The Lines of the West-Side Elevated Highway in Two Parts by Stephen Korns (b. Amherst, MA) is a series of lines painted on the road surface articulating building and open-space features over a two-mile section of the West Side Highway. The lines function as visual keys to features of structural change, points of transition in vista, and cityscape units. Each line is made up of multicolored stripes, and the spacing among these stripes and the ordering of their colors has been designed specifically for each location. Standard highway marking colors of yellow, black and white reflect the roadway nature of the piece, as does the painting technique of using conventional safety-striping equipment.
