Saturday, local leaders presided over the re-opening of Clackamas County’s Arch Bridge.
Spanning the Willamette between Oregon City and West Linn, the Arch Bridge opened in 1922. Designed by the man behind many Oregon Coastal icons, Conde McCullough, it’s been closed for the past 22 months as Oregon’s Department of Transportation made extensive repairs – structural and cosmetic. ODOT’s Don Hamilton explained the bridge needed a lot of work.
Hamilton said, “We tried very hard to preserve the appearance of the bridge. But the details of that were much more complicated. The bridge had had its weight load capacity reduced in recent years. We had to restore that. And we had to bring it up to safety standards, strong guardrails, better lighting, and give it some seismic installations.”
Hamilton says the concrete was in bad shape. Crews had to install steel cables in the main concrete railings. The project cost $15 million, most of which was provided by the federal government.
