Part of the M subway line will shut down for months next year, the MTA confirmed Thursday.
The shutdown, which is for repairs, will be completed before the anticipated L train shutdown in 2018.
M trains runs through Queens, Manhattan and Brooklyn.
The shutdown affects riders in Queens and Brooklyn between the Metropolitan Avenue stop in Middle Village and the Myrtle Avenue stop in Bushwick.
The shutdown will affect thousands of riders commuting to and from Manhattan.
Commuters on the Metropolitan Avenue, Fresh Pond Road, Forest Avenue and Seneca Avenue stops will be left in the lurch, as there are no other subway lines nearby.
In January, about 150 Brooklynites told MTA officials that they believe businesses will shutter and people will lose their jobs if the L train is shut down for more than a year to make repairs to the Canarsie Tube, which was damaged heavily during Sandy.
