G subway service to be partially suspended this summer: What to know

BROOKLYN, N.Y. (PIX11) – G train subway service will be partially suspended in Brooklyn and Queens during three phases this summer, resulting in major service changes for riders.

An MTA signal modernization project will cause G line service disruptions starting this Friday and continuing through Sept. 3.

G trains won’t run between Court Square and Nassau Avenue in either direction from June 28 to July 5, skipping stops at Court Square, 21st Street and Greenpoint Avenue. 

G trains won’t run between Court Square and Bedford-Nostrand avenues from July 5 to Aug. 11, skipping stops at Court Square, 21st Street, Greenpoint Avenue, Nassau Avenue, Metropolitan Avenue/Lorimer Street, Broadway, Flushing Avenue and Myrtle-Willoughby avenues. G trains won’t run at all from 8:30 p.m. on Aug. 11 to 5 a.m. on Aug. 12.

G trains won’t run between Bedford-Nostrand avenues and Church Avenue from Aug. 12 to Sept. 3, skipping stops at Classon Avenue, Clinton-Washington avenues, Fulton Street, Hoyt-Schermerhorn, Bergen Street, Carroll Street, Smith-9th streets, 4th Avenue-9th Street, 7th Avenue, 15th Street-Prospect Park, Fort Hamilton Parkway and Church Avenue.

Shuttle buses will run in place of ​the subway service, with buses stopping at all ​stations where service is suspended, according to the MTA.

The service changes are the result of MTA work to replace 90-year-old signals used by the G line with new communications-based train control technology.

The signals date back to the 1930s and are a frequent source of service disruptions and delays on the G line, according to the MTA.

“Replacing 1930s era signals and infrastructure will dramatically improve service reliability for ​ G train customers,” MTA Construction and Development President Jamie Torres-Springer said. “A phased outage is the best way to deliver this project in the most cost effective way while also minimizing long-term impacts for riders.”
