Significance: Isa Lake Bridge typifies the early design philosophy of the National Park Service, which was to use indigenous materials to harmonize man-made features with their natural surroundings. This philosophy is embodied in many of the park's Rustic Style buildings and structures. The collaboration of the National Park Service landscape architects with the Bureau of Public Roads engineers during the 1920s and 1930s produced many fine examples of this philosophy. Isa Lake Bridge is also significant for its interpretive role in the park. It was carefully designed to promote interpretation of westerly and easterly drainage of park waters into the Atlantic and Pacific oceans.
