 On April 1 , 1980 , ownership and maintenance of NY 380 's lone independent , state @-@ maintained portion from NY 424 to the east end of its overlap with US 20 was transferred from the state of New York to Chautauqua County as part of a highway maintenance swap between the two levels of government . The county also assumed maintenance of NY 424 , NY 428 , and two reference routes in Dunkirk and Fredonia in the swap . In exchange , the state received ownership and maintenance of NY 394 between US 20 and NY 5 in the town of Westfield , US 62 from NY 60 to NY 394 east of the city of Jamestown , and Forest Avenue from the Pennsylvania state line in Busti to NY 60 in Jamestown . Forest Avenue became NY <unk> , an unsigned reference route .
