(Wilsonville, OR) -- ODOT is postponing a major project on the I-5 Boone Bridge south of Wilsonville. Some of the expansion joints on the bridge are broken and need to be replaced. It was going to be a major project with some full closures of the northbound lanes of I-5. The contractor won't be available to do the work until next year. ODOT says temporary expansion joints will keep traffic moving until the project can be completed next year.
