Commuters on the F line in Brooklyn are preparing for disruptions this weekend, and over several upcoming weekends, as the MTA begins extensive maintenance work.

F train service will be suspended between the Jamaica-179th Street and Church Avenue stations on designated weekends. That includes this weekend, when service will be suspended from 12:15 a.m. Saturday through 5 a.m. Monday.

During these periods, free shuttle buses will operate between Church Avenue and Coney Island-Stillwell Avenue.

Service is also expected to be impacted during the weekends of July 12 through July 15, Aug. 9 through Aug. 12, Aug. 16 through Aug. 19, Aug. 23 through Aug. 26, Aug. 30 through Sept. 3 (which is Labor Day Weekend), Sept. 6 through Sept. 9 and Sept. 13 through Sept. 16.

Outside of the weekend closures, Coney Island-bound F train service began operating express between Church Avenue and Kings Highway on July 1 and will continue to do so through July 13. Manhattan-bound F trains will operate express between Kings Highway and Church Avenue between Aug. 5 through Aug. 17.

The work is part of the final stages of the MTA’s Culver Line Signal Modernization project. The project is replacing signals from the Church Avenue station, which serves F and G trains, to the West 8th Street-New York Aquarium station, which serves F and Q trains.

The MTA said the project will help “to improve reliability and resilience" along the line, while also "removing and decommissioning equipment that has reached the end of their useful life.”

The maintenance on the F line follows recent work on the G line, which began on June 28.

Similar to the F line work, the MTA expects the G line work to conclude in early September, when updated signal systems will enhance service reliability along the line.
