Did the MTA really have to schedule work on the July 4 weekend?

According to the Roosevelt Island Operating Corp (RIOC):

The MTA has issued a weekend service advisory for the F train, which may affect travel plans. The Tram will run on a rush hour schedule from 7:00 AM until 10:00 PM to accommodate any increase in traffic. Please plan your travel accordingly and visit mta.info/weekender or call 511 for more information.
