Project Details

I-105 Bridge Preservation Project

Construction Phase

Region 2: Willamette Valley and Northwest Oregon (Eugene, Lane)

I-105 bridges and ramps between the Delta Highway interchange and downtown Eugene are being repaired, repaved, and getting seismic upgrades. ​​​​​​​


Traffic Impact

Lane closures change as needed and crews are onsite day and night in the project area. All schedules may change, depending on the weather.

There's also the potential for increased traffic, especially during the evening commute hours, on other routes through Eugene such as Country Club Road, Coburg Road, and the Ferry Street Bridge area. 

Pay attention and let your fellow travelers merge. Use all of the travel lanes and merge like a zipper.

Don't block intersections and watch for bikes and pedestrians on surface streets.

Traffic delays are minimal most of the time.
Lane closures and detours are necessary and will cause backups at times during the project. Expect delays, 24-hour lane closures, and ramp closures as the project continues. Closure schedules will be announced well in advance.


Construction Impacts

Lane closures are occuring throughout the project on different parts of the bridge.​ Parts of this project will be noisy.  

The multi-use paths underneath the Willamette River Bridge remain open on both sides of the river during construction. Protection measures will be in place to ensure the safety of people on the path from work being done on the bridge above.   


Work on the Willamette River Bridge and Delta Highway on-ramp will begin in early 2020.  That will be the final portion of the project. Expect lane and ramp closures.

The project will be completed in early 2021.



I-105 bridges and associated ramps between the Delta Highway Interchange and downtown Eugene were built in the late 1960s and early 1970s and are in need of repairs and upgrades. Work to be done includes:

  • Installing guardrails that meet current crash standards 
  • Paving
  • Seismic upgrades
  • Replacing bridge joints

One section of the road was actually a bridge that was to go over a highway that was never built. It was removed in the first portion of the project.

Additional Information

What are the bumps in the road?
  • They are the replaced bridge joints.
  • They will go away as the road is repaved.
  • Slow down to cross them. This is a construction zone.
  • It takes about 10 days for each to be replaced, including concrete drying time.
Why did this project begin in the fall?
  • Bridge work and concrete paving can be done any time of the year.
  • Longer, year-round projects begin throughout the year. This helps ODOT and our contractors better plan and balance the use of employee and equipment resources
Is construction done around the clock?
  • Most construction is not around the clock, but will be at times.
Why doesn't TripCheck show traffic delay information?
  • The color coding of the road shows how traffic is moving, but not the time it will take. It also shows any incidents that may be occurring, like disabled vehicles or crashes. We don't have the technology in place to show real time travel time on I-105 right now.
City of Eugene traffic cameras added to TripCheck
  • City of Eugene traffic cameras have been added on 6th and 7th Avenues for additional information on traffic.
  • Four cameras have been added to Coburg Road.
Many people changed routes to avoid construction but I-105 may be the best way to get where you are going. On TripCheck you can get an update on construction (lane and ramp closure status) and see how traffic is flowing.
Do not block intersections, and be aware of bikes and pedestrians. Good weather means more people get out of the car and avoid the backups. Watch for them.
Eugene Police Department is increasing patrols in the area.
Practice work zone safety. Watch for crews and help us all get home.
