Bar Harbor, Maine – Cadillac Summit Road reopened today as paving and culvert replacement work on the road pauses for the summer season. Because of the road’s uneven surface, bicyclists and pedestrians are encouraged to use caution when traveling on the road.

The construction, which includes repaving and culvert replacement, began last fall and continued into November when the contractor suspended work due to the onset of winter conditions. Throughout the spring, the contractor repaired culverts under the road and prepared the road for repaving. Single lane closures may continue throughout the spring, and the repaving of the road will resume at a later date.

The NPS expects Park Loop Road to experience single lane closures along Ocean Drive throughout the spring. Expect traffic delays and plan your visit accordingly.

Vehicle reservations will be required for Cadillac Summit Road from May 24 through October 22, 2023. For the most up to date information on reservations, please visit
