Spanning 570 miles across New York State, The Governor Thomas E. Dewey Thruway is one of the longest toll superhighway systems in the United States.
The Thruway's 426-mile mainline connects New York City and Buffalo, the state's two largest cities. The Thruway route from New York to the Pennsylvania line at Ripley is 496 miles long.
Other Thruway sections make direct connections with the Connecticut and Massachusetts turnpikes, New Jersey's Garden State Parkway and Interstate 287, and other major expressways that lead to New England, Canada, the Midwest and the South.
The Thruway includes Interstate 87 (New York City to Albany); Interstate 95 (New York City to Connecticut); Interstate 287 (connecting I-87 with I-95); Interstate 90 (both the Berkshire Spur, which connects I-87 with the Massachusetts Turnpike, and the mainline Thruway, which runs from Albany to the Pennsylvania border through Syracuse and Buffalo), and Interstate 190 (connecting Buffalo with Niagara Falls).
