With the start of the annual United Nations General Assembly, New York City’s busiest traffic time of the year begins. The Department of Transportation has released its list of Gridlock Alert days through the end of 2024. Road closures have already begun for the UNGA, so make sure to check your routes this weekend as well. Traffic data shows average vehicle speeds in the Midtown Central Business District during the General Assembly week drop to under 4 mph, which compares with a slightly more robust 6 to 7 mph on a usual day. There’s some good news for bikers. Over the past four years, the city created a temporary bike lane through the tunnel during UNGA and it has been a success, according to the DOT. That’s why officials are in the process of redesigning the lane to make it a permanent fixture. “This new jersey barrier-protected bike lane will create an express lane for cyclists and micro-mobility users through a portion of midtown,” the NYC DOT’s announcement read. Here’s the list of 2024 Gridlock Alert days, so you can mark your calendars and plan to take public transit: Monday, September 23, 2024 Tuesday, September 24, 2024 Wednesday, September 25, 2024 Thursday, September 26, 2024 Friday, September 27, 2024 Wednesday, November 20, 2024 Thursday, November 21, 2024 Friday, November 22, 2024 Tuesday, November 26, 2024 Tuesday, December 3, 2024 Wednesday, December 4, 2024 Thursday, December 5, 2024 Friday, December 6, 2024 Tuesday, December 10, 2024 Wednesday, December 11, 2024 Thursday, December 12, 2024 Friday, December 13, 2024 Tuesday, December 17, 2024 Wednesday, December 18, 2024 Thursday, December 19, 2024 This story uses functionality that may not work in our app. Click here to open the story in your web browser.
