Oregon Department of Transportation—I-5: Fern Valley Interchange Project

This $72 million diverging diamond interchange project in Phoenix, Ore., transformed a region, improving quality of life and starting a fresh vision to encourage future growth. Before this project, a two-lane interstate bridge near another load-limited bridge existed, with neither bridge able to accommodate sidewalks or bike lanes. Morning and evening commuters endured severe traffic congestion in the interchange area and along nearby Oregon 99. After much discussion with the local community, ODOT landed on a design that worked for everyone. Construction began in spring 2014 with the goal of keeping the community connected to local businesses while building a new bridge and ramps next to the older bridge (a goal that was met). When all was said and done, the interchange was completed with new multi-modal facilities such as new bike and pedestrian facilities throughout the interchange area and a new transit stop.
