Travelers should plan for continued construction while we improve the highway this summer
Construction continues for multiple projects in the Columbia River Gorge between Multnomah Falls and Hood River to improve Interstate 84 and extend the Historic Columbia River Highway State Trail.
Each project brings benefits to residents, businesses and visitors by increasing safety, extending the lifespan of the highways or completing a gap in pedestrian and biking infrastructure.
Travelers should pack their patience and plan ahead. This summer, you can plan for the majority of traffic impacts to occur during the week, minimizing weekend impacts when traffic volumes are higher. Construction schedules are often weather dependent and subject to change. Check TripCheck.com for real-time information.

Mitchell Point Tunnel
 Crews are lining the Mitchell Point Tunnel with structural shotcrete, which is concrete containing steel fibers and sprayed into place. Next, crews will add another coat of shotcrete tinted to mimic the color of the natural rock.

I-84 east, Exit 58: Closed around-the-clock to extend the Historic Columbia Highway State Trail and construct the Mitchell Point Tunnel.
-
I-84, Multnomah Falls to Cascade Locks: Periodic nighttime single lane closure from 7 p.m. to 7 a.m. This summer, lanes in the area will be narrowed and speed limits are reduced while crews repave 13 miles of highway and repair several bridges, and the Toothrock Tunnel.
- The I-84 Culvert Repair project will repair more than a dozen culverts this summer to extend their lifespan and maintain safety on the highway. The new culvert linings will be cured-in-place beneath the highway to avoid roadway excavation and minimize travel delays to your trip. When work begins, travelers on I-84 can expect:
- Nighttime lane closures between Corbett and Multnomah Falls.
- Nighttime closures of the Exit 22 westbound on-ramp to I-84 and the I-84 west off-ramp to the Corbett Viewpoint.
