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 email@example.com, 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.
All construction activities within the public right-of-way require an approved traffic control permit from the City of Lake Oswego. There is no fee for a traffic control permit.
We want your help in making community streets a safer and more comfortable place. While staff work diligently on addressing issues that are spotted, we understand that we can’t catch everything.
The purpose of Neighborhood Traffic Management Program is to give citizens greater participation in decisions regarding traffic management on neighborhood streets in order to promote the safety and livability of residential neighborhoods.
The McVey Avenue/Stafford Road Corridor Vision Study aims to identify potential street improvements to efficiently move people through this busy corridor and improve the safety for all roadway users, including those walking, rolling, riding, and driving. An online open house was recently held. More than 325 comments were received on the interactive map from October 12-28, 2022! Learn more about the project and upcoming opportunities.
Average Daily Traffic count information for most of Lake Oswego's major streets and some of our local streets is available online.
The City of Lake Oswego’s transportation system plan (TSP) is an important document for long-range planning purposes as well as a tool for current developments. It provides a snapshot of the existing system, immediate changes, and future plans into year 2035.
Flashing Yellow Arrow signals are the new standard for permissive left turn movements. A permissive turn is one that can be made through gaps in oncoming traffic.
System development charges are fees paid by new development to recover a portion of the cost of existing infrastructure and to help fund new infrastructure.
