“Up On the On” is a footbridge project by artist Mark Schlesinger that integrates a repeating pattern of painted, textured rocks alongside natural river rocks. Schlesinger uses a polymer stucco material and seeks to combine the urban with the natural. Several of the blocks also glow softly at night.
