The 49th Macy’s 4th of July Fireworks show is an iconic event in the region to celebrate the country's birthday. Here are some answers to your questions about the show's details and where to view it.

The show will be televised nationwide on NBC and simulcast live on Peacock from 8 to 10 p.m. An encore presentation will be aired at 10 p.m. on NBC.

The fireworks will be launched from four barges between Pier 17 and the Downtown Manhattan Heliport on the lower East River in the Seaport District. For the first time, the East and West Towers of the Brooklyn Bridge will also feature projected mapping of animation and colors to complement the fireworks.

The show does not sell tickets and does not sell VIP tickets at any viewing location. Macy’s doesn’t endorse or participate in any venues along the viewing path of the show. This is a free public event.

This year, it will be Academy Award-winning actor and singer Ariana DeBose.

This year’s performances include the Jonas Brothers, Eric Church, Lenny Kravitz, Ava Max, Keke Palmer, Trisha Yearwood, and a musical score created by six-time Grammy Award-winning musician Ahmir "Questlove" Thompson and record producer James Poyser. They will perform on The Rooftop at Pier 17 live from New York City.

Fireworks will include crackling crown jellyfish, atomic rings, yellow and green sunbursts, strobing lemon cascades, comet fans and more before Macy’s Golden Mile. The show is said to launch more than 80,000 shells some 1,000 feet into the sky, made possible through Macy’s Studios in collaboration with Pyro Spectaculars by Souza.

There are several companies, including Circle Line Sightseeing Cruises, North River Lobster Company and American Princess Cruises, that offer cruises providing views of the fireworks.

Brooklyn Bridge Park and sections along Pier 16 and Pier 17 at the Seaport District will be accessible only via free tickets issued by the City of New York.
