I-205 George Abernethy Bridge Preservation Project

Project Information
Oregon Department of Transportation started work July 2009 on a $6.9 million preservation project on the I-205 Abernethy Bridge over the Willamette River, linking Oregon City and West Linn.  Over 100,000 vehicles cross this bridge each day. 
The project will repair bridge joints and repave the bridge structure that carries I-205 traffic across the Willamette River. Work includes replacing the bridge expansion joints and repaving the bridge. It is being done by Wildish Construction of Eugene, Oregon. 

The project will require approximately 10 weeks of night work and intermittent weekend closures of the Abernethy Bridge off- and on-ramps (Exit 8).  The paving work will start in August and will take about 3 weeks.  The majority of the joint work will occur in September.  The project is expected to be completed in late fall 2009.

Traffic Impacts
The high traffic volumes on I-205 require that all lanes be open without restrictions during daytime hours.  Closing the lanes during the day would create backup and serious safety concerns.  As a result, most work will take place during nighttime work hours from 8 p.m. to 5 a.m. when traffic volumes are lower.  Motorists can expect multiple lane closures and on and off-ramp closures along the Abernethy Bridge.  The contractor will work in one direction at a time. 
ODOT determined that the work on the Abernethy Bridge should precede the 24-month closure of the OR 43 Willamette River Bridge (the historic arch bridge linking Oregon City and West Linn) for rehabilitation.  The I-205 Bridge is the designated detour route during the arch bridge rehabilitation project.  Look here for the OR 43: Willamette River Bridge Rehabilitation Project web site.

During ramp closures on Exit 8, detoured traffic will be sent to the 10th Street interchange (Exit 6) and the Gladstone interchange (Exit 11).
Motorists should be alert to enhanced police traffic patrols in the I-205 Abernethy Bridge work area. 
Nighttime Noise
Nighttime construction noise may be audible to residents living along the project corridor.  It is ODOT’s intention to keep those nearest the work notified of nighttime, noise-generating activities.  A noise hot line phone number, 503-771-3370, is available for reporting noise problems or incidents requiring immediate attention.
