I-84: Graham Road Bridges

Project Completed

Region 1: Portland metro and Hood River County (Troutdale, Multnomah)

​​​​​​​ODOT has replaced the I-84 bridges over Graham Road in Troutdale, Oregon. The project raised the bridges to better accommodate truck traffic, constructed a third lane on Graham Road between the Frontage Roads, and increased safety and accessibility with a new sidewalk and bike lane on the east side of Graham Road.​​​​


Construction Impacts


  • Construction Start: February 2019 
  • Westbound I-84 Bridge Complete: Fall 2019
  • Eastbound I-84 Bridge Complete: Summer 2020
  • Graham Road Improvements Complete: Fall 2020
  • All Work Complete: End of 2020



Due to the poor condition of the bridge surfaces, this project replaced the bridges on Interstate 84 over Graham Road in Troutdale.

We constructed a third lane on Graham Road under the bridges and the height of the bridges was raised to better accommodate truck traffic. We built a sidewalk and bike path on the east side of Graham Road for pedestrians and cyclists.

What Problem Will This Improve?

  • The I-84 bridges over Graham Road were aging and due to be replaced. In particular, the westbound bridge surface showed severe deterioration in recent years.
  • The vertical clearance under the bridges was only 13.5', which is too short to safely accommodate the passage of large trucks and oversized vehicles.
  • Where Graham Road passed under I-84, there were narrow shoulders and no designated pedestrian sidewalks.
  • ​The two lanes on Graham Road under the bridges were not wide enough to accommodate the increase in northbound traffic, generated by new industrial development north of I-84.
