Bridges
The Hudson River itself can be both means of and impediment to travel. A few commuter ferry services exist in the lower valley, but bridges have otherwise become the dominant means of crossing the river. Tolls vary in cost, getting progressively more expensive closer to New York City. E-Z Pass electronic payment, common in the northeast United States, is accepted at all of the following Hudson River crossings with eastbound but not westbound tolls:
The New York State Bridge Authority (http://www.nysba.state.ny.us/) operates:
Rip Van Winkle - Catskill, Green County to Hudson, Columbia County
Kingston-Rhinecliff - Kingston, Ulster County to Rhinecliff, Dutchess County
Mid-Hudson - Highland, Ulster County to Poughkeepsie, Dutchess County
Newburgh-Beacon - Newburgh, Orange County and Beacon, Dutchess County
Bear Mountain - Bear Mountain, Orange County to Peekskill, Westchester County
The New York State Bridge Authority (http://www.thruway.ny.gov...) operates:
Tappan Zee - Nyack, Rockland County to Tarrytown, Westchester County
The Port Authority of New York and New Jersey operates:

Beeline Bus System
(http://www.beelinebus.com). Westchester county's bus system also connects to nearby lines, such as Rockland County (http://www.co.rockland.ny...) and Fairfield County, Connecticut (http://www.cttransit.com). Elsewhere in the Hudson Valley, public transit is either very poor Dutchess, Ulster, Putnam counties or near-nonexistent Orange, Sullivan, Columbia, Greene counties.
