Tilikum Crossing, the first bridge to span the Willamette River since 1973, opens this week in Portland. Home of Tri-met’s new Orange Line, which connects SE Portland, Milwaukie and Oak Grove with downtown, the bridge is the first of its kind in the United States. It is truly “Portland” in so many ways, including its sleek, cable-stayed design and extra wide pedestrian and bike paths. Tonight, September 10th, a spectacular event associated with the opening takes place, called “First Light.” The 178 aesthetically placed lights on the bridge will be permanently lit at approximately 9 p.m., and will change based on the Willamette River’s speed, temperature and height. The light program was designed by artists Anna Valentina Murch and Doug Hollis as part of Tri-met’s public art program.
