March 2020: As of Wednesday, March 4, the southbound Delta Highway and Valley River Center onramp to westbound I-105 is completely closed for eight weeks of construction. The ramp is scheduled to reopen at the end of April.
Detour: The detour from southbound Delta Highway will go to the Valley River Center off-ramp. Turn left over Delta Highway, then turn right and take Country Club Road back to westbound I-105.
The westbound lanes of I-105 will remain closed for construction until mid-June. Both directions of traffic are down to single lanes in the eastbound travel lanes.
All lanes will be open from mid-June until late July for local events, then the eastbound lanes will close through the fall and both directions of traffic will be in single lanes in the westbound travel lanes.
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.
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.
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.
