ACADIA NATIONAL PARK — After being closed since April for a major rebuilding of the walkways and safety railings, Thunder Hole here has reopened to the public two weeks ahead of schedule.
The entire viewing area at Thunder Hole, one of the most popular visitor sites in the park, had been roped off.
Keith Johnston, the park’s chief of facilities maintenance, said the viewing platform and stairs at Thunder Hole were in serious need of repair. Before the project began he said, “The saltwater environment has completely dissolved all the masonry in the granite work around the structure, so we’re removing it. Basically, everywhere there is granite, the masonry joints have turned to sand, and stones throughout the entire structure are falling out of place.”
Granite facades were reinforced and concrete tinted to match the existing rocks.
Work also is continuing this spring to rehabilitate several stone bridges on the Park Loop Road. In some cases, larger vehicles will be required to take detours. Find out more at www.nps.gov/acad.
