As work continues to improve the I-205 Abernethy Bridge, crews will install permanent supports (cantilever brackets) for the planned bridge widening. These structural components are anchored to the bridge and will help support the weight of the new, wider bridge surface (shown in the picture below). To safely complete this work, nighttime lane and ramp closures are planned throughout August.
Upcoming Nighttime Lane and Ramp Closures
Construction work on and around I-205 will result in several nighttime lane and ramp closures the week of August 11.
- Nighttime ramp closure from OR 43 to I-205 northbound from Monday, August 11 to Saturday, August 16 from 10 p.m. to 5 a.m.
- Nighttime ramp closure from I-205 northbound to OR 99E (exit 9) from Monday, August 11 to Saturday, August 16 from 10 p.m. to 5 a.m.
- Nighttime lane closures on I-205 northbound from Monday, August 11 to Saturday, August 16 from 10 p.m. to 5 a.m.
- Lane closure on OR 43 and OR 99E at I-205.
- Pedestrian detours on OR 43 and OR 99E.
These closures are planned throughout the month and will also occur during the weeks of August 18 and August 25.
Details and detour maps can be found on the project website or Tripcheck.com. As with any construction project, closure dates and timing are subject to change.

Demolition Work on Bridge Piers Continues
We know the noise from construction work can be disruptive, and we appreciate your patience. Demolition of one of the bridge piers on the West Linn side of the river is underway as part of the upcoming bridge widening project. Work is taking place from 2 p.m. to 10 p.m. on weekdays, with occasional Saturdays, and is expected to continue for the next several weeks.
Residents in the vicinity of the construction area should anticipate elevated noise levels while this work is occurring. A 24/7 nighttime noise hotline is available at 503-276-7809.

What is this project?
ODOT is upgrading the Abernethy Bridge, which spans the Willamette River between Oregon City and West Linn, to withstand a major earthquake. Additional improvements are being made to the bridge's adjacent on- and off-ramps to improve safety. This work is expected to be completed in 2026.
