Gridlock Alert Days

DOT Traffic Congestion 5th Avenue Midtown Manhattan

Coined in New York City, the term gridlock means traffic congestion that blocks a city’s network of intersections and has been used to describe the Manhattan core’s overwhelming traffic volume in general. Despite the number of vehicles on our streets, New Yorkers most often choose from a variety of available transportation options including regional rail lines, the 24/7 metropolitan subway and bus system, ferries, cycling, and walking.

NYC DOT designates the busiest traffic days of the year as Gridlock Alert Days. Whether traveling for work, errands or recreation, please consider walking, biking or taking public transportation whenever possible.
