NEW YORK — As tunnel work continues, the MTA says it is adding some additional projects at some stations.
That will mean a service change this weekend and for a few weekends in October and November.
An escalator will be added at Union Square from the Mezzanine to the L train platform. Crews have to dig the pit and remove the rock.
The L train will not run between 8th Avenue in Manhattan to Broadway Junction in Brooklyn. It will run in Canarsie to Broadway Junction.
Two shuttle buses will service Brooklyn and connect to the G and M lines. Transit says additional M14 bus service will be running in Manhattan.
Regular service is scheduled to resume Monday morning around 5 a.m.
This is the largest weekend closure in awhile. The L train tunnel project began at the end of April to repair super storm damage in the structures connecting Brooklyn and Manhattan.
The L train has continued to run normally through two tracks during the weekday. During overnights and weekends, one track is worked on at a time which creates about a twenty minute wait for a train.
Next year, elevator projects will begin at 14th street-6th Avenue.
MTA statistics show The L platform at Union Square is among the most congested platforms in the system: 18,700 people use it in the AM peak hour and 16,500 in the PM.
The new escalator at Union Square will open in 2020.
