The nine-day suspension of A train service along Liberty Avenue in Queens ends at 5 a.m. Monday, Nov. 16. Since Nov. 7, the MTA has replaced trains between Rockaway Boulevard and Ozone Park-Lefferts Boulevard with shuttle buses while crews replace track and switches for signal modernization (CBTC). Road closures around Liberty Avenue this weekend lift at the same time.
The suspension of A train service along Liberty Avenue in Queens ends at 5 a.m. Monday, Nov. 16. According to the Metropolitan Transportation Authority (MTA), trains stopped running between the Rockaway Boulevard and Ozone Park-Lefferts Boulevard stations at 12:30 a.m. Saturday, Nov. 7, and free shuttle buses have covered that stretch since. Starting with the first morning commute on Monday, the A train will again run all the way to Lefferts Boulevard.
The work is part of the conversion of the A and C lines' signal system to communications-based train control (CBTC). The MTA described the project as replacing the oldest signal equipment in the subway system, installed in the 1930s. Over the nine days, crews replaced all of the ties, rails, third rail and switches in the stretch, and installed temporary stair structures and shielding beneath the tracks.
Substitute Service and Road Closures Through This Weekend
During the work, A trains ran only from Rockaway Boulevard toward Howard Beach-JFK Airport, and the overnight Lefferts shuttle between Lefferts Boulevard and Euclid Avenue was also suspended. Shuttle buses run every 3 to 5 minutes during rush hours and every 10 minutes at other times. Riders can also take the Q112 on Liberty Avenue, the Q8 on 101st Avenue and the Q41 on 109th Avenue and Rockaway Boulevard at the regular fare, but those three routes do not run overnight.
Because of work on the elevated structure, through traffic is blocked on Liberty Avenue this weekend, from 12 a.m. Nov. 14 to 5 a.m. Nov. 16. 99th Street and 100th Street between 103rd Avenue and Rockaway Boulevard are also closed to through traffic. Northbound traffic on Liberty Avenue is detoured to 103rd Avenue between 98th and 104th Streets, and southbound traffic is detoured to Rockaway Boulevard between 101st and 96th Streets. These closures also lift at 5 a.m. Nov. 16.
The work is not entirely over. The MTA said this nine-day shutdown is the first in a series of suspensions for CBTC work, and weekend and overnight work will continue throughout 2027. Riders should check service status before they travel, using the service change lookup at mta.info, the MTA app or the 511 phone line.
