This is the longest continuous truss bridge in North America, just a few miles down the Columbia River from Portland Oregon. It was opened August 27, 1966 and cost $24 Million to build. Until 1993 it was a toll bridge. The remains of the toll booths can still be seen on the Oregon side, but the booths themselves have been removed.
I would venture to say that this is probably one of the most photographed features on the Oregon Coast.
