The Statue of Liberty, which has been closed to the public since super storm Sandy struck in October, will reopen by July 4.
The Statue of Liberty was presented to the United States by the French people in 1886. It stands at Liberty Island as a welcome to all returning Americans.
It’s five months since the monument and Liberty Island were shut down after the storm.
While the statue itself was not seriously harmed by the storm, several buildings on the island experienced the terrible flood. The way used by ships carrying visitors from lower Manhattan and New Jersey was also destroyed.
“It’s good news, it’s a little late, but at least it’s there, and now we’ll watch like an eagle to make sure this promise is kept,” Schumer told NBC New York.
In January, the government spent $59 million repairing both Liberty Island and nearby Ellis Island, which was also damaged in the storm. But the officers have not announced when Ellis Island will reopen. In November, more than a million art works had to be removed from the museum there because of the storm. The Statue of Liberty is one of the country’s most popular tourist attractions. According to the National Park Service, more than 3.7 million people visit the site every year.
