NEW YORK — It's New York City's version of American as apple pie: hot dogs, a heart-racing turn on the Cyclone or a scenic spin on the Wonder Wheel at Coney Island's historic amusement park on July Fourth.
But this year, an aging, swaying observation tower appears poised to scuttle the summer ritual, putting visitors' plans and merchants' hopes on a roller coaster ride of their own.
After concerns about the 275-foot-tall Astrotower abruptly shuttered the park Tuesday evening, the roller coaster, Ferris wheel and some other attractions remained idled Wednesday. The park's managers said they planned to remove part of the needlelike structure, making it unlikely the amusements could reopen Thursday.
"We're going to do everything we can to keep this park open," Buildings Commissioner Robert LiMandri said, but authorities said they needed to keep a chunk of it closed and even rope off part of Coney Island's famous boardwalk until they could be sure there was no danger.
While the beach, a carousel, some other amusements and Nathan's Famous — home of the July Fourth hot dog eating contest — were open, the developments had tourists trying to figure out whether to rejigger plans and vendors wishing they wouldn't have to.
"You've waited for a whole year. You just wait for this day," Victor Summers said as he stood next to the 3-D simulator ride he's operated in the shadow of the Astrotower since 1996.
"The Fourth of July — it's like Christmas for Coney Island."
The holiday cliffhanger centers on a spindle that has stood over Coney Island for nearly half a century, a beacon for a its beachfront entertainments and a memento of the space-race era in which many of them were built.
