New York State Route 204 (NY 204) is an east–west state highway located just southwest of Rochester in Monroe County, New York, in the United States. The western terminus of the route is at exit 6 on Interstate 490 (I-490) in Gates. Its eastern terminus is at I-390 exit 18. The western portion of NY 204 is a limited-access highway known as the Airport Expressway that indirectly connects I-490 to the Greater Rochester International Airport. The remaining part of the connection is made by an at-grade portion of NY 204 on Chili (NY 33A) and Brooks Avenues. NY 204 was assigned c. 1965 from I-490 to the Rochester city line in Gates, however the section between I-390 and the city line was removed by January 2017.
