Just prior to yesterday’s groundbreaking ceremony (video here) for the new transit bridge over the Willamette river, Rob Barnard, TriMet’s director of the Portland-Milwaukie Light Rail Project, gave a presentation covering the bridge design and construction techniques. He also took a few questions from the audience. Rob’s PowerPoint slides are integrated into this video, along with some additional footage and maps.
