In 2015 through spring 2016, the Southwest Corridor Plan partners worked with communities to refine the vision for improving transportation in the corridor's communities. Based on public input and technical findings, the Southwest Corridor steering committee made several important decisions about potential high capacity transit alignments, creating a final set of alternatives to advance into federal environmental review.
In July 2015, the steering committee removed two transit tunnels from consideration: One would have run under Marquam Hill, and the other under the Hillsdale Town Center. Concern from area residents about community impacts and costs were two important factors in this decision. In May 2016, the committee removed a potential tunnel to the PCC Sylvania campus, while making commitments that the project would identify other investments to improve transit, bicycle and pedestrian access to PCC Sylvania and Marquam Hill.
In January 2016, the steering committee determined that Bridgeport Village is the most promising terminus for the line, meaning that it would not extend further south into downtown Tualatin. The committee made other adjustments to the potential high capacity transit alignment in the Tigard Triangle and Tigard Downtown areas and a small stretch of alignment adjacent to Interstate 5 in Southwest Portland.
Finally, in May 2016 the steering committee responded to community input and technical findings and selected light rail instead of bus rapid transit for the corridor, in part because of its ability to meet growing demand in the future.
Beginning in fall 2016, the project entered a yearlong federal environmental review period to study the project's potential impacts to the built and natural environment. This review will assist in the selection of a final package of transportation investments for the corridor.
