Most of the county routes in Erie County, New York, act as primary roads in the less developed areas and also serve to interconnect the various villages and hamlets of the county. Not all routes are signed. All routes are maintained by the Erie County Department of Public Works, Division of Highways. The area has over 300 routes, due to the urbanizing of Erie County. Routes 250 through 511 all run in a general northeast–southwest pattern. No other patterns exist in Erie County.
The county route system in Erie County dates to 1916, designed to be a system to help connect future state highways in the county. The first nine county roads were assigned at that time.
