The National Park Service reopened a popular route to the top of Acadia’s Cadillac Mountain to motor vehicles Friday, a day after closing it temporarily because of the government shutdown.

Cadillac Summit Road was closed to cars Thursday, the second day of the shutdown, before fully reopening Friday morning. As the shutdown continues, decisions about the road’s closure will be made on a daily basis, according to a notice posted on the Acadia National Park website.

The road remains open to pedestrian and cyclists.

The post on the park’s website says the availability of future vehicle reservations, which cost $6 and are required to drive the road, may be canceled and refunded without prior notice if the road is closed.

The park service has also closed the Hulls Cove Visitor Center and the Sieur de Monts Nature Center until further notice.

While most of Acadia remains open, only staff deemed essential to the protection of the park and the health and safety of visitors are still working. The long-term impacts on the park remain unclear.

Acadia, annually one of the most visited in the national park system, is “down to a skeletal group” of employees considered essential, Everal Eaton, executive director of Bar Harbor Chamber of Commerce, said Wednesday.

“The park is open,” Eaton said, “but you might notice some changes.”

The U.S. Department of the Interior provided a National Park Service Contingency Plan in preparation for the shutdown, but it notes that every park is unique and the application of the guidelines may vary from park to park.

Some “visitor services,” such as restroom cleaning and trash collection, may continue, according to the plan. Other roles could be retained in order to oversee these services, including some administrative, financial and human resources positions.

Editor’s note: This story was updated on Oct. 3 to reflect that the road has reopened to vehicular traffic and that future decisions on whether to close it will be made on a daily basis.
