The Roosevelt Island Operating Corp ( RIOC ) adds:
While we continue to follow social distancing and align our operations with
New York Forward guidance, we also continue to incrementally increase the
number of passengers permitted on the Tram. Tram capacity will increase on
Monday, March 8th, from 35 to 55 passengers per cabin, and we will continue to
assess and gradually increase ridership in phases. We understand the need for
this mode of transportation, however, the health and safety of our riders and
operators are our priority. We appreciate your cooperation.
