The East Multnomah Falls Viaduct on the Historic Columbia River Highway will now close for repairs starting October 6, 2025, after rain delayed the original closure date of October 1. The Oregon Department of Transportation announced that the viaduct will remain closed through spring 2026 to allow for significant repair work.
During this period, all traffic—including bicycles and vehicles—will be barred from the section of highway just east of Multnomah Creek near the employee parking area to the Oneonta Trailhead parking lot. Westbound vehicles from Hood River will have to turn around at the Oneonta Trailhead before reaching Multnomah Falls Lodge.
Access to Multnomah Falls via Interstate 84’s Exit 31 parking lot will remain available, but parking is limited. The west side of the historic highway will continue to provide access to the lodge parking lot, though travel further east on the highway will not be possible during construction.
To help ease congestion and avoid parking issues, public transit and private buses are recommended for visitors heading to Multnomah Falls Lodge. More information about routes, schedules, and tickets can be found at RideCatBus.org or ReadySetGorge.com.
The viaducts are listed as National Historic Landmarks. The Oregon Department of Transportation stated: “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.” In May 2025, repairs were completed ahead of schedule on the west viaduct after its closure in fall 2024.
Repair work on these structures includes removing old asphalt and installing a new concrete surface that matches the original appearance from 1914. Additional work involves repairing railings, columns, and support beams with cracks or exposed rebar to improve stability and address erosion. Permanent signs along the route will also be replaced to meet current standards.
According to ODOT, about 4,000 vehicles use these viaducts daily. Preserving their unique railings and stone support walls is part of maintaining their historical significance so they continue serving travelers along this scenic route for years ahead.
