Work progresses for viaduct construction west of Multnomah Falls
 Recently installed rebar to support the future concrete surface on the west viaduct near Multnomah Falls.
Crews continue work on and under the Historic Columbia River Highway at the Multnomah Falls west viaduct. We removed the old asphalt from the surface of the viaduct and installed new rebar. When weather allows, crews will pour a new, concrete surface. The work will restore its original color and features before re-opening to traffic by Memorial Day 2025.
Travelers near Multnomah Falls can expect:
- The West viaduct to remain closed to all traffic, including bicycles and vehicles. The Wahkeena-Multnomah Falls return trail #442 remains open to hikers.
- Public transit and private buses are still available to take you to Multnomah Falls. Visit RideCatBus.org or ReadySetGOrge.com to find more information about routes, schedules and tickets.
- Access to Multnomah Falls via the I-84 parking lot at Exit 31 remains open, but available parking spaces may be limited.
Learn more about the viaduct repairs by watching this video.
Work is also continuing underneath the east viaduct without impacting traffic as crews prepare to close access east of Multnomah Falls in fall 2025 for similar repairs.
Bridal Veil bridge repairs are underway
 Crews work from a suspended platform underneath the Bridal Veil bridge.
Repairs to the Bridal Veil bridge are underway through spring 2025. Crews built a work platform under the bridge allowing them to access and make repairs to the bottom of the structure. Over the next few months, crews will be repairing the concrete and patching exposed rebar. A layer of coating will then be applied to the bridge railings and columns to help blend the appearance of new and old concrete. The bridge will be allowed to age naturally, providing the natural Gorge aesthetic people know and love.
Travelers on the Historic Highway can expect:
- One lane on the bridge to remain open with flaggers directing traffic. Expect delays of up to 20 minutes.
I-84 east McCord Creek Bridge Replacement pre-construction work begins
 Crews prepare the work site under the McCord Creek bridge.
Construction has begun to replace the aging bridge that carries eastbound I-84 over McCord Creek near Warrendale. Replacing the bridge will eliminate a dip in the road and increase safety, earthquake resilience and the lifespan of the highway. Crews recently started pre-construction activities under the bridge which includes placing erosion control around the work site and building a temporary access road near the highway.
Travelers on I-84 can expect:
- Periodic nighttime single lane closures on I-84 through fall 2025.
- Shoulder closures around-the-clock.
From Fall 2025 through 2026, impacts to I-84 and the Historic Highway State Trail will include:
- I-84 reduced to one lane in each direction where eastbound traffic will share the westbound bridge.
- I-84 will be closed at the bridge for several days where traffic will detour using U.S. 26. Detour information will be shared in advance of the closure.
- A two-month closure of the State Trail where shuttle service will provide access for users between John B. Yeon and Toothrock Trailheads to avoid construction.
 We will share more information in advance of these traffic impacts. Visit tripcheck.com or call 5-1-1 for traffic alerts. You can also sign up for our Region 1 newsletter to stay up to date.
ADA curb ramp upgrades continue in Hood River
We are improving safety and access for all by upgrading sidewalk curb ramps to current Americans with Disabilities Act (ADA) standards on U.S. 30 at Cascade Avenue and Oak Street in Hood River. We are also upgrading sidewalk corners from Mt. Adams Avenue to E 2nd Street and adding new ramps at some corners.
Travelers in Hood River can expect:
- Periodic lane closures with flaggers directing traffic on U.S. 30, short term closures of side streets and temporary parking space closures.
- Accessible paths around the work zones are available for people walking, biking and rolling.
Crews continue to monitor the Historic Columbia River Highway at Larch Mountain Road
 ODOT crews assess the site for landslide activity.
Earlier this month, we closed a section of the Historic Columbia River Highway between Portland Women’s Forum and Vista House due to the road settling east of the split with Larch Mountain Road. Since then, we have temporarily reopened the road.
This section of the Historic Columbia River Highway sits on an ancient landslide and has a history of landslide activity. We have monitored this area closely for decades. After evaluating recent land movement, we sealed the cracking on the road and placed orange construction barrels on the existing guardrail for improved visibility of the work area.
Our crews continue to monitor the slope daily and will keep the road open if it appears safe for traffic. Plans are underway to develop long-term repairs.
What to expect in this area:
- If significant landslide activity occurs while monitoring, we may need to close the road to all users to keep travelers safe.
- When the ground dries this summer, we will begin long-term repairs which will require closures in this area.
- Temporary lane or full closures.
- Use caution in the area.
 Historic Columbia River Highway reopen at Larch Mountain Road.
Please check TripCheck.com before you use this route as work continues in this slide area.
Please also note that the Historic Highway remains closed just west of Multnomah Falls for structural repair work on the Multnomah Falls Viaduct project. We expect to reopen this area for the summer tourist season.
More information on work scheduled in the coming months and beyond is available on our project website. Stay tuned for more email updates!
