Highway 86 is a winning competition entry for public space at the 1986 Canadian World Exposition, celebrating the history of 20th Century air, land and sea transportation. The structure is a seven hundred foot long undulating ribbon of concrete and steel for the purpose of exhibiting all means of mobility as part of a participatory sculptural event. Territories of the project include an area underneath two automotive viaducts, adjacent spaces for various national and corporate pavilions, plus a shoreline segment overlooking the Vancouver harbor. Acknowledging people's ambivalent relationship to the future of industrial technology, an all-inclusive coating of monochrome gray unifies the vehicles and reinforces this state of ambiguity.
