Construction is currently underway on the country’s first multi-modal bridge that bans private cars. Instead of carrying private vehicle traffic, the bridge will carry MAX light rail trains, Portland’s streetcar line, city busses, and pedestrian and bike traffic. The decision to ban cars was made mostly because there is not an existing roadway on either side of the bridge. City planners did not want to ruin the redevelopment occuring along the river by carving it up with a new freeway on both sides. The city looked into having the MAX trains travel on the existing Hawthorne Bridge, but decided against that option despite most likely being cheaper than building a new bridge. The bridge, known as the Tilikum Crossing, is being constructed in Portland, Oregon and will be completed next year. The bridge will open for one day in early August for the 19th annual Providence Bridge Pedal and Stride. It will then close again until its official opening on September 12th.
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.
