Some parts of Midtown, including Fifth Avenue and surrounding streets, will become a car-free pedestrian plaza during the coming holiday shopping season, Mayor Eric Adams said Tuesday.

The 11-block traffic shutdown between 48th Street and 57th Street on three Sundays aims to “cement Midtown Manhattan as the premiere international holiday destination,” City Hall said in a statement.

NYPD will erect temporary barricades from noon to 6 p.m. on Dec. 4, Dec. 11 and Dec. 18, the statement said.

Officials plan to repurpose the metal barriers to take one lane of traffic each for pedestrians from Fifth and Sixth avenues during the other six days of the week.

The streets around Rockefeller Center, meanwhile — West 49th and West 50th — will go car-free from 11 a.m. to midnight, seven days a week, starting Nov. 30, the day of the famous Christmas tree lighting.

Local elected officials pushed for the closure in order to address the dangerous crowds that fill the area for the lighting ceremony and throughout the Christmas shopping season.

In recent years the city limited its crowd-control effort to the area immediately around Rockefeller Center.

Adams in a statement called his new plan “bold, creative thinking.”

“Every year, people come from across the world to New York City, and to Midtown Manhattan specifically, during the holiday season,” the mayor said.

“This year, we are going to make that experience safer and more enjoyable for all New Yorkers and visitors with more access to Open Streets.”
