 Several different routes were considered for the alignment . The path ultimately selected by the state was a four @-@ lane , limited @-@ access highway 1 mile ( 1 @.@ 6 km ) north of the current alignment that would cost $ 5 @.@ 5 million ( 1966 USD ) . Another proposed route would have cost $ 8 million ( 1966 USD ) , containing additional grades and curves while coming closer to the Rockefeller estate . Construction on the new NY 117 was expected to begin before the end of 1966 . The reaction from area residents was mixed , with some believing that the only beneficiaries of a realigned NY 117 was the Rockefeller family . <unk> that the Rockefeller family had wanted NY 117 moved had existed as early as the 1930s , and US Representative Richard <unk> believed that Nelson Rockefeller , then the Governor of New York , was using his political power to move NY 117 away from Kykuit at the cost of the state . An aide to the <unk> denied this charge .
