A day at the bridges, Portland style

Portland, Ore., has been dubbed many things, including bridge town. Here are two of the most distinct ones: St John’s Bridge (1931) and the Fremont Bridge (1973). The former dates from the Depression, when public works projects had a sense of artistry. The latter was built to serve one purpose–carry cars over Willamette River on Interstate 405 as efficiently as possible. More bridges are to come.
