Cascadia High-speed Rail Status, Cost, and Route Map 2026
The Cascadia High-Speed Rail is a proposed 315 mi high-speed passenger rail system connecting Vancouver, British Columbia, Seattle, Washington, and Portland, Oregon, with the cascadia high-speed rail serving as the Pacific Northwest's flagship megaregional transit initiative. Spearheaded by WSDOT alongside regional partners and supported by FRA corridor identification grants, official plans aim to provide 250 mph service along the Interstate 5 corridor. Funding model framework relies on combined Federal Grants and State Appropriations to secure necessary right-of-way and conduct early planning. Strategic importance centers on mitigating highway congestion, reducing regional greenhouse emissions, and linking major economic hubs across state and international borders. As environmental review processes and preliminary engineering advance, stakeholders continue refining the proposed route map and preliminary alignment alternatives. While an exact completion date remains targeted for the late 2030s or early 2040s, initial technical analyses demonstrate strong economic return on investment for the region.
