Construction Impacts

Nov. 19, 2021 update: 

Crews plan to use rock blasting and rolling slowdowns once next week, on Wednesday, Nov. 24 between 9 and 11 a.m.

For safety, when rock blasting near the face of the rock slope, rolling slowdowns in both directions of I-84 will be used to create 20-minute windows where there is no traffic.

Travelers should plan ahead, especially for early holiday travel. Any associated backups or delays from rolling slowdowns are expected to be clear prior to noon Wednesday. Check for real-time traffic updates. 

Rolling slowdowns between Cascade Locks and Memaloose State Park (east of Mosier) are typically scheduled to occur on Tuesday and Thursday mornings between 9-11 a.m. 

The schedule is shifting next week to allow time for crews to assess the next section of rock with probes as the tunnel continues deeper into the rock face. This additional geotechnical work will help inform how best to continue with rock excavation and blasting. ​


Beginning Tuesday, Oct. 12 travelers on Interstate 84 between Cascade Locks and Memaloose State Park (east of Mosier) should plan for long delays Tuesday and Thursday mornings. 

​During rock blasting, rolling slowdowns in both directions of I-84 will be used to create 20-minute windows where there is no traffic.

Rolling slowdowns are typically scheduled to occur on Tuesday and Thursday mornings between 9-11 a.m. We estimate about eight days of rolling slowdowns are needed for this work. The schedule is subject to change. ​

Travelers should plan for long delays or travel at an alternate time if possible.

What to expect during construction:​

  • Travelers should plan for single lane or shoulder closures on I-84 east from Monday mornings through Friday morning. 
  • Exit 58 off-ramps will be closed throughout construction. 
  • Beginning summer/fall 2021, constructing the new tunnel will require the contractor to use rock blasting, where experts use a carefully calculated amount of explosives to remove rock in a controlled manner. During rock blasting, traffic on Interstate 84 will experience rolling slowdowns and delays.  Whenever possible, we will post schedule updates and send out project emails.​
  • Most traffic impacts will occur weekdays.

Key Milestones

  • May 16, 2018: Open House
  • May 21, 2018: The Advisory Committee recommended a design alternative for the Mitchell Point Crossing.
  • June 13, 2018: The Oregon Parks and Recreation Commission endorsed the design recommendation.
  • Through 2020: Design continued on the preferred alternative, which includes a Columbia River Gorge National Scenic Area permit. 
  • Spring 2021: Construction begins


​Constuction began in spring 2021 and is expected to take about two years to complete. 



Mitchell Point was the site of an iconic tunnel with its five arched windows overlooking the Columbia River. Constructed in 1915, the tunnel was closed in 1953 because it could no longer accommodate high traffic volumes and car sizes. It was destroyed in 1966 to widen the water-level highway, now Interstate 84. The historic tunnel was 390-feet long.

Mitchell Point is a formidable mountain that requires a new crossing to connect the western segments of State Trail to Hood River and The Dalles. ODOT received funds for design and construction of a new Mitchell Point Crossing from the Federal Lands Access Program​, a competitive nationwide grant for projects improving access to federal lands. 

At the May 16, 2018 open house, three alternative crossing designs were presented, including two tunnel options. 

On May 21, 2018 the Historic Columbia River Highway Advisory Committee recommended the 570-foot tunnel and trail alternative and on June 13, 2018 the Oregon State Parks and Recreation Commission endorsed the same design recommendation. 

The final tunnel plans include five arched window and a 655-foot tunnel.

Western Federal Lands Highway Division is the contract administrator for this construction project. ODOT owns and operates the Historic Highway. Oregon Parks and Recreation Department manages the State Trail in partnership with ODOT.​

Additional Information

​The Columbia River Gorge is one of Oregon’s seven wonders – home to the first highway in the Pacific Northwest, sweeping vistas and rich history. And for more than 100 years, it’s been an important corridor for freight movements, both in the water and on the road.

Over the next several years, we have many construction projects planned on Interstate 84 between Interstate 205 and Hood River, and on the Historic Columbia River Highway between Troutdale and Hood River. 

Each project brings benefits to residents, businesses and visitors by increasing safety, extending the lifespan of the highways or completing a gap in walking and biking infrastructure.
