Option 4D
Alternatives 4A, B, and C feature a Commuter Rail Transit (CRT) system in Rockland County in addition to a new bridge and highway improvements (climbing lanes, HOT lanes) in Rockland County similar to those in Alternative 3.
The commuter rail would branch off Metro-North’s Port Jervis Line and travel across the bridge to a new Tappan Zee station in Tarrytown, with a one-seat ride down the Hudson Line to Grand Central Terminal. These three alternatives vary as they cross Westchester County.
Option 4D, a variation of Alternative 4C, would provide commuter rail transit service between Suffern and Grand Central Terminal in Manhattan as well as bus rapid transit service between Suffern and Port Chester, serving both the cross-corridor and the New York City market. The commuter rail service would begin in Suffern with a direct connection to the Port Jervis Line and connect into the Hudson Line for a one-seat ride to Grand Central Terminal in Manhattan. The bus rapid transit service would begin in Suffern across Rockland County along I-287 and continue through Westchester County to Port Chester as in Option 3A with transfer capability to the Harlem and New Haven Lines.
