Project Details

Traffic Impact

Paving will begin in late August. It had previously been scheduled for September.

Westbound I-105

• The 6th Avenue off-ramp from westbound I-105 opened on schedule, Friday, July 19.

• Beginning July 29, traffic will be reduced to one lane in the work zone approaching 7th Avenue until mid-August.

• Lane closures continue and change regularly.

• The last four bridge joints are being replaced. 

• Bridge rail replacement continues on the left shoulder.

• The bumps from bridge joint replacement will be there until they are paved over.

• The off-ramp to 7th Avenue/Jefferson Street is open.

Eastbound I-105

• ​The 6th Avenue on-ramp to eastbound I-105 opened on Friday, June 14. 

• Traffic is reduced to one lane on the Washington Street/7th Avenue on-ramp.

• Bridge rail replacement continues on the left shoulder.

• Lane closures continue and change. ​

We're Working on 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'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. 

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

​On the Eastbound Side

6th and 7th Avenue/Washington Street on-ramps are open until paving in September, with lane restrictions on the eastbound 7th Avenue on-ramp. The bumps from bridge joint replacement will be there until they are paved over. Slow down. This is a construction zone.

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

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

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

• 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.

• 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.
