Interstate Bridge Replacement: 2026 Status, Cost & Timeline
The Interstate Bridge Replacement is a critical 5 mi infrastructure program modifying the I-5 corridor across the Columbia River, providing a comprehensive interstate bridge replacement between Portland, Oregon, and Vancouver, Washington. Led jointly by ODOT, WSDOT, FHWA, and FTA, the modern multi-modal megaproject addresses seismic vulnerabilities, severe congestion, and freight bottlenecks along this vital Pacific Northwest commerce highway. Operating under an IIJA Federal Grants & Tolling funding model, official plans incorporate highway interchange reconfigurations, light rail transit extension, and active transportation paths. The refined route map and bridge alignment focus on minimizing right-of-way impacts while enhancing corridor capacity and safety. Currently progressing through environmental review and federal approvals, the project aims for construction initiation followed by a targeted completion date of 2033. This vital crossing replacement secures long-term multimodal regional connectivity, economic sustainability, and resilient interstate commerce across state lines.
