Iredell County is an important transportation center for the state, as both Interstate 77 and Interstate 40 cross just north of Statesville. This has given birth to the county's slogan "Crossroads for the Future." Residents have easy access south down I-77 to Charlotte, North Carolina, north to Elkin, North Carolina, and Roanoke, Virginia, east to Winston-Salem and Greensboro, and west along I-40 to Hickory, North Carolina, and Asheville.
Farming is still a major source of income for many Iredell County residents. Dairy farming has been particularly popular in Iredell County for centuries, in both the northern and southern sections of the county. However, the rapid population growth and development in southern Iredell County is putting increasing pressure on farmlands, and many farms in this section are giving way to shopping centers, housing developments, and large corporate office parks.
