No Manhattan bound F Trains from Roosevelt Island this weekend. According to the MTA:

Manhattan-bound trains run on the V from Roosevelt Av to 47-50 Sts
Weekend, Mar 15 – 17, 12:01 AM Sat to 5 AM Mon

How does this affect my trip?
Trains skip 21 St-Queensbridge, Roosevelt Island, Lexington Av-63 St, and 57 St.

For service to these stations, take the F to 47-50 Sts and transfer to a Queens-bound F.

For service from these stations, take a Queens-bound F to Roosevelt Av and transfer to a Manhattan-bound F.

Why is service being changed?
We are making electrical improvements to ensure that trains continue
to operate safely along the F line.

I guess Southbound means towards Manhattan and vice versa.
