The Columbia River Crossing (CRC) is a proposed highway bridge replacement for the current span of Interstate 5 over the Columbia River connecting Portland, Oregon and Vancouver, Washington. The $3 billion infrastructure improvement has been envisioned by transportation planners over the last twenty years and has recent run aground against local opposition to the project by environmentalists, livable community activists and nearby residents most likely to be negatively impacted by this proposal. While any project of this magnitude is inevitably going to garner significant discussion, this website specifically focuses on the controversies surrounding the political process through which this project was designed, the usage of objective "science" in the advocacy for and against this bridge, and how these topics relate to the project's ultimate architectural design, amenities, cost, and environmental impact.
