The Uniformed Firefighter Association is issuing a warning against Mayor Bill de Blasio's Rockefeller Center holiday car ban.

UFA says the ban will lead to citywide gridlock. Starting Friday, the city plans to enact temporary closures for several streets surrounding the Rockefeller Center Christmas tree.

These closures will prohibit traffic on 47th, 49th and 51st streets between Fifth and Sixth avenues.

UFA President Gerard Fitzgerald issued a statement reading in part," The move to increase 'pedestrian space' surrounding Rockefeller Center is misguided and makes the city less safe as it is. Traffic is interfering with our firefighter's abilities to reach the scene of a fire, but this new plan will have wide-felt repercussions in the form of traffic from river-to-river."
