Know before you go
If you plan to travel across Oregon in the coming days, make sure you carefully plan your route. I-84 and many other highways may be closed or unreliable due to wildfires.
Travelers are urged to use Tripcheck.com for up-to-date information. If traveling to recreation destinations in the gorge, check what's open before heading out.
Flaggers direct traffic at Multnomah Falls on the Historic Highway
 Looking up at the temporary work platform under the west viaduct. Railroad flaggers are used for safety when working around train tracks.
Repairs are occurring under the roadway on the west viaduct on the Historic Columbia River Highway at Multnomah Falls. In advance of a closure of the viaduct this fall, work is occurring under the structure.
While the west viaduct restoration is underway, travelers can expect:
- Nighttime single lane closures: intermittently through fall 2026.
- West viaduct closure: October 2024 to Memorial Day 2025.
