Portland, OR, August 21, 2026 —
NW Naito Parkway in Portland has partially reopened to most traffic following ongoing demolition work on the Centennial Mills building. The affected section of the parkway, between 9th and 15th Avenues, is now accessible, though the demolition project continues.
Crews are currently engaged in hazardous materials remediation at the former Centennial Mills site. This phase of the project is anticipated to extend for a minimum of two more weeks. The duration is dependent on the successful and safe removal of all identified hazardous substances.
In conjunction with the parkway’s partial reopening, The Fields Park will remain closed to the public. Access to the park will be restricted until safety assessments are completed and officials deem the area secure for public use. The timeline for The Fields Park reopening has not been specified.
