Here at Public Works, we take pride in providing utility maintenance to help make Lake Oswego a great place to live.

News & Announcements

North Shore Road Bridge Closed

To maintain public safety, the North Shore Road Bridge is closed to vehicular traffic until further notice. A temporary access route has been established over the bridge for people walking, rolling, and biking. 

The City recently identified structural concerns with the retaining wall near the bridge. We are investigating the conditions of the retaining wall and conducting a structural analysis over the coming months. Long-term closure may be needed. 

Please use alternative routes and keep North Shore Road for local traffic. We will keep you informed about the wall condition, updated timelines, and closure plans as we learn more.
