Nice stone bridge that takes you over a small creek that juts out from Jordan Pond. The bridge is part of Carriage Trail, and like the road, it is well maintained.

Eagle Lake is the largest glacial lake in Acadia National Park. The wide crushed gravel paths of the carriage roads circumnavigate the shoreline, with access points to the water and dramatic views of the mountains.

At the end of the 19th century, Desert Island became a tourist attraction. The Green Mountain Cog Railway, a cog railway, was in operation from 1883 and took tourists to the summit of Green Mountain, today's Cadillac Mountain (from 1918), where they could enjoy the breathtaking view. The railway ran from Eagle Lake to the summit over a distance of around 1.8 km. When passenger numbers declined, the railway service was discontinued in 1891. In the following years, the railway line was completely dismantled. Today, only remnants of the route remain. The Buckboard Road was built in the late 19th century, leading up to the summit along the north ridge. However, the journey was only possible by horse-drawn carriage and tourists preferred to walk up the mountain. https://www.nps.gov/articles/000/secrets-of-the-summit.htm The paved ‘Cadillac Mountain Road’ was completed between 1929 and 1932. The more than six kilometer long route is considered an exceptional example of construction work in mountainous terrain. https://www.nps.gov/articles/000/motor-road-history.htm
