Located in New York's Brooklyn Bridge Park is Bridge Over Tree, a sculptural installation designed by Iranian-born, Minneapolis-based artist Siah Armajani. The work was first shown as a temporary sculpture in Minneapolis in 1970, and is now on view for the public for the first time in nearly 50 years. It comprises a 91-foot-long bridge and a set of stairs at the sculpture’s midpoint. These stairs send visitors up and down over a small evergreen tree. The sculpture was designed to force complete strangers to pass, interact, and cooperate with one another when passing the center of the structure. In a moment of heated political disagreement, finding common ground with any stranger is a welcome change.
