Four Corners Project - A conceptual sculpture spanning the globe. The project was begun in 1979 and completed in 1985 and consists of an invisible tetrahedron inside the earth with its four corners protruding the surface at Easter Island, New Guinea, South Africa and Greenland. During the five-year project he traveled to each location and installed a marble pinnacle at the exact location of the apexes where the planes meet. The project provides a cultural, geographic, spiritual and aesthetic metaphor and references the Plutonic Solids. Barr describes The Four Corners Project as “an act of constructive creation that has at its core a faith in humanity and a confidence that when we are united by the arts, the world community is most loving, most, sane, and most human”

Sunsweep - A series of sculptures that form an imaginary arc spanning the North American continent from New Brunswick to Roberts Point, Washington. “Sunsweep” commemorates the longest peaceful border in the world. Each sculpture is positioned in a place that can only be reached over land by traveling both through Canada and the US. Each sculpture is positioned to reflect the position of the sun as it passes from east to west from dawn to noon to dusk. “It [Sunsweep] is, as are all of David Barr projects, breathtakingly creative…representing and symbolizing the cohesiveness of the U.S. and Canada.” U.S. Senator Carl Levin, 1985

Arctic Arc - Consists of two complementary sculptures creating an invisible arc across the Bering Strait. In Alaska a sculpture of wood and steel suggests both the frame of a ship and a human hand with a dove rising from it. The corresponding sculpture in Russia again uses both the ship and the hand motif. In Arctic Arc Barr asks the viewer to contemplate the significance of a place where humans first entered North America.
