The route was assigned as part of the 1930 renumbering of state highways in New York . Although it began in Youngstown and ended in Newstead as it does today , the initial routing of NY 93 deviated from the modern path in the vicinity of the city of Lockport . From Cambria to Lockport 's eastern suburbs , the highway originally used NY 425 , Lower Mountain Road , Akron Road , and a series of streets in Lockport . NY 93 was moved onto NY 104 and Junction Road in Cambria in the 1940s , and altered to bypass Lockport to the south on a new highway and Robinson and Dysinger roads in 1991 . In 2006 , NY 93 was realigned west of Lockport to continue south on Junction Road to NY 31 . The change removed NY 93 from Upper Mountain Road , a county @-@ owned highway that had been part of the route since the 1930s .
