Blue Line (Hillsboro/City Center/Gresham)
Green Line (Clackamas/City Center/PSU)
Red Line (Airport/City Center/Beaverton)
Yellow Line (Expo Center/City Center/PSU)
Orange Line (Milwaukie/City Center)

MAX trains run about every 15 minutes most of the day, every day. Most lines begin service around 4 a.m. and finish before midnight. A wide variety of MAX Park & Ride locations allow you to leave a vehicle for up to 24 hours, free of charge.

A unique feature of the system, the MAX Orange Line uses Tilikum Crossing, Portland’s first new span since 1973 and the nation’s longest bridge dedicated solely to transit, bicycles and pedestrians. (The Orange Line connects downtown Portland to the Central Eastside, Sellwood and Milwaukie, a suburb to the southeast.)
