Willamette River users will be the first to notice work on a $10.6 million rehabilitation of the historic Oregon City / West Linn Arch Bridge, which begins next week. Barges will move up the Willamette River and be installed Tuesday at the base of the 88-year-old bridge. The barges, used as work platforms and also to prevent material from impending bridge work from going into the river, are anchored by cable attached to each shore. With barges in place, the river channel will shrink to 120 feet wide, requiring boaters to use additional caution as they move through the area.
