Every New Year’s Eve an estimated million people flood Times Square for the ball drop, not to mention the thousands heading to parties, packing out bars and attending concerts throughout New York City.

And while the excitement coursing through the streets can be fun, it also means more people relying on public transportation to get around. Add in that New Year's festivities fall on a weekend, when subway service is typically curtailed due to ongoing MTA projects, and well, things could get confusing.

Here is everything you need to know for the New Year's Eve holiday weekend.

Subways

Subway routes in midtown on Saturday will operate every 8 to 12 minutes until 3 a.m. Sunday.

Straphangers should avoid the 42nd Street-Times Square station (1, 2, 3, 7, N, Q, R and S) on New Year’s Eve, as the station’s street-level exits are subject to closure by the NYPD, the MTA said. Instead, subway riders should use the underground passageway to exit via Eighth Avenue-42nd Street.
