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.

Watch a video about the repair project.

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.
