One lane in each direction of I-84 near Exit 35 in Warrendale remains closed between Ainsworth State Park and Bonneville Dam as both directions of traffic share the westbound bridge over McCord Creek until late summer 2026. Crews recently removed the aging eastbound bridge, constructed the new bridge’s foundations and will begin installing large steel beams (girders) for the new bridge support. Replacing the eastbound bridge will eliminate a “dip” in the road and increase safety, earthquake resilience and the lifespan of the highway.
The Historic Columbia River Highway State Trail also remains closed near McCord Creek through early summer while cranes are temporarily staged on the trail to set the steel beams. For your safety, the trail must remain closed until those beams are installed and the heavy crane is moved out of the way.
Temporary shuttle service is available for trail users between John B. Yeon and Toothrock Trailheads until the trail reopens. Details about the shuttle and trail closure are available on this handout or the project website – please share with your friends and fellow trail users!

ADA-accessible shuttle parked at John B. Yeon Trailhead provides temporary service for trail users during construction. View the handout linked in the section above for shuttle schedule, pickup and drop-off locations.
Travelers on I-84 can expect:
- Eastbound traffic to share the westbound bridge with one lane open in each direction through late summer 2026.
- Intermittent single lane and shoulder closures on I-84 eastbound and westbound until fall 2026.
- The NE Frontage Road on-ramp to eastbound I-84 at the Elowah Falls Trailhead parking lot remains closed during construction. Travelers accessing eastbound I-84 from NE Frontage Road must detour to the on-ramps at Ainsworth State Park (exit 35).
Historic Columbia River Highway State Trail users can expect:
- The Historic Highway State Trail to remain closed through early summer 2026 with shuttle service between John B. Yeon and Toothrock Trailheads. Details about the shuttle are available on the project website.

We are excited to announce that the Historic Columbia River Highway (U.S. 30) has reopened east of Multnomah Falls! This concludes the last of two significant closures in our two-year project to repair two 100 year-old elevated roads east and west of Multnomah Falls. Finishing the work marks a significant milestone toward restoring and extending the service life of the original “King of Roads” through the Columbia River Gorge from Troutdale to The Dalles. Visitors will be able to see the viaducts on their next trips through the Gorge on the Historic Columbia River Highway.
Over the summer, travelers using the east viaduct can expect to see flaggers directing traffic while crews clean up the site, complete finishing touches on the railings and install permanent striping.
Since work began on the east viaduct in October 2025, crews patched the original decorative concrete, reinforced the structural stability of the aging structure and poured a new road surface. The repair work ensures the structure continues carrying traffic near Multnomah Falls for years to come while preserving the historic integrity so the viaducts, with their unique railings and stone support walls, look similar to when they were built in 1914.
In May 2025, we opened the west viaduct between Wahkeena Falls and Multnomah Falls after finishing similar restoration work.
Both closures allowed crews to repair the viaducts, which are elevated roadways contributing to the Historic Columbia River Highway’s National Historic Landmark status. The repair work ensured their preservation and increased the amount of weight they can support.
The Historic Columbia River Highway viaducts, east and west of Multnomah Falls, are open to vehicles less than 35 feet long and bicycle travel only. Both are closed to pedestrians because the highway is too narrow.
Thank you for your patience while crews restored and rehabilitated the historic viaducts.
The viaduct east of Multnomah Falls Lodge has reopened to vehicles and bicyclists.

How to access Multnomah Falls
- Visitors to the waterfall corridor, Multnomah Falls Lodge, and nearby trails can now access these sites from the Historic Columbia River Highway (U.S. 30) from both directions of Multnomah Falls Lodge.
- A Timed Use Permit will be required for visitors using the I-84 (Exit 31) Multnomah Falls parking lot between 9 a.m. and 6 p.m. from May 22 through Sept. 7, 2026. Information about the permits is available at https://www.recreation.gov/timed-entry/10089144.
- Visitors are encouraged to take transit to avoid parking delays. The Gorge has multiple public and private bus options to reach areas like Multnomah Falls. Visit RideCATbus.org or ReadySetGOrge.com to find more information about routes, schedules and tickets.
- Drivers to Multnomah Falls may park in the lot at Exit 31 from I-84 or the smaller parking area on the Historic Columbia River Highway (U.S. 30). Real-time traffic impacts and cameras showing parking availability at the Exit 31 lot are available at TripCheck.com.
About the restoration work
About 4,000 vehicles use the viaducts daily. The structures are original to the Historic Highway and listed as a National Historic Landmark. The repair work preserved the historic integrity so the viaducts, with their unique railings and stone support walls, look like they did when they were originally built in 1914.
The viaduct repairs included:
- Removing the aging asphalt and installing a new concrete surface to match the original 1914 design in color and texture.
- Repairing concrete railings, vertical columns, and horizontal support beams under the viaduct -- which had cracks and exposed rebar -- to improve stability and address erosion.
- Replacing permanent signs to meet current standards.

Work is progressing to close the 0.7 mile gap on the Historic Highway State Trail between Viento State Park and Mitchell Point.
Crews have formed the base of the future trail and installed rebar on the surface of the Perham Creek Bridge. Next, crews will begin pouring the concrete bridge surface. Once this segment is complete in late 2026, the State Trail will provide nearly 10 miles of continuous car-free ADA-accessible trail for people walking, biking and rolling in the Columbia River Gorge between Wyeth State Park and the Mitchell Point Tunnel.
While work is underway, the temporary pedestrian-only trail is closed. View this handout to learn more – please share with your friends!

We’re building a new multiuse path along Jordan Road near the Sandy River Delta. The path will connect to the existing pedestrian and bicycle tunnel underneath I-84 with the Sandy River Delta recreational area, also known as Thousand Acres Park.
Crews have been preparing the work site, including clearing vegetation and have started laying the groundwork and materials to start building the new retaining wall and future multiuse path along Jordan Road.
Construction continues through late summer 2026.
View of crews hauling out rock and pushing material down to grade for both the future retaining wall and the multiuse path parallel to Jordan Road near I-84 at Exit 18.
During construction, travelers, including pedestrians and bicyclists can expect:
- No traffic impacts to I-84.
- Periodic single lane closures on Jordan Road north of I-84, with flaggers directing traffic as needed; expect some delays at the westbound I-84 exit ramp while flaggers are present.
- The pedestrian and bicycle tunnel underneath I-84 will remain open during Phase 1 construction on the path but will temporarily close during Phase 2. Watch for signage.
- Existing trails will remain open during construction.
- The parking lot for the Sandy River Delta recreational area will remain open.
Work continues to improve safety and visibility at multiple on and off-ramps on I-84 between downtown Portland and Hood River by installing or replacing lights and signs, and trimming overgrown vegetation as part of our All Roads Transportation Safety (ARTS) program.
Crews have been removing existing signs with new ones at several locations and installing underground electrical wiring in preparation for signal upgrades.
Construction continues until fall 2026.

The U.S. Forest Service is reinstating its seasonal Multnomah Falls (I-84) Timed Use Permit system for I-84 Exit 31. Between May 22 and Sept. 7, 2026, from 9 a.m. to 6 p.m., a Multnomah Falls (I-84) Timed Use Permit is required for each personal vehicle accessing Multnomah Falls from Exit 31. Permits must be obtained in advance to park at the lot on the Interstate at Exit 31.
A limited number of permits will be available for same-day pickup without a transaction fee at the Gateway to the Gorge Visitor Center in Troutdale and the Cascade Locks Historical Museum.
The Historic Columbia River Highway reopened between Larch Mountain Road and Vista House on March 17 after a landslide closed the route.
Repairs to the concrete stone wall and additional work below the road will take place in the coming months. Travelers should expect flaggers and intermittent traffic control in the area when that work begins. We will share an update once that work is scheduled.
Travelers can access Vista House and the Portland Women’s Forum from both directions. Drivers should continue to use caution in the area and watch for any remaining debris.
Road work schedules can change due to weather, so please visit Tripcheck.com for the latest information on road conditions before you travel.

The Historic Columbia River Highway State Trail is closed between the Eagle Creek Trailhead and Cascade Locks due to a Dec. 19 landslide that occurred after heavy rain. The landslide left large boulders, trees and deep mud covering the trail, making it unsafe to use. Visitors are strongly discouraged from trying to get around this section. There is no alternate route for hiking or biking this section of the trail.
We are working to secure funding for repairs and will share updates when we have a clearer timeline.
For information about the trail and trailheads accessible along the way, visit the Oregon State Parks web page.
Work to clean and repair several culverts under I-84 between the Sandy River and Multnomah Falls is now complete.
Culverts are pipes built beneath a highway or road to allow stormwater, streams and rivers to flow under the road surface to the other side and prevent flooding and erosion. These repairs improved safety by managing stormwater and extended the life of the highway.
