Traffic Impact
February 2020: work begins on the Willamette River Bridge. Expect one travel lane for each direction over the bridge. Both directions of traffic will be on one side of the bridge while crews work on the other, as it was when the obsolete bridge was removed. The Delta Highway on-ramp to westbound I-105 will have a dedicated lane, so there will not be a second merge point. That should help westbound traffic flow better. Expect the route to remain the same until June.
Lane closures and detours are necessary and will cause backups at times. Expect 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.
March 2020: The southbound Delta Highway on-ramp to westbound I-105 will be completely closed for 8-weeks.
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.
Construction Impacts
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.
Schedule
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.
