Owner’s Representative for the Sellwood Bridge Replacement

Location: Portland, Oregon

The Sellwood Bridge spans the Willamette River, connecting the Sellwood and Westmoreland neighborhoods in southeast Portland to the west side of the city and Macadam Avenue. Multnomah County completed an environmental impact statement (EIS) supporting a decision to replace the aging, deteriorating bridge. Given the highly political and complex nature of the design, public engagement, risk, and intergovernmental coordination of this project, the county hired DEA as its owner’s representative in 2010 to assist with project delivery.

DEA is working with the county to successfully deliver a high-profile, multimodal bridge and roadway project under the Construction Management/General Contractor (CMGC) model. DEA has supported the county through the TIGER III grant application process, securing $17.7 million for the project. DEA is providing team coordination, strategic decision making, and leadership through the design and construction phases. This multimodal bridge and roadway project has a budget of approximately $300 million and a four-year construction delivery schedule.
