Key Milestones

  • 2024: Mitchell Point Tunnel expected to open
  • 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


Construction began in spring 2021. The tunnel is expected to open in 2024.



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.​
