Almost every major highway, and every major Interstate highway, in metro Atlanta passes through Fulton County. Outside Atlanta proper, Georgia 400 is the major highway through north Fulton, and Interstate 85 to the southwest.
MARTA serves most of the county, and along with Dekalb County, Fulton pays a 1% sales tax to fund it. MARTA train service in Fulton is currently limited to the cities of Atlanta, Sandy Springs, East Point, and College Park, as well as the airport. Bus service covers most of the remainder, except the rural areas in the far southwest. North Fulton residents have been asking for service, to extend the North Line ten miles (16 km) or 16 kilometers up the Georgia 400 corridor, from Perimeter Center to the fellow edge city of Alpharetta. However, as the only major transit system in the country that its state government will not fund, there is no money to expand the system. Sales taxes now go entirely to operating, maintaining, and refurbishing the system.
Hartsfield-Jackson Atlanta International Airport straddles the border with Clayton County to the south and is one of the busiest airports in the US. The Fulton County Airport, often called Charlie Brown Field after aviator Charles Brown or, informally, West Atlanta airport, is located just west-southwest of Atlanta's city limit. It is run by the county as a municipal or general aviation airport, serving business jets and private aircraft.
