Traffic Engineering and Transportation

The Lake Oswego Transportation System includes more than 178 miles of streets, 32 traffic signals, 12.0 miles of pedestrian pathways, and shared ownership of the Jefferson Street Rail Line (aka Willamette Shoreline Trolley) within the city limits. The streets are classified as major and minor arterials, major collectors, neighborhood collectors, and local streets; traffic counts are available on line.

The City’s Transportation System Plan (TSP) provides a plan for the development of the City’s transportation infrastructure. Specific projects are further developed as resources become available. The TSP includes elements for roadways, bike, pedestrian, transit and rail related improvements.

Concerns, comments and questions regarding traffic related matters can be sent to, and a staff person will respond.  Make sure to include your contact information if you would like a response. For more information, please contact the Engineering Department at 503-635-0270.
