Project-Details

Multnomah Falls Viaducts

Design Phase

Region 1: Portland metro and Hood River County (Multnomah)

Two historic viaducts carry traffic on the Historic Columbia River Highway to Multnomah Falls. The viaducts are over 100 years old and repairs will allow the viaducts to continue carrying traffic along Historic Columbia River Highway for years to come.

A viaduct is an elevated roadway supported by columns, piers or arches.

Impacts

Traffic Impact

There will be lane closures and full closures of the viaducts. This work will close one viaduct at a time between fall and spring each year (2024 to 2026). Flaggers will help direct traffic on the Historic Columbia River Highway.

West viaduct closure: fall 2024 through spring 2025
Daily single-lane closures: intermittently from spring 2025 through fall 2026
East Viaduct closure: fall 2025 through spring 2026

The schedule is subject to change. You can sign up for our newsletter to learn more about current traffic impacts on the project webpage at http://i84GorgeConstruction.org/.
