The annual New York City St. Patrick's Day parade will begin Monday at 11 a.m. at 44th Street and Fifth Avenue in Manhattan.
The parade will continue along Fifth Avenue until 79th Street, where it ends.
Road closures will include Fifth Avenue between 42nd Street and 86th Street, and Madison Avenue between 63rd Street and 64th Street. The closures will be in effect between 11 a.m. and 5 p.m.
New York City Mayor Bill de Blasio and the City Council will not participate in the parade because LGBT groups are banned from participating.
While individual members may march on their own, there will be no City Council presence, banner or sergeant-at-arms, marking the first time the City Council has officially opted out of the annual event.
The Long Island Rail Road has scheduled 14 extra trains to accommodate travelers attending the parade.
There will be six extra westbound trains in the morning and eight extra afternoon eastbound trains, according to the LIRR website.
Alcohol will be prohibited on trains, stations and platforms between 12:01 a.m. Monday and 5 a.m. Tuesday, according to the website.
