original passage: From 1915 to 1940, the wealthy philanthropist John D. Rockefeller Jr. financed, designed, and directed the construction of a network of carriage roads throughout the park. He sponsored the landscape architect Beatrix Farrand, whose family owned a summer home in Bar Harbor named Reef Point Estate, to design the planting plans for the carriage roads (c. 1930). The network originally encompassed about of crushed stone carriage roads with 17 stone-faced, steel-reinforced concrete bridges (16 financed by Rockefeller), and two gate lodges—one at Jordan Pond and the other near Northeast Harbor. About of carriage roads are maintained and accessible within park boundaries. Granite coping stones along carriage road edges act as guard rails; they are nicknamed "Rockefeller's Teeth." The carriage roads are open from the end of the spring mud season, generally in late April, through the summer, autumn, and winter months, until the following spring thaw causes another closure in March to prevent damage to the gravel surface.
