Duck Brook Bridge

Duck Brook Bridge arches over a fast-moving stream, framed by pines and rugged granite near Acadia National Park.

A stone-faced reinforced concrete arch bridge spans a steep Duck Brook ravine, its deck perched above a mossy gorge and a sparkling stream. Parapet viewing platforms on both sides offer sightlines into the surrounding forest as Duck Brook threads the gorge below. The ravine was carved by glacial erosion, and the bridge was built between 1929 and 1953 as part of Rockefeller's carriage roads.
