Interstate Bridge Replacement Project

planned

The Interstate Bridge Replacement Program is a bi-state public works project to replace the Interstate Bridge over the Columbia River. The project includes building a new bridge designed to carry 180,000 vehicles per day, improving freeway ramps for five miles around the bridge, and extending light rail to Vancouver. Tolling on the new bridge is central to the project's funding plan, with an investment grade financial analysis conducted by engineering firm Stantec to evaluate tolling revenue scenarios and their impact on traffic and funding.
