People who are flocking to the city to catch the famous holiday decorations and events can also expect to see stepped up security from the NYPD.
Police say no credible threats have been made targeting New York City, but officials are taking extra precautions.
Trucks will be restricted in parts of midtown Manhattan, and major bridges and tunnels around the five boroughs will also see increased patrols.
"We are also going to have our SRG, CIC and TSRC teams going all over the city to all the different churches. So we will have heavy weaponry teams responding throughout the city, throughout midnight masses and through the masses on Christmas day itself," says Chief Terence A. Monahan, NYPD chief of patrol.
