Interstate 105 Bridge Preservation Project Update 

A new traffic pattern comes your way Friday night, January 11! Saturday morning, the eastbound lane moves to the far right of the roadway.The traffic shift process takes several stages over a few nights to complete. This work will be done at night to lessen traffic impact. (Friday and Monday nights.)

Tuesday, January 15
, TWO westbound lanes will be available south of the Willamette River Bridge, making travel faster and easier by eliminating the need to merge at the southbound Delta Highway onramp. Road striping and moving concrete traffic barriers are needed before traffic patterns change. Striping is weather dependent. Travelers should expect this new traffic configuration to remain for about six weeks as the second half of an obsolete bridge is removed.

Bridge removal is scheduled to begin on Wednesday, January 16. Demolition work will occur during the day and last about a week.

In other project work, the second half of a bridge joint will be installed in the left lane of the Washington Street ramp, and preparations are being made on the ramp to replace the guardrail.

Many people change their routes to avoid construction but I-105 may be your best route. On TripCheck you can get an update on construction (lane and ramp closure status) and see how traffic is flowing.

What's involved?

The Interstate 105 (Washington/Jefferson Street Bridge) Bridge Preservation Project has several different work areas. I-105 bridges and ramps between Delta Highway and downtown Eugene are being brought up to current standards. The bridges were built in the late 1960s and early 1970s and need repair and upgrades. Work includes new guardrail, deck paving, seismic retrofits, joint replacements, and other repairs.



We continue to revise the project to reflect the most efficient and cost-effective approach to reduce community impacts. However, lane and ramp closures will be necessary to complete the work. Work will occur day and night, and it will be noisy at times. Know Before you Go” with the most up to date information about the project at TripCheck.com. All work schedules are subject to change due to weather.

We are working closely with the City of Eugene, Lane County, Lane Transit District, Point2point Solutions, and other partners to coordinate area construction projects, minimize your inconvenience, and let you know about other available transportation options. Each agency has its projects on TripCheck.com. Access for pedestrians, including those with disabilities, and cyclists is available and identified through or around work zones.

Please check routes before you go and expect delays and detours in work zones. You may travel through several work zones. You may need to adjust your route, your time, or try a new way of getting where you are going. Updates on construction are sent to the mailing list on a regular basis as work continues.

We appreciate your patience! We promise to get in, get done and get out as quickly as we safely can. The end result will be a safer and more reliable transportation system that connects people and helps Oregon’s communities and economy thrive.
