MTA ferries from Glen Cove to Manhattan are scheduled to run until early September to provide alternatives to Long Island Rail Road commuters affected by reduced service into Penn Station this summer. The MTA this week released the ferry schedule for Glen Cove, with a 149-passenger ferry scheduled to depart Glen Cove for Wall Street at 6:10 a.m., and a 225-passenger ferry to 34th Street slated to leave Glen Cove at 6:35 a.m. The MTA is open to looking at schedule adjustments, based upon feedback from passengers, usage patterns and the availability of dock space in Manhattan, Donovan said. But, he said in a statement, additional boats are unlikely, because the agency “canvassed the ferry industry and secured the maximum capacity we could.” There are 108 parking spaces at the ferry terminal, Glen Cove Deputy Mayor Barbara Peebles said. In addition, RXR Glen Isle Partners, which is constructing a housing, commercial and recreational development adjacent to the ferry terminal, is grading and spreading gravel on two plots of land near the terminal for about 265 additional spaces, Frank Haftel, RXR’s director for the project, said. Work was ongoing Thursday and scheduled to be complete by Sunday, he said.
