Nighttime I-205 Closures to Affect Oregon City, West Linn During Abernethy Bridge Work
Nighttime closures on I-205 between Oregon City and West Linn are underway as part of the Abernethy Bridge seismic upgrade and widening project. These closures include alternating northbound and southbound lanes, as well as additional ramp and lane closures on OR 99E and OR 43. Construction activities involve bridge deck demolition and waterline excavation, with the project expected to be completed in 2026.
According to Oregon Live, drivers in the Oregon City and West Linn area should expect nighttime lane closures, detours and construction noise as work continues on the Abernethy Bridge, part of the Oregon Department of Transportation’s largest construction project in nearly 50 years.
The project will make the Abernethy Bridge the first earthquake-ready interstate bridge across the Willamette River in the Portland area. Upgrades include seismic reinforcement, new on-ramps and off-ramps, interchange improvements at Oregon 43 and Oregon 99E, bike and pedestrian upgrades, and construction of a sound wall near the southbound I-205 Exit 9.
