I-481 functions as the eastern half of what would be a beltway around Syracuse and as a bypass for through traffic around downtown Syracuse, as well as a freeway/divided highway connecting Syracuse to Fulton and Oswego. The road was proposed as two separate highways: the portion south of the Thruway as I-281, and NY 481 as a relocation of NY 57 (which has since been decomissioned but is signed as CR 57).
