Chasm Brook Bridge (1926) was the seventh of 17 bridges constructed along 57 miles of carriage road on Mount Desert Island between 1917 and 1940. It carries Jordan-Sargent Mountain Road over Chasm Falls. It was the last of four bridges required along the Jordan-Sargent Mountain Road.
At 54 feet in length and 25 feet at its highest point, it is a small rustic masonry arch bridge constructed of reinforced concrete and clad with quarry-faced random-laid ashlar granite. The segmental arch, which spans 28-feet 8-inches, springs from the rock ledges and has slender radiating voussoirs and keystones. The parapet walls, topped with large squared capstones, arch upward toward center of bridge and terminate in scrolled endposts, or “curtails.”
Chasm Brook Bridge was completed in 1926 at a cost of $15,202.64.
