North Shore Road Bridge Closure

During a July 2021 inspection, the City discovered cracks and movement in the retaining wall on the east side of the northern approach to the North Shore Road Bridge, which supports the approaching roadway. In October, the design team will begin performing detailed testing and analysis of the retaining wall and surrounding area to determine the extent of the defects. 

To maintain safety, the bridge and roadway remain closed to vehicular traffic until the structural analysis and any recommended repairs are completed. At this preliminary stage, we are hoping to reopen the bridge in spring 2022, however this is subject to change.

Proposed New Wastewater Treatment Facility

The Tryon Creek Wastewater Treatment Plant is aging and needs major upgrades to continue to reliably meet Oregon Department of Environmental Quality (DEQ) water quality requirements. Lake Oswego and Portland are exploring building a new wastewater treatment facility to replace the old plant.  

The project is in the early stages of design. For more information about the project, or to sign-up for e-news, click here

Lake Oswego Interceptor Sewer Inspection

The City is performing a routine underwater inspection of the Lake Oswego Interceptor Sewer through Winter 2021/22. This work will help make sure the buoyant sewer pipeline that lies across Oswego Lake continues to serve the community reliably.

The City will be using barges to deploy divers and robotic cameras to inspect each segment of the pipeline. Boaters are asked to respect the 200-foot no-wake safety zone where work is occurring.
