The George Abernethy Bridge,[4] or simply Abernethy Bridge,[1] is a steel plate and box girder bridge that spans the Willamette River between Oregon City and West Linn, Oregon, United States, and which carries Interstate 205. It is also known as the Oregon City Freeway Bridge and the I-205 Bridge.

The bridge was dedicated and opened on May 28, 1970, and cost $17.1 million to construct.[2] It is named for George Abernethy, who was the governor of the Provisional Government of the Oregon Country from 1845 to 1849 and later an Oregon City businessman.[1] An approximately $7 million seismic retrofit began in 2000 and was completed in 2002.[1] In 2008, the average traffic was 95,500 vehicles per day.[3]
