Project Details

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

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

Monday, October 29, lane closures and traffic changes begin on I-105 south of the Willamette River. Both directions of traffic will move to the westbound lanes, separated by concrete barrier.

This closure will be in effect 24 hours a day for six to eight weeks. Traffic will then move to the eastbound lanes. During the second closure, the ramp from southbound Delta Highway to I-105 will be closed. ​

Lane closures and detours are necessary and will cause large backups at times. Expect delays, 24-hour lane closures, and ramp closures. Plan ahead. Give yourself more time, take a different route, and try carpooling, the bus, walking or biking if you can.

Construction Impacts

​Parts of this project will be noisy.  

The multi-use paths underneath the Willamette River Bridge will 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. 

Exact timelines have not been finalized, but during part of the project there will be closures of the southbound Delta Highway ramp to I-105 westbound and the I-105 ramps at 6th and 7th. Notice of closures will be given well in advance.  

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 is being removed and fill added to make the section regular, paved road as the first portion of the project.
