VANCOUVER, WA — The Interstate Bridge Replacement Program (IBRP) – I-5 Bridge Replacement Nears Reality! Marked a major milestone this week as four key Columbia River stakeholders officially approved agreements supporting the effort to replace the aging Interstate 5 Bridge between Washington and Oregon.
According to program officials, the agreements were signed by representatives from commercial navigation, fishing, recreation, and tribal interests — groups whose approval was critical for the project to move forward. Each agreement outlines how the replacement project will protect river access, address environmental concerns, and minimize disruption to river traffic during construction.
Program leaders described the development as a turning point. Coordination with river-based users has long been one of the project’s most complex challenges, given the bridge’s strategic location and its impact on regional commerce and habitat.
“We now have essential partners on board,” said a program spokesperson. “These agreements reflect years of collaboration and commitment to ensuring this project benefits the region while protecting the Columbia River’s diverse uses.”
With the stakeholder agreements secured, the IBRP will advance to its next phase: final alignment studies, design refinements, and detailed environmental review.
Local officials praised the progress, emphasizing how vital the bridge replacement is for safety, freight mobility, and the local economy. The century-old bridge — a critical link between Vancouver and Portland — carries hundreds of thousands of vehicles daily and is considered seismically vulnerable.
A Washington transportation representative noted, “Replacing the I-5 Bridge is essential to keeping our interstate freight corridors safe and efficient. This is not just a transportation project; it’s an economic lifeline for both states.”
The next steps include releasing a draft Environmental Impact Statement (EIS), gathering public comments, and finalizing design alternatives. Funding negotiations are ongoing, with state and federal grants expected to play a major role.
Residents and businesses along the river corridor are encouraged to stay involved as planning continues. The program team says detailed schedules and updated design visuals will be released later this year.
