In the U.S. state of Georgia, Interstate 20 (I-20) travels from the Alabama state line to the Savannah River, which the Georgia–South Carolina state line straddles. The highway enters the state near Tallapoosa. It travels through the Atlanta metropolitan area and exits the state in Augusta. The highway also travels through the cities of Douglasville, Covington, and Thomson. I-20 has the unsigned state highway designation of State Route 402. ==Route description== I-20 is four lanes wide in much of the state. In the Atlanta metropolitan area, the highway ranges from six lanes wide in the most outlying counties to 10 lanes wide in downtown Atlanta. I-20 enters the Peach State near Tallapoosa and after traveling through Western Georgia, it enters the Atlanta metropolitan area. On clear days, eastbound motorists get their first view of downtown Atlanta as they crest the top of Six Flags Hill. The Six Flags Over Georgia amusement park is easily visible off exit 47 eastbound. In Atlanta, the highway travels through the heart of the city, crossing I-75/I-85, which share a common expressway (the "Downtown Connector"). It continues though Metropolitan Atlanta eastward and through the eastern half of Georgia until it exits the state, crossing the Savannah River at Augusta. Several stretches of I-20 are named for various people and reasons: * From the Alabama state line to I-285 on the west side of Atlanta, I-20 is named the Tom Murphy Freeway, after the former speaker of the Georgia House of Representatives. * Between both the west and east sides of I-285, I-20 was named the Ralph David Abernathy Freeway in 1991 after the late civil rights activist. * From I-285 in Dekalb County to US 129/US 441/SR 24 south of Madison, I-20 is named the Purple Heart Highway for military veterans who either died or were injured in combat while in service on or after April 15, 1917. * Between US 129/US 441/SR 24 and the South Carolina state line, I-20 is named the Carl Sanders Highway after the former Georgia governor who was born in Augusta. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Interstate 20 in Georgia」の詳細全文を読む スポンサード リンク
