Preliminary Alternative 4B
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.
Alternative 4B would construct a new Light Rail System (LRT) between the new Tappan Zee commuter rail station and Port Chester.
