It is also designated—but not signed—as State Route 401 (SR 401). In downtown Atlanta, I-75 joins with I-85 as the Downtown Connector. ==Route description== I-75 enters Georgia near Valdosta, and it continues northward through the towns of Tifton and Cordele until it reaches the Macon area, where it intersects with I-16 eastbound towards Savannah. For northbound traffic wishing to avoid potential congestion in Macon, I-475 provides a relatively straight bypass west of that city and I-75's route. After Macon it passes the small town of Forsyth. The freeway reaches no major junctions again until in the Atlanta metropolitan area. The first metropolitan freeway met is I-675, then followed by the Atlanta "Perimeter" bypass, I-285. It crosses inside the Perimeter and heads northeast several miles towards the Atlanta city center. I-75 then runs concurrently with I-85 due north over the Downtown Connector through the central business district of Atlanta. After the two Interstates split, I-75 makes a beeline northwest, crossing outside the I-285 Perimeter and heading towards the major suburban city of Marietta. This section of I-75 just north of I-285 has 15 through lanes, making it the widest roadway anywhere in the Interstate Highway System. North of Marietta, the final major junction in the Atlanta metropolitan area is the I-575 spur. I-75 then traverses the hilly northern Georgia terrain as it travels towards Chattanooga, Tennessee. The section of I-75 from I-475 to I-24 in Chattanooga is one of the longest continuous six-lane freeways in the United States (some segments along this corridor have as many as 16 lanes). Due to recent widening in south Georgia, the only four-lane section of I-75 in Georgia is bypassed by six-lane I-475; along this route there are at least six lanes from Florida's Turnpike in Wildwood, Florida to I-24 in Chattanooga. 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 75 in Georgia」の詳細全文を読む スポンサード リンク
