Southwest Corridor Plan

Design work on the Southwest Corridor Light Rail Project was paused in 2020 after voters rejected a local funding measure for multiple transportation improvements. In the meantime, Metro, TriMet and the Federal Transit Administration continued working to complete the Final Environmental Impact Statement (FEIS) and issued a Record of Decision (ROD) to ensure the project is eligible for future federal funding.

Planning a new light rail in the Southwest Corridor

Southwest Corridor: Time gained

From Tualatin and Sherwood to Tigard and Southwest Portland, more people are choosing to live, work and play in the Southwest Corridor. The Southwest Corridor Plan was a comprehensive vision for the investments needed to keep this area moving and support the people who live here as the area grows.

Metro created an Equitable Development Strategy with local partners to explore how a proposed light rail and other investments can support community development and improve the quality of life for people of all incomes and backgrounds. To learn more about the Equitable Development Strategy and related ongoing work, see the Southwest Corridor Equitable Development Strategy page.

Voters did not approve Measure 26-218, which would have funded multiple transportation improvements in the region, including the proposed MAX Light Rail line in the Southwest Corridor. As a result, design work on the project is on pause. In the meantime, Metro, TriMet and the Federal Transit Administration continued working to complete the Final Environmental Impact Statement (FEIS) and issued a Record of Decision (ROD). Click the "Environmental review" tab above to access the FEIS and the ROD.

See the TriMet project website for more details on the light rail project design.

To qualify for federal financial support, the project must comply with the National Environmental Policy Act. The Federal Transit Administration determined that an Environmental Impact Statement, or EIS, was appropriate. Scoping for the environmental process occurred in September 2016. A Draft EIS (DEIS) was published in June 2018.

The Final EIS (FEIS), which was made available in January 2022, presents information about the project's potential impacts and benefits, and specifies strategies to minimize or mitigate significant impacts. Appendix J of the FEIS includes responses to tribal, agency, and public comments received on the DEIS. On April 8, 2022, the Federal Transit Administration issued a Record of Decision (ROD) on the project's compliance with the National Environmental Policy Act and other environmental requirements.

What is a land use final order?

A land use final order is a single land use permit for the proposed light rail line. Rather than TriMet seeking land use permits from each city and county for just that portion of the project that is within each jurisdiction, the land use final order is a single permit for the entire light rail line granted by one entity (Metro). Land use final orders have been granted in the past for all MAX lines in the region. In addition to the land use final order, the new light rail line will need to obtain federal, state and local permits related to the design and construction of the project.

The Southwest Corridor Light Rail Preferred Alternative is the alternative identified as the favored course of action to meet the project’s purpose and need. The Southwest Corridor Steering Committee recommended a preferred alternative based on analysis documented in the Draft EIS; input from the public and agencies, including comments on the Draft EIS; the project staff recommendation; and consideration of FTA’s rating criteria for large transit projects. The directly affected local jurisdictions, including the TriMet Board of Directors, adopted resolutions of support for the steering committee recommendation, and Metro Council took these resolutions into consideration in their approval of the Preferred Alternative and its incorporation in the Regional Transportation Plan.

The Preferred Alternative would have constructed an 11-mile extension of the MAX system from Portland State University to Tigard and Bridgeport Village in Tualatin. The project would have provided the backbone for enhanced local bus service in the Southwest Corridor and would make substantial investments in the transportation infrastructure of the Southwest Corridor including:

a shared transitway that allows for express bus service from Beaverton and Hillsdale into downtown Portland
continuous sidewalks and protected bike lanes on both sides of Barbur from I-405 to Barbur Transit Center
improved pedestrian connections to the OHSU and VA complex on Marquam Hill and to Portland Community College’s Sylvania campus
a rebuilt driving surface for Barbur including reconstruction of two aged viaducts
greatly enhanced stormwater treatment along Barbur to support a cleaner Willamette River
a new operations and maintenance facility for TriMet MAX vehicles

For reports about alternatives considered prior to the selection of the Preferred Alternative, such as the comparison between light rail and bus rapid transit, send an email to [email protected] or call 503-813-7535.

These documents provide the background leading up to selection of the Shared Investment Strategy, the core approach adopted for the Southwest Corridor Plan in 2013, including public input from initial outreach and existing conditions analysis. Updates on the strategy are also included below.
