New Mid-Block Pedestrian Crossings on Boones Ferry Road

One of the many exciting features of the Boones Ferry Project is drastically improved pedestrian access. Two new mid-block pedestrian crossings with flashing beacons have been installed along Boones Ferry Road, and they are both quite unique. Watch our engineers share tips for navigating the new crossings.

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 started 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 underwater inspection of the Lake Oswego Interceptor Sewer continues through Winter 2021/22. Over the next few weeks, we’ll have two inspection barges plus specially trained dive crews working throughout Oswego Lake. Please keep an eye out and respect the 200-ft. no-wake safety zone.

This inspection work will help make sure the buoyant sewer pipeline that lies across Oswego Lake continues to serve the community reliably.
