America turns 243 years old tomorrow.

And for 43 of those years, Macy’s has been hosting a fireworks display that city officials say is “the largest in the nation.”

[The crazy planning for the Macy’s fireworks show begins in the California desert.]

But getting a good view of the pyrotechnics requires some preparation.

The show

The fireworks should start about 9:20 p.m.

In absentia: A televised show, with musical acts, runs from 8 p.m. to 10 p.m. on NBC. You can listen to the fireworks and musical acts on the radio station 1010 Wins.

In person: Fireworks will be launched from four barges in the East River, roughly between Broad Street and the Brooklyn Bridge.

Some locations have better viewing than others

There are “prime viewing locations” on elevated portions of Franklin D. Roosevelt Drive and the Lower Promenade, according to Macy’s website. Here are seven recommended entry points to those areas:

For elevated sections of F.D.R. Drive:

“Almost directly in front of the barges”: Broad and Water Streets
