Rockefeller financed 16 of Acadia’s 17 stone-faced bridges, each unique in design, to span streams, waterfalls, roads, and cliff sides. The bridges are steel-reinforced concrete, but the use of native stone for the facing gives them a natural appearance. Over time, the stone cutters grew very skilled and Rockefeller often requested them not to cut the facing too well lest the rustic look be lost! The result of Rockefeller’s vision and attention to detail is an integrated system of carriage roads that blends harmoniously with the landscape.
