(Multnomah Falls, OR) -- The Historic Columbia River Highway reopened Friday, following a two-year restoration project. Work on the East Multnomah Falls Viaduct lasted seven months and is the second of two phases to restore 100-year-old elevated sections of the highway also known as U.S. 30. ODOT patched original decorative concrete, reinforced structural stability and poured a new road surface. This summer, drivers should still expect flaggers in the area, as crews clean up the site and complete finishing touches on the railings and pavement striping.
