Regional construction impacts

Construction noise in West Linn

Crews are intermittently doing demolition work in West Linn on the north and south side of I-205. On the south side, crews are working to remove 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 are also removing the columns below the I-205 southbound off-ramp to OR 43 on the north side. 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.

OR 43 overnight closures under the Abernethy Bridge the nights of Sept. 16, 17, 22, 23

Expect overnight closures of OR 43 in West Linn in both directions under the I-205 Abernethy Bridge on Wednesday, Sept. 16, Thursday, Sept. 17, Tuesday, Sept. 22 and Wednesday, Sept. 23 from 10 p.m. to 5 a.m. each night.

During the overnight closure of OR 43, the northbound on-ramp to I-205 from OR 43 will also close.

Expect increased congestion in West Linn near I-205 during the nighttime work.

There will be noise associated with this nighttime work as the contractor will also be doing some demolition work during the overnight closures.

Detours

Drivers will be detoured onto I-205 in order to bypass the closure.

People walking and bicycling will experience short holds and flagging on OR 43 during the overnight closures but will be able to travel through with delays.

OR 99E off-ramp from I-205 north closed the night of Sept. 27 until the morning of Oct. 2.

Beginning at 10 p.m. on Sunday, Sept. 27 until 5 a.m. on Friday, Oct. 2, the OR 99E off-ramp from I-205 north will close around-the clock. The closure is needed for crews to rebuild the off-ramp so it will align with I-205 in the next stage of construction. The off-ramp will be closed to all traffic, including emergency services, for the duration of the closure.

During the ramp closure, there will be a signed detour directing drivers to continue north on I-205 to exit 11 (82nd Drive). From there, drivers can return to I-205 heading south and exit at OR 99E.

This work is weather-dependent and may have a delayed start due to wet conditions. Please check here for ongoing updates.
