Here we go again.

There will be no G train service between Court Square and Bedford-Nostrand Avenues on select weeknights and weekends starting July 14 through Aug. 18 as the MTA resumes work on its long-running signal modernization project.

The outages will take place overnight from 9:45 p.m. to 5 a.m. and on weekends from 9:45 p.m. Friday through early Monday morning.

“The G train’s signal system dates back to the 1930s and is now being modernized with state-of-the-art Communications-based Train Control (CBTC), which will bring more reliable service to the 160,000 riders who take the G every day,” the agency said in a press release.

According to the MTA, the nearly century-old signals have been a major cause of service disruptions and delays.

G train riders already endured a “summer of pain” last year, when large sections of the line were shut down for upgrades. Since then, the MTA has completed three more phases of round-the-clock outages.

The project, budgeted at $368 million, is the agency’s first “design-build” signal modernization effort — a contracting method meant to streamline work and reduce costs. The new signal system is expected to go live in 2027.

During the shutdowns, fare-free shuttle buses will replace train service between Court Square and Bedford-Nostrand Avenues. The buses will stop at every affected station and run every three to four minutes overnight and every five to 10 minutes on weekends, depending on the time of day. Train service will continue to operate between Church Avenue and Bedford-Nostrand.

Here are the upcoming closures:

• Overnight closures from 9:45 p.m. to 5 a.m.:

  • Monday, July 14 to Friday, July 18
  • Thursday, July 24 to Friday, July 25
  • Monday, Aug. 4 to Friday, Aug. 8
  • Monday, Aug. 11 to Friday, Aug. 15

• Weekend closures from 9:45 p.m. Friday to 5 a.m. Monday:

  • July 25 to July 28
  • Aug. 1 to Aug. 4
  • Aug. 8 to Aug. 11
  • Aug. 15 to Aug. 18

The G line, which runs between Brooklyn and Queens without entering Manhattan, has seen major investments in recent years.

During last summer’s shutdowns, the MTA deep-cleaned 10 stations and replaced tiles, lighting and columns. Cell service is also expected to roll out in tunnels north of Hoyt-Schermerhorn by the fall. Riders have also started seeing the new open-gangway R211T trains on the line as part of a broader modernization effort slated to continue through at least 2027.
