 A request by the state to dismiss the suit was denied in August 1966 , and the case was eventually heard by the state Court of Appeals , the highest court in the state . In the meantime , the state built the easternmost mile ( 1 @.@ 6 km ) of the new alignment , which was not affected by the lawsuit . On July 7 , 1967 , the court ruled 6 – 1 in favor of the Sleepy Hollow Valley Committee . As a result , the western half of the new road was moved an additional mile to the north , bypassing North Tarrytown completely . The new alignment of NY 117 was completed in the early 1970s , and its former alignment along Bedford Road was redesignated as NY 448 .
