Received the following advisory from the Roosevelt Island Operating Corp (RIOC):

PLEASE BE ADVISED THAT THERE WILL NOT BE ANY NORTHBOUND (QUEENSBOUND) F TRAIN SERVICE AT THE ROOSEVELT ISLAND STATION FOR THE WEEKENDS OF APRIL 9 – 11 and APRIL 23 – 25

RIOC will be providing 24-hour Tram service these weekends to minimize the inconvenience to Island residents.

There will be 2 Trams running continuously during the hours of 12 PM and 7 PM on Saturday and Sunday.

At all other times both Trams will run at 15 minute intervals.

Thank you for your cooperation….

Additional weekend F Train subway service disruption information available from the MTA.

… For service to Roosevelt Island and 21 St-Queensbridge, take the F to Roosevelt Av

and transfer to a Coney-Island bound F.

For service from 57 St, Lexington Av-63 St, Roosevelt Island and 21 St-Queensbridge,

take a Coney Island-bound F to 47-50 Sts and transfer to a Jamaica-bound F .

Also, since the F Train will be running on the M line , you can take the F to 53rd and Lexington. Then walk to the Tram on 2 Ave and 60th Street thereby avoiding the longer subway trip into Queens and back to Roosevelt Island.
