MAX Green Line
light rail line in Portland, Oregon
The MAX Green Line is a light rail line serving the Portland metropolitan area in the U.S. state of Oregon. Part of TriMet's MAX Light Rail system, it connects Northeast Portland, Southeast Portland, and Clackamas, traveling 6.5 miles (10.5 km) and serving nine stations. It is the only MAX line that does not directly serve downtown Portland. Trains operate along the Interstate 205 (I-205) corridor between Clackamas Town Center Transit Center and Gateway Transit Center, where the line connects with the Blue and Red lines. Service operates for 21 hours on weekdays and 20 hours on weekends with headways of up to 15 minutes. It is the system's third-busiest line, averaging 11,202 weekday riders in May 2025.
Planning for light rail in Clackamas County began in the mid-1980s with one of two lines envisioned from Portland International Airport to Clackamas Town Center via the I-205 busway. Over the next decade, plans shifted from I-205 and culminated in the South/North Corridor project, which failed to secure voter-backed funding over several ballot measures. In 2001, the South/North project was partially revived with the two-phased South Corridor Transportation Project, which proposed light rail along I-205 and the Portland Transit Mall in its first phase. The I-205/Portland Mall Light Rail Project was approved in 2003, and construction began in early 2007.
