I have had a love bordering on fanaticism of the columns and curves that make up Seattle’s urban freeways. They are full of rhythm and strength. In the twilight, the eye turns them into ribbons of undulating color, and a rainy day brings out slick silver, shimmering gray beauty to an overpass. There are as many ways to paint them as Monet painted Rouen Cathedral in its various atmospheres.
The freeways are akin to Greek temples with their columns and lintels, but with the amazing exception of the curve. Advanced construction materials have given these modern temples the gift of feminine elemental turns — curves that catch light and bring lyricism to an otherwise stoic monument.

That last one is gorgeous, and VERY west coast!
