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

Design Phase

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

​Two 100 year-old elevated roadways that provide access to Multnomah Falls require repairs to continue providing access to one of Oregon's most iconic sites. The elevated roadways – called viaducts – carry vehicles and bicycles to the Falls and Lodge from the Historic Columbia River Highway. The repair work is slated to begin in fall 2024 and end in spring 2026.

Learn more about the viaducts and the repair.

From fall 2024 to spring 2026, expect full closures and delays on the Historic Highway near the Multnomah Falls Lodge. Access to the Falls and the Lodge will remain open. Be prepared to use I-84 for access and parking. There will be detours or lane closures for the Historic Highway. Or try transit with Columbia Area Transit to gain access.

One viaduct will be closed at a time between fall and spring each year. In between viaduct closures, there will be flaggers directing traffic on the Historic Highway. Over the next two years, you can expect: 

  • Nighttime single lane closures: intermittently from fall 2024 through fall 2026
  • West viaduct closure: fall 2024 through spring 2025
  • East viaduct closure: fall 2025 through spring 2026

West Viaduct Construction (fall 2024 to spring 2025)
Expect the following traffic impacts beginning fall 2024:

  • The Historic Highway will be closed just west of the Multnomah Falls Lodge. When the west viaduct is closed, there will be no access to Multnomah Falls by vehicles traveling eastbound on the Historic Highway. Vehicles traveling eastbound will be required to turnaround at the Wahkeena Falls Trailhead before reaching the Multnomah Falls Lodge and westbound vehicles will be required to turnaround at the Multnomah Falls Lodge. Each turnaround will be signed. Other sections of the Historic Highway will remain open during construction.

Take transit to Multnomah Falls when the viaducts are closed. Parking for Multnomah Falls will be available at I-84 Exit 31.  Visit or  to find more information about routes, schedules and tickets.

Construction will begin in fall 2024 and continue through spring 2026. Schedule subject to change.

Multnomah Falls on the Historic Columbia River Highway

Cost and Funding

​Funded through the Federal Lands Access Program


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.
