Multnomah Falls Viaducts Repair

Design Phase

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

​Two historic viaducts carry traffic on the Historic Columbia River Highway on either side of Multnomah Falls. The viaducts are aging and need repairs. 

Columbia River Gorge Construction: I-84 and U.S. 30 Historic Columbia River Highway


Construction Impacts

​This work will require closures of one viaduct at a time between fall and spring each year and lane closures on the Historic Highway with flaggers directing traffic.


​Construction occurs between fall 2022 and summer 2025.

​These repairs will allow the viaducts to continue to carry traffic along the Historic Highway for years to come.  

Additional Information

​​The Columbia River Gorge is one of Oregon’s seven wonders – home to the first highway in the Pacific Northwest, sweeping vistas and rich history. And for more than 100 years, it’s been an important corridor for freight movements, both in the water and on the road.

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

Each project brings benefits to residents, businesses and visitors by increasing safety, extending the lifespan of the highways or completing a gap in walking and biking infrastructure.
