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.
Crews will also be removing the elevated on-ramp itself along with the columns below the I-205 southbound off-ramp to OR 43. Most of the work will happen during the day, but some of the work will continue into the night.
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.
Overnight directional closures of I-205 across the Abernethy Bridge
Starting the night of June 20 and continuing several more times over the summer, there will be overnight directional closures of the I-205 Abernethy Bridge as crews pour concrete on the newly-widened bridge deck. These overnight closures will either be northbound or southbound but not both directions at the same time. This work depends on dry weather, and schedules may change or shift on short notice.
Details of the first nighttime directional closure:
Overnight directional closure of I-205 northbound across the Abernethy Bridge (between OR 99E and OR 43) Saturday, June 20 from 11 p.m. to 7 a.m. This was originally scheduled for June 13, but postponed one week.
The following on-ramp will also close:
OR 43 on-ramp to I-205 northbound.
Local and Regional Detours
Northbound traffic will bypass I-205 in this section by using detours on I-5 and I-84.
Local traffic can use the Arch Bridge to cross the river.
Southbound I-205 lanes will remain open.
At this time, one more nighttime closure of I-205 northbound across the bridge is planned this month on June 27, but subject to change.
