I-5 Bridge Replacement Cost and Timeline Delayed Until 2026
The replacement cost estimate for the Interstate 5 bridge between Portland and Vancouver has been delayed until at least spring 2026 due to the U.S. Coast Guard's decision on whether to include a movable section, which could significantly increase costs. The project, with an initial estimate of $5-7.5 billion, is expected to begin construction in mid to late 2026, with ongoing funding and design considerations.
