Regional construction impacts

Construction noise in West Linn

Over the next couple of months, there is demolition work planned in West Linn on the north and south side of I-205. Crews are working to remove the concrete deck of the former elevated on-ramp from OR 43 to I-205 north. This ramp was replaced with the new roundabout that opened in 2023. The work is planned for approximately two weeks and will happen during nighttime hours.

In mid-March after the concrete removal is complete, crews start the removal of the elevated on-ramp itself along with the columns below the I-205 southbound off-ramp to OR 43. This will take approximately 3-4 weeks and most of the work will happen during the day, but some of the work may continue into the evening.

Nearby residents and businesses may hear noise from this demolition work. Use the 24/7 noise hotline to report any noise concerns: 503-276-7809.

As with any construction project, closure dates and timing are subject to change due to weather or other unforeseen events. Please continue to check back for ongoing updates.
