BAR HARBOR, Maine – The National Park Service (NPS) announced on March 17 that the carriage roads within Acadia National Park will close to all users beginning March 18. This temporary closure, enacted until further notice, is a protective measure implemented during the annual spring thaw, locally known as “mud season,” to prevent significant damage to the park's historic infrastructure. The decision affects visitors planning to walk, bicycle, or ride horses on these iconic broken-stone paths.
According to the NPS, the onset of warmer weather combined with wet conditions significantly softens the gravel surface of the carriage roads. This softened state renders the roads highly susceptible to damage. Activities such as walking, bicycling, and riding horses during these vulnerable conditions can lead to the formation of deep ruts and disruptive potholes. These structural impairments not only compromise the integrity of the roads but also channel water in ways that can exacerbate erosion across the landscape. The National Park Service emphasizes that this closure is crucial for safeguarding the delicate surface of these unique pathways, ensuring their longevity and preserving their condition for future enjoyment.
The National Park Service will reopen the carriage roads only after the gravel surface has had sufficient time to dry out and become firm once more. This firming process is essential to prevent any further damage from public use. The NPS encourages all visitors to assist in this preservation effort by respecting the temporary closure. This cooperation is vital, as the agency states that adherence to the closure helps protect the carriage roads "for decades to come," underscoring the long-term impact of current actions.
While the carriage roads are temporarily inaccessible, the NPS suggests that visitors can still explore other areas of Acadia National Park. Hikers are encouraged to utilize Acadia’s numerous hiking trails. However, the Park Service advises visitors to be prepared for potentially icy conditions that may persist on these trails during the early spring. Carrying traction devices for footwear is recommended to ensure safety and stability. Additionally, the Park Loop Road remains an option for those wishing to walk or bike. It is important to note that the Park Loop Road itself is closed to motor vehicles until April 15. Visitors choosing to use the Park Loop Road during its motor vehicle closure should exercise caution around closed gates. The NPS also advises vigilance for park vehicles or equipment that may be operating on the road and warns that lingering snow, ice, and winter storm debris might still be encountered.
The carriage roads are not merely functional pathways but are recognized for their historical and engineering significance. Along with their associated coping stones, gatehouses, and distinct stone-faced bridges, these roads represent "the best and most extensive example of broken-stone roads in the United States." This elaborate network of paths provides unparalleled access, offering visitors opportunities to experience both sweeping vistas and intimate, close-up views of the diverse landscapes throughout Acadia National Park.
