The Robertson Tunnel that allows TriMet’s Red and Blue Line MAX trains to connect Portland to the west side will close for a week to replace overhead wire used to power trains, and to replace about 700 feet of track between Washington Park and Goose Hollow.

During the closure, shuttle buses will take travelers between Sunset Transit Center and Providence Park station. The buses will also stop at the Washington Park station that serves the Zoo and other attractions. In some cases, regularly scheduled bus service may offer a faster or more direct option. Riders can begin planning their trips now at trimet.org/planner.

Some trips may take up to 45 minutes longer than usual. TriMet encourages riders traveling to and from Portland International Airport to be aware of the extra travel time and to plan ahead. Shuttle buses may fill up faster and have less room for luggage.

“The Robertson Tunnel, finished in 1998, was a huge engineering achievement, with features that are still unmatched today. Among the most notable, the Robertson Tunnel is home to the deepest transit station in North America, Washington Park MAX Station. It serves several destinations at the surface level (via an elevator) that carries travelers 260 feet above, the equivalent of the length of a football field. Destinations include Washington Park itself, along with the Oregon Zoo, World Forestry Center, and Hoyt Arboretum. Two popular gardens are also accessible: the Portland Japanese Garden and the International Rose Test Garden.”
