As we work toward Oregon’s clean energy future, we’re strengthening the energy grid to make it smarter, more efficient and more reliable for you. Among our many projects, we’ll soon upgrade power lines along Highway 43 between downtown Lake Oswego and Marylhurst.
This project will help reduce outages and also provide a more reliable source of power for the Lake Oswego/Tigard Water Treatment Plant.
In preparation for the new lines, we first need to trim and remove some trees along the power line rights of way.
Tree maintenance(Approved by Oregon Department of Transportation)
- Mid-August through End of August
- 9 a.m. to 3 p.m., Monday through Friday
Power line upgrades(Approved by Oregon Department of Transportation)
- August through October
- 9 p.m. through 5 a.m., Sunday night through Friday morning
This schedule may change based on the needs of the project. While not anticipated, weekend hours might be required at times.
Why are we doing this work?
We’re working closely with the City of Lake Oswego and the Oregon Department of Transportation on this project. The extra tree maintenance and power line upgrades in this area will help ensure both reliable power and reliable water service.
Because the neighborhood has thick tree growth, before we upgrade power lines, we’re taking extra steps to prune and remove trees — most already dead — that would pose a hazard to the lines and our linemen. These steps and the line upgrades will also help ensure reliable power for the city’s water treatment plant, which delivers clean drinking water to Lake Oswego and Tigard.
What can you expect during this project?
You’ll see tree crews from our contractor, Asplundh Tree Expert, working along the areas highlighted on the map above. They will be trimming branches and removing dead or diseased trees from the power line rights of way.
After the tree maintenance work is complete, line crews will upgrade the power lines along this stretch of road.
Highway 43, managed by the Oregon Department of Transportation, is a busy commuting route. To minimize disruption during morning and evening commutes, ODOT has permitted nighttime hours for our work.
Important traffic and safety tips
We’re taking steps to ensure your safety. Here’s how you can help:
- Watch for temporary lane closures and “no parking” signs that may be needed for safety. Allow extra time for commuting through the area shown on the map, or consider alternate routes. Since we’re working at night when visibility is limited, please be especially cautious driving through the work zone.
- Follow directions from any flaggers, detours and signs placed to keep drivers, pedestrians and workers safe.
- Please avoid all work areas and equipment, and make sure children know to never touch the equipment.
Building a brighter energy future for you
The new power lines will boost reliability and reduce the risk of outages for the Lake Oswego/Tigard Water Treatment Plant and the surrounding neighborhoods. The upgrades will also improve overall system operations for all customers. This is just one of many projects we’re working on to modernize the energy grid, making it smarter and more resilient, and creating a platform for a clean energy future.
Thank you for your patience as we strengthen the energy grid.
