Project Details

I-84: Graham Road Bridges Replacement

Design Phase

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

ODOT is starting design work for a project to replace the I-84 bridges over Graham Road in Troutdale, Oregon. The project will raise the bridges to better accommodate truck traffic, widen Graham Road from two lanes to three between the Frontage Roads, and add a sidewalk and bike lane on the east side of Graham Road to provide safer access and improved connections for people who walk or ride bikes.


Construction Impacts

Replacing the bridges and widening Graham Road will require closures and detours that will impact vehicles and pedestrians. ODOT will work with travelers and adjacent businesses to provide advance notice about detours and maintain business access during construction.

Pedestrians and Bus Users

  • Pedestrian access on Graham Road may be temporarily closed to allow removal and construction of the new bridges and sidewalk. Pedestrians who need to travel through the project area will be accommodated during closures and construction.
  • ODOT will work with TriMet to notify the public if bus stop changes are required.

Drivers, Bike Riders, and Freight Traffic

  • There will be daytime and nighttime single-lane closures on Graham Road between South Frontage Road and North Frontage Road. Graham Road under I-84 will also need to be fully closed during some phases of bridge removal and reconstruction.
  • South Frontage Road will require single-lane daytime and nighttime closures of the north far left lane while Graham Road is closed. At these times travelers will still have access to businesses on the south side of South Frontage Road. There will also be other occasional nighttime single-lane closures on South Frontage Road, not related to Graham Road closures.
  • I-84 travelers may experience closures and related slow-downs, and lane shifts.
  • Work on the I-84 entrance and exit ramps at Graham Road will require nighttime closures.

Sign Up for Updates

An update about road closures and other traffic impacts will be provided by mail and email before construction begins.

Construction is expected to start in spring 2019 and will take up to two years to complete.

Other work in the project area:

  • Waterline relocation work occurred in summer 2018 and is now complete.
  • Fiber relocation is expected to take place before the end of 2018.



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

Graham Road will be widened under the bridges and the height of the bridges will be raised to better accommodate truck traffic. A sidewalk and bike path will be built on the east side of Graham Road for pedestrians and cyclists.

What Problem Will This Improve?

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