[[File:Fix&amp;Fortify - Greenpoint Tubes (9504656210).jpg|thumb|Repairs of the Greenpoint Tubes from Hurricane Sandy]]
In 2012, flood waters from [[Hurricane Sandy]] caused significant damage to the Greenpoint Tubes under the [[Newtown Creek]]. Although the G was back in service days after the hurricane, the tube needed permanent repairs. To allow for these repairs, G service was curtailed for twelve weekends between July and December 2013, as well as daily between July 25 and September 2, 2014.<ref name="mta.info">{{cite web|title=G Line Review |website=mta.info |url=http://web.mta.info/nyct/service/G_LineReview.htm |access-date=October 29, 2015 |url-status=live |archive-url=https://web.archive.org/web/20151107094934/http://web.mta.info/nyct/service/G_LineReview.htm |archive-date=November 7, 2015 }}</ref>

The 2015–2019 [[Metropolitan Transportation Authority|MTA]] Capital Plan called for the Crosstown Line's [[Classon Avenue (IND Crosstown Line)|Classon Avenue]] and [[Flushing Avenue (IND Crosstown Line)|Flushing Avenue]] stations, along with 31 others, to undergo a complete overhaul as part of the [[Enhanced Station Initiative]]. Updates would include cellular service, Wi-Fi, USB charging stations, interactive service advisories and maps, improved signage, and improved station lighting.<ref>{{cite web|last=Whitford|first=Emma|date=January 8, 2016|url=http://gothamist.com/2016/01/08/subway_facelift_shutdown.php|title=MTA Will Completely Close 30 Subway Stations For Months-Long "Revamp"|publisher=Gothamist|access-date=July 18, 2016|url-status=dead|archive-url=https://web.archive.org/web/20160801200338/http://gothamist.com/2016/01/08/subway_facelift_shutdown.php|archive-date=August 1, 2016}}</ref><ref>{{Cite web|url=https://www.governor.ny.gov/sites/governor.ny.gov/files/atoms/files/MTAStations.pdf|title=MTAStations|website=governor.ny.gov|publisher=Government of the State of New York|access-date=July 18, 2016}}</ref> However, in April 2018, it was announced that cost overruns had forced the MTA to reduce the number of subway stations included in the program from 33 stations to 20.

====CBTC installation====
The MTA announced in early 2022 that it planned to put the contract to install [[communications-based train control]] (CBTC) on the Crosstown Line to [[Hoyt–Schermerhorn Streets station]] and modify the three interlockings on the line up for bid. The cost of the project is estimated to be $556.4 million.<ref>{{Cite web |date=February 18, 2022 |title=MTA 2022 Adopted Budget February Financial Plan 2022 – 2025 February 2022 |url=https://new.mta.info/document/76706#page=91 |access-date=July 14, 2022 |website=mta.info |publisher=Metropolitan Transportation Authority |page=V-3}}</ref> On May 16, 2022, the MTA put out the RFP for the design-build contract to install CBTC on the Crosstown Line. Court Square Interlocking will be modified to interface with CBTC while mechanical interlockings at Nostrand Avenue and Nassau Avenue will be replaced. Relay rooms and towers at Nostrand Avenue and Nassau Avenue will be decommissioned as part of the project. This project will include the use of axle counters instead of track circuits. Work on the project is expected to take four years.<ref>{{Cite web |date=May 16, 2022 |title=Solicitation Title: S48012 Design-Build Services for Communication Based Train Control Crosstown Line "B" Division in Brooklyn and Queens |url=https://new.mta.info/document/87291 |access-date=July 14, 2022 |website=mta.info |publisher=Metropolitan Transportation Authority}}</ref> In December 2022, the MTA announced that it would award a $368 million [[design–build]] contract to Crosstown Partners, a joint venture between Thales Group and TC Electric LLC.<ref name="Brachfeld 2022">{{cite web |last=Brachfeld |first=Ben |date=December 20, 2022 |title=MTA set to award $368 million contract to modernize G line signals |url=https://www.amny.com/transit/mta-contract-modernize-g-line-signals/ |access-date=December 21, 2022 |website=amNewYork}}</ref><ref name="dec22cpoc">{{Cite web |date=Dec 19, 2022 |title=Capital Program Oversight Committee Meeting December 2022 |url=https://new.mta.info/document/102776 |access-date=July 14, 2022 |website=mta.info |publisher=Metropolitan Transportation Authority |pages=99–101}}</ref> The contract includes not only the Crosstown Line between Court Square and Bergen Street, but also the Culver Line between Bergen Street and Church Avenue.<ref name="dec22cpoc" /> The project also included adding [[Passenger Wi-Fi on subway trains|Wi-Fi in the tunnels]].<ref>{{cite web | last=Burkett | first=N.J. | title=Exclusive look at MTA's G train modernization and what it means for riders in New York City | website=ABC7 New York | date=August 7, 2024 | url=https://abc7ny.com/post/exclusive-look-mtas-train-modernization-what-means-riders-new-york-city/15153632/ | access-date=August 8, 2024}}</ref>
