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

6th Avenue on-ramp closed Monday, May 20 for about four weeks. Work that has been done on bridge rails and bridge joints with the ramp open allows crews to focus on the resurfacing and bridge joint work requiring a bridge closure to complete.

The 7th Avenue/Washington Street on-ramp and 7th Avenue/Jefferson Street off-ramp will not fully close. There will be lane closures.

7th Avenue/Washington Street on-ramp to EB I-105

  • one lane is now closed for about 10 days for bridge joint replacement
  • two lanes open the remainder of the 6th Avenue ramp closure

7th Avenue/Jefferson Street off-ramp from WB I-105

  • one lane closed for about 10 days for bridge joint replacement
  • two lanes open for the remainder of the 6th Avenue ramp closure​

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

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.

Additional Information

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.
