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.

The next overnight directional closures of I-205 southbound are planned for July 31 and August 1.

The I-205 Abernethy Bridge is in the midst of a series of overnight directional closures this summer as crews pour concrete on the newly-widened bridge deck. These closures 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 overnight closures of I-205 across the bridge are in the southbound direction and are currently planned for Friday, July 31 and Saturday, August 1.

Details of the July 31 and August 1 nighttime directional closures:

  • Overnight directional closures of I-205 southbound across the Abernethy Bridge (between OR 99E and OR 43) Friday, July 31, and Saturday, August 1, from 11 p.m. to 7 a.m. both nights 

  • The following on-ramp will also close both nights:

    • OR 99E on-ramp to I-205 southbound from 10 p.m. to 8 a.m.

Local and Regional Detours

  • Southbound traffic can bypass I-205 in this section by using detours on I-5, I-84 and the Ross Island Bridge.

  • Local traffic can use the Arch Bridge to cross the river.

  • Northbound I-205 lanes will remain open.

Additional overnight closures on I-205 south are planned on Friday, August 7, Saturday, August 8, Friday, August 14, and Saturday, August 15. Southbound overnight closures will continue in August.
