I-5 Rose Quarter Improvements

Portland, OR

Our team is the Engineer of Record for all major retaining and structural walls involved in this project, and we are providing comprehensive structural engineering support for new local street connections and infrastructure improvements along the Interstate 5 corridor. This project covers the area from the I-405 junction to the Morrison Bridge exit and includes significant upgrades to the Broadway/Weidler Interchange. Our scope of work includes conducting detailed seismic evaluations of nine bridges within this segment and designing Phase 1 seismic retrofits for eight of these structures to enhance resilience and safety. Additionally, we are collaborating closely with project stakeholders to ensure seamless integration of the improvements with existing infrastructure while maintaining high standards of safety and durability.
