org to see if their lines are affected.
