Interstate 205 at the Willamette River
George Abernethy Memorial Bridge on August 19, 2006
George Abernethy arrived in Oregon on June 2, 1840 as part of Jason Lee's Methodist Willamette Mission at Champoeg. He was involved in the series of meetings to form the Oregon Country's provisional government, and became the first provisional Governor in 1845. Abernethy served two terms as Governor, until 1849, when Oregon became a territory of the United States and the provisional government ceased to exist. Abernethy's home was located on the east bank on the Willamette River near Oregon City.

This steel plate and box girder bridge opened on May 3, 1970 carrying Interstate 205's 6 lanes across the Willamette River. It was built near the location of Abernethy's home. The bridge is made up of 15 spans and 60 girders. The bridge is 2,727 feet long. The longest span is 430 feet long, and maximum vertical clearance at low river level is 85 feet. The entire bridge is built on a slope such that southbound traffic is going uphill for the entire length of the bridge and for a half-mile beyond. The bridge was built at a cost of $15.9 million, and an $8 million seismic retrofit was done from 1999 to 2002. The bridge was designated the "George Abernethy Memorial Bridge" by the 1979 Oregon Legislature.
