I-5/columbia river interstate bridge - replacement

This $19,840,269.52 Formula Grant award from the Federal Highway Administration (CFDA 20.205 - Highway Planning and Construction) will fund a significant infrastructure improvement project in Washington state. The project will replace and update the aging I-5 bridges and North Portland Harbor bridges over the Columbia River, making them seismically resilient. It will also modify several interchanges in Oregon and Washington, add auxiliary lanes, install toll facilities, and enhance bus rapid transit and light rail service. The project includes the planning and development phase to reevaluate the scope, develop a financial plan, and engage stakeholders. The grant was awarded on September 23, 2024 to the Washington State Department of Transportation to execute this multimodal transportation infrastructure initiative.
