Routine design When we think of bridges, it is the dramatic and monumental long spans that come to mind first, especially the lithe suspension bridges such as the Golden Gate and the pure geometric arches such as Sydney Harbour. But the majority of bridges are not such spectacular structures. Most of them are ordinary overpasses, with spans of 30 or 40 feet, carrying roadways or rails across other thoroughfares or over small streams. You see such bridges by the dozen on any drive down the Interstate. They may be lacking in glamour, but they are more representative of a bridge builder's art. The engineering and construction of girder bridges are pretty routine these days, but the bridges are not quite standard items you order from a catalogue. The girders, whether of steel or concrete, are custom-build for each bridge, then trucked to the site and hoisted into place with a crane. The designer still has scope for variation and creativity, and it shows out on the highways: some overpasses are prettier than others.

Be A (Re)Visitor An Article by Rob Walker robwalker.substack.com I was thinking about this not long ago while reading in Petapixel an essay by a photographer named Scott Reither, “Long Form Study: Why Photographers Should Repeatedly Revisit A Scene.” In it, he described photographing one particular stretch of beach, over and over, throughout his career. Of course that landscape has changed over time, and of course he’s had moments when he felt he’d captured the same territory so many times there was nothing left to see. But there was always something more to see — maybe because of a change in Reither’s life, rather than in the physical environment. seeingchangephotography
