TriMet buses and MAX trains provide frequent service in the district, as well as a commuter express bus route form Vancouver via C-Tran.
When the Portland International Airport was suffering from heavy road traffic coming from increased passenger service, and the Port of Portland was running out of land for new parking lots, the Port approached TriMet about bringing MAX to the airport, following through on a plan that dated to highway construction in the 1970s which had left room for such a connection.
An expansion of the school's campus starting in 2007 was influenced by the extension of TriMet's MAX Light Rail to Clackamas Town Center.
The final day of service is scheduled to be December 22, 2013, as a result of a decision by TriMet on December 11 to sell the two remaining Gomaco-built streetcars to a group planning a streetcar line in St. Louis, Missouri.
