Stafford-65th-Elligsen Roundabout

Convert the intersection to a roundabout, 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 will partner with Washington County, Clean Water Services and the City of Wilsonville since the intersection spans multiple jurisdictions.

Why

To reduce congestion and improve safety for all travelers, and provide safe passage for fish and other wildlife though waterways.
