Akana construction specialists provided Design Quality Manager services for the Willamette River I-5 bridge replacement project.
Named by ENR as the 2014 Best of the Best Bridge Project, the project replaces the existing bridge on I-5 over the Willamette River at Eugene and replaces a second structure over a canoe canal. In addition to design quality control, we prepared the Project Quality Plan and directed the design review process for the bridge design team led by OBEC Engineers and TY Lin International.
The replacement bridge is two parallel concrete deck arch structures with two piers in the main channel of the river. The project is the largest CMGC transportation project in the State of Oregon and consists of demolition of the existing Willamette River Bridge, construction of the replacement bridges, reconstruction of the roadway approaches plus retaining walls, sound walls and major improvements to a park area and pedestrian path under and adjacent to the bridge. Work was funded under the Oregon Transportation Investment Act, a $2.5 billion program to upgrade bridges on major transportation corridors throughout the State of Oregon. QC activities required extensive interaction with the Oregon DOT, its project management consultant, the design team, and the CMGC team.
