OREGON CITY – Overnight demolition work resumed this week and will last into the next as progress continues on the I-205 Abernethy Bridge Project. The current deck demolition is scheduled from Monday, April 7 to Saturday, April 12 and again from Monday, April 14 to Friday, April 18. Work will last from 9:30 p.m. until 4:30 a.m. each night.
For the next two weeks work will focus on removing portions of the existing bridge deck in preparation for the eventual widening of the structure.
-
What is being removed? Sections of the concrete barrier and concrete deck surface over OR 99E along northbound and southbound I-205 in preparation for girder removal.
-
Why is the demolition being done now and where does it fit in the project? In order to install new steel girders and fittings to handle the upcoming widening on the Abernethy Bridge, some sections of the existing bridge deck need to be removed to make room for the new sections.
-
Why is demolition work happening at night? Night work is needed since some demolition will occur directly above OR 99E and other areas with active vehicle and pedestrian foot traffic during the day. These areas need to be closed for safety purposes, and we do this when traffic volumes are low.
-
What are the next steps? Demolition work will continue through May. Some demolition work will occur during the daytime, when it can be done safely.

We know the noise from construction work can be disruptive. We appreciate your patience as our crews work tirelessly to complete the first earthquake-ready interstate bridge across the Willamette River in the Portland metropolitan area.
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.
Traffic Impacts
In addition to the demolition work, there are multiple lane reductions and ramp closures occurring this week throughout the project area. Full details can be found on the project website.
As with any construction project, closure dates and timing are subject to change. The latest information on traffic impacts will be available at TripCheck.com.
