Project-Details

Multnomah Falls Viaducts (Historic Columbia River Highway/U.S. 30)

Construction Phase

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

Two 100 year-old elevated roadways at Multnomah Falls need repairs to continue providing access. The elevated roadways – called viaducts – carry vehicles and bicycles to the iconic Multnomah Falls and the Multnomah Falls Lodge along the Historic Columbia River Highway.

Impacts

Traffic Impact

Construction Impacts

West viaduct: The west viaduct has reopened to all traffic, including bicycles and vehicles. The viaduct remains closed to pedestrians. Visitors can use the Historic Columbia River Highway to access Multnomah Falls from the west side of the lodge.

During summer 2025, travelers accessing the west viaduct can expect periodic single lane closures with flaggers directing traffic while crews clean up the site and put finishing touches on the railings. One lane of traffic will remain open to vehicles and bicyclists.

East viaduct: Periodic nighttime lane closures with flaggers directing traffic.

The east viaduct will close to all traffic, including bicycles and vehicles, from fall 2025 to spring 2026. During the closure, vehicles traveling westbound from Hood River will be turned around at the Oneonta Trailhead before reaching the Multnomah Falls Lodge. Other sections of the Historic Columbia River Highway will remain open during construction.

Cost and Funding

$23.7 million funded through the Federal Lands Access Program

Benefits

The viaducts are National Historic Landmarks and we will preserve their historic integrity to retain the look they had in 1914. Their features will be similar to the old design in color and texture. These repairs will allow each viaduct to continue carrying traffic along the Historic Columbia River Highway for years to come.

Additional Information

Over the next several years, we have many construction projects planned on I-84 between I-205 and Hood River, and on the Historic Columbia River Highway between Troutdale and Hood River.
