Interstate 5 Bridge Replacement Portland, Oregon, Washington

Interstate 5 provides a critical connection between Portland, Oregon and Vancouver, Washington. The bridge that crosses the Columbia River is a vital link for the pacific northwest, supporting the region’s jobs, communities, trade routes as well as the broader international economy.

Facilitating Development of a Vital Pacific Northwest Transportation Connection

Originally constructed in 1915, the aging structure is being replaced to deliver a multi-modal, seismically-resilient foundation of mobility for the region’s future. The bridge addresses safety and congestion issues while also displacing carbon and improving equity through job accessibility via improved transit. With implications that include the site’s scenic views, natural systems and a rich history within our national heritage, Otak is working to facilitate government relations, public affairs and communication to completion.
