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.
I think part of the difficulty in allowing ourselves to properly delight in the imperfect, comes from conflating delighting in something with wanting it to happen. This isn’t the case. You can appreciate something as it exists while acknowledging its problems. You can see that a fire is beautiful without becoming a pyromaniac, and you can appreciate the absurdity of your political situation without thinking it’s good.
Even if a delight in the imperfect causes you to want more imperfection in your life (and it should), there is no shortage of imperfection to seek out. The imperfect is not scarce, it’s abundant. If you find imperfection delightful, you will never be short of things that delight you, even if you fix any given problem. Solving problems and smoothing out imperfections doesn’t remove the source of delight, it merely opens up new vistas for it. You could give yourself over totally to delight in the imperfect and never run out of things to explore, even without creating your own.
