Cloud Arch is a proposed public artwork by Junya Ishigami for George Street, Sydney. The sculpture is proposed to be a ribbon of twisted, white stainless steel, representing the shape of a cloud, originally designed to be 58 metres (190 ft) tall and with a span of 53 metres (174 ft). It is intended to "frame" the Sydney Town Hall, and be visible from all approach directions as part of the pedestrianisation of the street.
