Bronze sculptures created by Erin Robertson and Anna Williams entitled, Bellwether, were installed at the Longfield Transit Station in 2011. The artwork is composed of life-sized sculptures of four sheep and a border collie herding them across a green roof.
Bellwether is a permanent sculptural installation, primarily located on the vegetative roofs of the transit station, which consists of four life-sized sheep and one life-sized Border collie sheepdog all cast in bronze and finished with patina.
Bellwether is intended to create an overall sense of the movement of a community through a designated space. It investigates the subtleties of various roles and relationships within established groups. Playfully comparing the contemporary public transit system to traditional agricultural herding practices, the installation is suggestive of social cooperation and adaptation which are both characteristics of an effective transit system.
