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.

June 27 overnight directional closures of I-205 northbound is complete. The next one is planned for July 10

The I-205 Abernethy Bridge is fully open between OR 99E and OR 43 after last night's (Saturday, June 27) closure in the northbound direction for crews to pour concrete on the newly-widened bridge deck

This was the first in a series of overnight directional closures of the I-205 Abernethy Bridge this summer as crews continue pouring concrete on the bridge deck. These will either be northbound or southbound but not both directions at the same time. This work depends on dry weather and necessary prep work, and schedules may change or shift on short notice.

The next two overnight closures of I-205 northbound across the bridge are currently planned for Friday, July 10 and Saturday, July 18.

Details of the July 10 nighttime directional closure:

  • Overnight directional closure of I-205 northbound across the Abernethy Bridge (between OR 99E and OR 43) Friday, July 10, from 11 p.m. to 7 a.m. 

  • 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.

An additional nighttime closures of I-205 northbound across the bridge is planned on July 18.
