The Southwest Corridor Light Rail Project is a proposed MAX light rail line that would provide a 30-minute trip between Downtown Portland and Tualatin. The high-capacity transit project was planned for one of the most congested travel corridors in the region, and to support the estimated 400,000 new residents expected by 2040. It would include coordinated investments to foster connected, affordable communities where all people can live, work and thrive.

TriMet, Metro and other project partners began planning efforts on the light rail line in 2009. From 2016-2020, TriMet and Metro worked on the preliminary design and environmental review phases of the project, resulting in the Draft Environmental Impact Statement and the Conceptual Design Report.

In November 2020, voters rejected Measure 26-218 (also known as Get Moving 2020), a proposal to fund the Southwest Corridor Light Rail Project and many other transportation programs across the region.

At this time, the project is on hold until funding is identified. A Final Environmental Impact Statement will be published in early 2021 to ensure the project is eligible for future federal funding.

The design and alignment concepts shown on this website are based on the Conceptual Design Report, published in September 2020. If the project were to restart at a future date, these designs could change.
