Proponents say this plan, proposed by Richard Duffy of the Empire State Passenger Association, would help reduce traffic congestion by reducing bus riders' commute time (and attracting new riders in the process) and removing dozens of buses from Tarrytown's streets.

A range of other traffic reduction options are also being considered by the Task Force, including another span across the Hudson, improved ferry service, a light rail network, and congestion relief pricing. Minus the additional bridge construction, all of these demand management alternatives need should be implemented to encourage the Tappan Zee's 7,000 rush-hour users to switch travel time, carpool, or use mass transit.
