The FASTRACK maintenance program completely suspends train service over a segment of a subway line to give workers uninterrupted access to tracks, signals, cables, lighting, third rail components and platform edges.
J trains will end at the Delancey Street-Essex Street station. That means there will be no service between Bowery and Broad street.
You can take the F, 4 or 6 trains as alternatives.
The work will begin at 10 p.m. and last until 5 a.m. through Friday.
