About
ODOT is replacing two aging bridge joints in the northbound lanes of the I-5 Boone Bridge in Wilsonville, which serves about 120,000 travelers daily.
After repeated repairs since 2008, the two bridge joints are in critical need of replacement. They have previously malfunctioned, creating safety issues for travelers and requiring unplanned maintenance work with travel lane closures. They are now monitored by our maintenance team, who inspects them every two weeks.
Other work on the I-5 Boone Bridge
ODOT is also exploring a plan to replace the existing bridge with a new one that can withstand a major earthquake. This summer, there will be a geotechnical investigation of the area. This includes drilling at the ends of the bridge, in the southbound shoulder and under the bridge. There is no timeline for replacement since both design and construction are not currently funded.

What Problem Will This Improve?
After repeated repairs, two bridge joints in the northbound I-5 lanes are in critical need of replacement. The joints are beyond their service life.
Safety: When steel beams in the joint fail, they can become a safety hazard. Replacing the bridge joints is critical for the safety of the traveling public.
Reduced Costs: The bridge joints require ongoing maintenance inspections and have previously malfunctioned, creating safety issues for travelers and unplanned maintenance work with travel lane closures.
Environmental Stewardship: The joint's rubber glands are not functioning and water, polluted from the surface of the road, is running directly into the Willamette River.
