Recorded for this place
South Triad’s Wooded Summit“You're approaching the South Triad trail access, for a short climb through granite and spruce. Allow about an hour for the roughly one-mile return hike, with a steep, uneven start that becomes harder on wet rock.”

Guide
Triad-Day Mountain Bridge is a pink-granite-faced carriage-road bridge over Day Mountain Motor Road in Acadia National Park. It links the Bubble Pond carriage road to the north with the Barr Hill-Day Mountain and Day Mountain Loop roads to the south, so it makes most sense as a detail on a longer carriage-road outing. The bridge is on the route itself; no nearby parking point or approach distance is established, so don't plan around an unverified drive-up stop.
The structure is reinforced concrete faced with quarry-faced pink granite, including under the arch. Its segmental arch spans 34 feet 8 inches; the full bridge is 74 feet 6 inches long and 20 feet 6 inches at its highest point. Look for the slender wedge-shaped stones radiating around the arch, squared granite capstones, and the stepped masonry walls along the road. If you have a safe place clear of the travel way, frame the arch with the road beneath it; that shows how the crossing works.
Completed in 1940, it was the 17th and final bridge in the 57 miles of Mount Desert Island carriage roads built between 1917 and 1940. The National Park Service built it after John D. Rockefeller, Jr. granted a right-of-way while transferring land and roads into public park ownership. Its design recalls the earlier Rockefeller bridges, especially Stoughton's Jordan Pond Road Bridge.
