NEW YORK — The Fourth of July fireworks show over New York City is the biggest in the country, and this year will be Macy’s 40th anniversary of lighting up the sky in honor of our nation's birth.

More than 3 million people are expected to line the East River in Manhattan, Brooklyn and Queens to watch.

“It takes about 10 days to load the show. We have over 50 licensed pyrotechnicians who are working to load each individual firework into their firing mortars,” Macy’s spokesperson Orlando Veras said.

The barges are loaded up off a pier in Staten Island before being moved to the East River on July 4.

“Like every event that we do in New York City, we work with the NYPD and many agencies to secure the locations and make sure we have the safest show,” Veras said.

Gary Souza, of Pyro Spectaculars by Souza, has been putting together this show for decades.

“You get the powder in your blood, as my dad used to say. We are a fifth-generation family, so you are kind of born into it,” Souza said.

There is a new interactive element this year: spectators can download the Makelight App, letting their phones synchronize with the fireworks show.

“I think that’s going to make almost like a glittering effect,” Souza said.

According to Macy’s, this is the largest display of fireworks in more than a decade.

There are four barges between East 23rd and East 37th streets and one downtown by the South Street Seaport.  Start time is 9:25 p.m. Monday.
