Stafford-65th-Elligsen Roundabout

Convert the two intersections to two roundabouts, widen the travel lanes to 12 feet, and add bike lanes.

We will also replace the culvert at Boeckman Creek under the intersection with a fish passable culvert, and add stormwater facilities to treat water runoff.

Clackamas County is partnering with Washington County and the City of Wilsonville since the intersection spans multiple jurisdictions.

 Proposed design for the two roundabouts.

  Drop in anytime to learn more about the project and ask your questions to transportation experts at our second in-person open house. Our engineering design team has created a 60% level layout for your review after listening to questions and concerns at the first open house a year ago. The next step will be final refinements to project design, then we'll prepare the project to be posted for construction bid next year.

• Visit the virtual open house
• Refining the proposed improvement design, utility coordination, and environmental permitting.
