The new Tilikum Crossing Bridge in Portland, Oregon began testing its new ambient lighting system last Thursday and Friday. Morgan Barnard, Douglass Hollis, and Anna Valentina Murch designed the LED light system to change colors according to the data streamed from the U.S. Geological Service river monitor near the Tilikum Crossing Bridge. Those living in the area or using the bridge will not only see the light system change colors throughout the day, but they will also witness large changes in color throughout the course of the year as the time of year affects the river’s speed, temperature, and height.

Historic Oregon Bridge For Sale

If anyone is in the market for purchasing an old bridge here is your chance. Multnomah county in Oregon has put the 88-year-old Sellwood Bridge up for sale until September 12th. The bridge is Oregon's only bridge with a four-span continuous truss holding up the roadway and the only known highway bridge nationally with such distinction. Despite not being listed on the register of the National Register of Historic Places, simply qualifying to be on the list is enough to force the county to put the bridge up for sale. The National Historic Preservation Act states that Multnomah county must seek out potential buyers before they can demolish the bridge.
