Sellwood Bridge construction time-lapse

Since 2011, Multnomah County, Oregon, has been working to replace the Sellwood Bridge, a historic span in the Portland area that opened in 1925.

The time-lapse video below chronicles the first five years of construction of the new Sellwood Bridge. The project replaces the 90-year-old, 300-foot span with a 1,976-foot steel arch design that is wider and more seismically sound. In fact, the new bridge is designed to withstand both 500 and 1,000-year recurrence period earthquakes.

Traffic has already reopened and the project is expected to be completed in November 2016. For more information, visit: www.sellwoodbridge.org/
