N Willamette Blvd Now Open with No Restrictions

Please be advised that construction personnel will be working at the project site periodically in the coming weeks to complete minor facets of the work.

Project Description

The goal of the Project is to replace the aging overhanging bridge structure that carries traffic along N Willamette Blvd between N Chase Ave and N Washburne Ave. The existing structure will be replaced by a retaining wall supported on deep foundations, designed for resilience to earthquakes and landslides. Concurrent with the retaining wall work, we will also make pedestrian and safety improvements to the existing retaining walls in the Project vicinity. Additionally, the Portland Water Bureau will be on site to replace a section of its 100 year-old water line in the area and relocate it further away from the steep slope.
