The MTA's "Fastrack" maintenance program is coming to the F train this week.
Starting Monday night and for the next three nights, F service will be suspended in both directions between West 4th Street in Manhattan and Jay Street-Metrotech in Brooklyn.
The F will be rerouted along the A line between those two stations.
Free shuttle buses will provide alternate service, along with the D and J trains.
The work starts at 10 p.m. each night and runs until 5 a.m. the next day.
It's expected to wrap up on Friday.
