The U.S. Coast Guard notified the Interstate Bridge Replacement Program (IBRP) on Jan. 16, 2026, that it will allow a fixed-span replacement bridge to be built across the Columbia River as proposed by the IBRP. A fixed-span bridge at 116 feet vertical navigation clearance was identified by them as the best option to replace the aging Interstate Bridge between Vancouver and Portland.
“The U.S. Coast Guard’s decision is a major milestone along the path to a modern, multimodal fixed-span bridge that eliminates bridge lifts and improves safety and earthquake resilience” read a statement from the IBRP.
The decision clears the way for other important steps. Organizers can now finalize and share an updated cost estimate and schedule. It also allows for the completion and publication of the Final Supplemental Environmental Impact Statement, a key step toward securing a Record of Decision and moving to construction.
The IBR Program can also begin the process of selecting a final design for the replacement bridge and identify a construction contractor.
“The IBR Program now has the clarity it needs to advance and position us to build a safer, multimodal river crossing and corridor that will serve both states for generations,” said Oregon Governor Tina Kotek.
