Starting October 13, 2026, New York City Transit will adjust J and M subway service in Brooklyn to replace track switches near the Marcy Avenue station. The project will continue through late November 2026.
Why it matters
The track switches at the site have reached the end of their useful life after 29 years of operation. Replacing the hardware is necessary to maintain infrastructure reliability and safety for daily transit users.
Work impacts service across 5 weekends, with M trains operating on a 20-minute frequency. Additionally, J trains will shift to local service between Marcy Avenue and Myrtle Avenue-Broadway on weekdays from 10:00am to 3:00pm.
The players
New York City Transit
This public agency operates the subway system and is responsible for all track maintenance and service scheduling in the city.
The details
Crews will perform the work near the Marcy Avenue station, necessitating the use of free shuttle buses between Myrtle Avenue-Broadway and Delancey Street-Essex Street on weekends. During this time, parking restrictions will be in effect on Broadway between Marcy Avenue and Keap Street.
Timeline
Service changes begin on October 13, 2026.
The first weekend of service disruptions begins on October 17, 2026.
Work is paused for the weekend of October 31 to November 1, 2026.
Regular subway service is expected to resume in late November 2026.
Roadmap
The transit project accounts for the New York City Marathon by pausing construction during the event weekend. This operational planning follows a pattern set by major city events requiring full transit capacity to manage large crowds.
Commuters should prepare for longer weekend travel times due to the 20-minute M train frequency and the reliance on shuttle buses between Brooklyn and Manhattan. Drivers in the area must also note parking restrictions on Broadway near the construction zone.
The takeaway
Reliable transit infrastructure depends on routine hardware upgrades to prevent unexpected failures. Travelers should check current service alerts before heading out on weekends to avoid delays caused by these necessary track improvements.
What happens next
Regular subway service is scheduled to resume in late November 2026 following the completion of the switch replacement project.
