I-5/columbia river interstate bridge - replacement

This $4,636,414.54 federal Formula Grant award from the U.S. Department of Transportation's Federal Highway Administration (CFDA 20.205 - Highway Planning and Construction) is for the replacement and modernization of the I-5 bridges over the Columbia River between Oregon and Washington.

The project will replace the existing bridges with new seismically resilient structures, modify several interchanges, add auxiliary lanes, install toll facilities, and enhance bus rapid transit and light rail service across the new bridges. The award will also fund the planning and environmental permitting work required to reevaluate the project's purpose and scope. This grant is part of the Department of Transportation's broader efforts to improve transportation infrastructure, safety, and multimodal connectivity across the United States.
