To prepare for the revised project, which Governor Andrew Cuomo announced in the eleventh hour earlier this month, the MTA will be conducting improvement work in the coming weeks.
The work includes removing and replacing all 16,000 feet of rails, relocating and replacing cables, rebuilding Bedford Avenue switches and preparing key signals.
The MTA requires full service closures because they will use “specialized track equipment that needs full-track access.”
“For you, this means our track will be safer and trains will run faster and smoother,” the MTA said in a release, “and that we’ll have the right signals to run the one-track operation come April.”
But for L train riders, this means weeknight and weekend service will be largely disrupted between February and April.
From January 28 to March 18, between 10:45 p.m. and 5 a.m. on weeknights, the L train will not run between Broadway Junction in Brooklyn and 8th Avenue in Manhattan.
For customers traveling between Brooklyn and Manhattan, the MTA suggests taking the A, F, J or M trains instead. In Manhattan, take the M14 bus.
In Brooklyn, the MTA is running free shuttle buses that will stop at L train stations between Bedford Avenue and Broadway Junction.
The first bus route is between Broadway Junction and Lorimer Street, and will connect with the Marcy Avenue J train station.
The second route is a loop between the Marcy Avenue J stop, Hewes Street on the J, the Broadway station on the G line, Lorimer Street-Metropolitan Avenue on the G and Bedford Avenue.
L train service is also shut down every weekend, from February 1 to March 18, between Broadway Junction and 8th Avenue. The L will run between Broadway Junction and Rockaway Parkway in Canarsie.
The MTA will operate three shuttle bus routes, including a bus between Myrtle Avenue-Wyckoff Avenue on the M train and Lorimer Street on the G train.
The new L train tunnel repair project is expected to take 15 to 20 months. During the project, the L will run on one track on nights and weekends, but rush hour service is not expected to be impacted.
