Project Details

I-105: Willamette River Connectors and 1st to 7th Ave Viaducts Bridge Preservation

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. ​​

Impacts

Traffic Impact

June 10 - Westbound lane closures begin.

June 15 - The 6th Avenue on-ramp to eastbound I-105 opens.

June 24 - The 6th Avenue off-ramp from westbound I-105 closes for four weeks.​​

All lanes and ramps will be open during the Lane County Fair, July 24-28. Work on the shoulders of the road will continue. ​

We're Moving to the Westbound Lanes

Expect extensive lane and ramp work from June 10 through the end of August. Fewer open lanes and a ramp closure means more delays on I-105. There 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. 

7th Avenue/Jefferson Street off-ramp will be open throughout construction, but will be reduced to one lane at times. 

​On the Eastbound Side

6th and 7th Avenue/Washington Street onramps will be open after June 15 until paving in September. The bumps from bridge joint replacement will be there until they are paved over. Slow down. This is a construction zone.

Pay attention and let your fellow travelers merge. Don't block intersections and watch for bikes and pedestrians on surface streets.
 

Traffic delays are minimal most of the time.

Bridge joints are being replaced on the Washington and Jefferson Street ramps. Traffic patterns will shift as the work moves.

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.   

Several two week closures of the Washington/Jefferson Street Park, including the restrooms, are planned. Otherwise, the park and restrooms will remain open during construction. The park cannot be closed between June 1 and September 1, or December 27 - January 3, unless there is an emergency need.

Schedule

June 10 - Westbound lane closures begin.

June 15 - The 6th Avenue on-ramp to eastbound I-105 opens.

June 24 - The 6th Avenue off-ramp from westbound I-105 closes for four weeks.​


The project will be completed in early 2021.

About

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 is actually a bridge that was to go over a highway that was never built. Now that bridge needs repairs. Since it is not needed, the bridge was removed and fill added to make the section regular, paved road as the first portion of the project.

Cost and Funding

​Project Budget: $18 million

Contractor

​Wildish Standard Paving

Additional Information

Why do the ramps have to close? 

  • ​There isn't room to complete all the work that needs to be done with the ramp open.
  • Bridge joint replacements leave large holes in the road which means the road surface needs to be replaced
  • Siesmic reinforcement requires closures

What are the bumps in the road?

  • They are the replaced bridge joints.
  • The road will be repaved entirely in September.
  • 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. The 6th Avenue ramp work will be done seven days a week, with day and night shifts. You will see around the clock work when the project is something that can be shortened with more time spent.
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 are being added to Coburg Road.

Reminders

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.


Access for pedestrians, including those with disabilities, will be available and identified through or around work zones.

This can be made available in an alternate format on request by calling 503-373-7093 or via the Oregon Telecommunications Relay System: 7-1-1
