If you're heading to New York City for some holiday fun, there will likely be heavy traffic Tuesday in Manhattan.

The Department of Transportation determines gridlock alert days throughout the year based on traffic data from years past.

This is the 12th of 19 this year.

The MTA says your best way to get around will be on its trains.

It offers a City Ticket that allows you use the Long Island Railroad or Metro- North similarly to the subway for a discount.

For example, you could park in the Bronx, hop on Metro-North and go to and from Manhattan.

It's $5 off peak and $7 peak.

You can buy it anywhere you'd normally get a ticket, including on the MTA's Train Time app.
