Ultra-high speed rail study

Planning study news

The Cascadia High-Speed Rail study is now coordinating with WSDOT’s I-5 Master Planning Study to address the future transportation needs of western Washington communities. The integrated Cascadia High-Speed Rail and I-5 Program allows us to look holistically at highway, rail, and other travel options.

In progress


WSDOT is studying how high-speed ground rail might serve as a catalyst to transform the Pacific Northwest. A stronger, better connected economic megaregion — stretching from greater Vancouver, British Columbia to metro Seattle, Washington to Portland, Oregon — has the potential to thrive in the global marketplace. A key component of that vision is a fast, frequent, reliable and environmentally responsible transportation system that unites this Cascadia megaregion, and positions it for global competitiveness and future prosperity.
