Commuters will soon see new exit signs along the Taconic State Parkway in Westchester County that are numbered based on the distance from the beginning of the parkway to each interchange, rather than in consecutive order. For example, the exit to State Routes 100 and 133 is now Exit 8, because it is eight miles from the start of the parkway at the traffic circle near the Kensico Dam Plaza in Westchester County, said New York State Department of Transportation Commissioner Matthew J. Driscoll.
