Portland Bridge Festival THIS Weekend! (Free)
"Radiating like spokes from downtown Portland, the ten bridges that span the Willamette River are central to regional identity, tying the geography and cultures of Portland into a vibrant whole. Beginning with the Hawthorne Bridge Centennial in 2010—followed closely by the Broadway Bridge (2012) and the Steel Bridge (2013) Centennials—we are excited to introduce the PDX Bridge Festival as an annual, citywide cultural arts festival that celebrates the Willamette River Bridges while harnessing the power of Portland’s creative capacity.
The PDX Bridge Festival will reinvent the bridges as a staging grounds for individual works of art and performance."
