Yet again, G train shutdowns are coming this summer—here's what to know

Brace yourselves, Greenpoint faithful: The “Summer of G” is back—and not in a fun, alphabet-themed beach towel kind of way.

Starting July 14 through Aug. 18, the G train will once again ghost riders between Court Square and Bedford-Nostrand Avenues on select weeknights and weekends. It’s all part of the MTA’s ongoing effort to drag the line’s Depression-era signals into the 21st century (1930s tech may be vintage-cool in fashion, but less so when you're stuck waiting in a dark tunnel).

There will be no G service between Court Square and Bedford-Nostrand from 9:45 p.m. to 5 a.m. on the following weeknights: July 14–18, July 24–25, Aug. 4–8 and Aug. 11–15. Weekend closures run from 9:45 p.m. Friday to 5 a.m. Monday on July 25–28, August 1–4, Aug. 8–11 and Aug. 15–18.

If your summer social calendar includes Williamsburg dive bars or a late-night taqueria run in Fort Greene, plan to pivot. The MTA is deploying fare-free shuttle buses that will stop at every affected station, running every 3–4 minutes overnight and every 5–10 minutes on weekends. G service will still operate south of Bedford-Nostrand down to Church Avenue.

It’s all part of a $368 million signal modernization project that’s installing CBTC (communications-based train control), which promises faster, more reliable trains once complete in 2027. This is the fourth phase of outages following last summer’s sweeping shutdowns, which came with a few silver linings: 10 stations got deep-cleaned, lighting and tile upgrades were installed and yes, 5G is on the way (expected this fall).

Even some of the new open-gangway R211T trains have begun rolling out on the G and when the CBTC is live, they’ll be fully compatible, so while the summer detours are annoying, they're also paving the way for a smoother ride.

For real-time updates, check the MTA app or sign up for alerts. And maybe start getting friendly with those shuttle bus stops now—just in case.
