Acadia National Park Roads & Bridges, Mount Desert Island, Bar Harbor, Hancock County, ME
Significance: In many ways the carriage and motor roads of Acadia National Park appear quite distinct. Signs, grade separations, and two picturesque gatehouses remind today's visitors that these two systems were intended to be kept physically separate. Yet the tension between Acadia's carriage and motor roads also lies at the heart of their shared history. Both were built in response to the rise of the automobile and each was influenced by the aesthetic vision of John D. Rockefeller, Jr. It is this common heritage that visitors atop Cadillac Mountain must keep in mind when they watch the sun rise over the horizon from the front seats of their automobiles.
