Significance: The Triple Arches is one of approximately seventeen prominent masonry and concrete structures on Going-to-the-Sun Road in Glacier National Park. The 51-mile stretch of scenic road is significant as a unique engineering accomplishment of the early twentieth century, and as the first product of a 1925 cooperative agreement between the National Park Service and the Bureau of Public Roads. The Tripe Arches, a unique three-span half-bridge, was a more creative, less expensive, and less imposing design for this site than a solid masonry retaining wall would have been.
