I-5 Rose Quarter Southbound Lane Closure and Repair Project

planned

All southbound lanes of Interstate 5 through Portland’s Rose Quarter will close around-the-clock beginning Sept. 11 for up to five weeks as crews perform critical repairs and safety improvements along a 2-mile stretch. The project targets an elevated section of I-5 south of the Moda Center that has deteriorated due to decades of use, including cracks, potholes, and structural wear. Crews will remove and replace concrete surfaces and repair the underlying structure. Work will also continue on seismic and safety upgrades already underway since fall 2025. The closure approach is considered faster, safer, and less costly than extended partial closures.
