Interstate 75 (I-75) in the US state ofGeorgia travels north–south along theU.S. Route 41 (US 41) corridor in the central part of the state, traveling through the cities ofValdosta,Macon, andAtlanta. It is also designated—but not signed—asState Route 401 (SR 401).
I-75 is the only Interstate to traverse the full length of the state from north to south, from the flatAtlantic Coastal Plains insoutheast Georgia to the rollingmountains of North Georgia. InDowntown Atlanta, I-75runs concurrently withI-85 as theDowntown Connector. The segment fromSR 49 inByron toI-16 inMacon is part of theFall Line Freeway and may be incorporated into the eastern extension ofI-14, which is currently entirely withinCentral Texas and is proposed to be extended toAugusta.
What would become the general routing of I-75 in Georgia was initially used by the western routing of theDixie Highway beginning in 1916. Established in 1926, the Interstate's direct predecessor in Georgia is US 41, a national highway that has been largely supplanted in favor of the federally-funded freeway built under theInterstate Highway System—though limited-access elements of the Interstate existed as early as 1951.
With a length of 355.1 miles (571.5 km), I-75 is the longestInterstate Highway in Georgia.[1] It enters the state nearValdosta, and it continues northward through the towns ofTifton andCordele until it reaches theMacon area, where it intersects withI-16 eastbound towardSavannah. For northbound traffic,I-475 provides a relatively straight bypass west of that city and I-75's route.
After Macon, I-75 passes the small town ofForsyth. The freeway reaches no major junctions again until in theAtlanta metropolitan area. The first metropolitan freeway met isI-675, then followed by the Atlanta "Perimeter" bypass,I-285. It crosses inside the Perimeter and heads north several miles toward the Atlanta city center. I-75 thenruns concurrently withI-85 due north over theDowntown Connector through the central business district of Atlanta. The two Interstates intersectI-20 in downtown. Several miles north of the I-20 interchange, the two Interstates split, I-75 heads in a general northwest direction while I-85 heads northeast, crossing outside the I-285 Perimeter and heading toward the major suburban city ofMarietta. This section of I-75 just north of I-285 has 16 through lanes, making it the widest roadway anywhere in theInterstate Highway System.[4] North of Marietta, the final major junction in the Atlanta metropolitan area is theI-575 spur. I-75 then traverses the hillyNorth Georgia terrain as it travels towardChattanooga, Tennessee.
The 190-mile-long (310 km) section of I-75 from the northern I-475 intersection to theUS 11/US 64 intersection inOoltewah, Tennessee, is one of the longest continuous multi-state six-lane freeways in the US (some segments along this corridor have as many as 16 lanes).[citation needed]
Due to recent lane widening in southern Georgia completed in 2011,[5] 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 theAlligator Alley portion of I-75 inNaples, Florida, to a portion of I-75 in Ooltewah (except a four-lane overpass on I-475 over a railroad track in Macon).
I-75 is the only Interstate to traverse the full length of the state from north to south. The entire length of I-75 in Georgia is part of theNational Highway System, a system of routes determined to be the most important for the nation's economy, mobility, and defense.[6][7][8][9][10][11][12]
TheGeorgia Department of Transportation operates two welcome centers at both ends of Interstate 75 and nine rest areas, the most of any interstate highway within the state. The northbound welcome center is located between exits 2 and 5[13] The southbound welcome center is located between exits 353 and 350.[14] The other rest areas include two in Cook County, two in Turner County, two in Dooly County, one southbound rest area in Monroe County, and two in Gordon County.[15]

The general routing of I-75 within Georgia was originally developed as the western routing of theDixie Highway. The western route of the Dixie Highway as designated in 1916, followed present-day US 41 south from the Tennessee border through Atlanta and Macon south toEcheconnee, Georgia. The section that would become US 41, I-75's direct predecessor, from Echeconnee south through Perry and Valdosta to the border with Florida was paved beginning in 1919 and was later designated as a part of the Dixie Highway in 1924. In 1926, the western route of the Dixie Highway following the newer Perry and Valdosta route was officially designated as US 41. By October 1929, the majority of US 41 was paved in Georgia, the only sections that were not paved at that point were betweenFort Oglethorpe andRinggold, and another on the south side ofCalhoun.[16]
The highway that would eventually become I-75 in Georgia was an unnamed expressway that was open in 1951 from the southern part of Atlanta to University Avenue. It was projected from University Avenue to Williams Street in Downtown Atlanta. This expressway was open from Williams Street to what is now the northern end of the Downtown Connector. It was also proposed from the Downtown Connector to the northwest part of Atlanta.[17][18] By late 1953, this expressway was signed asUS 19/US 41 as far north as Lakewood Avenue. It was under construction from the Downtown Connector to Howell Mill Road. It was proposed from Howell Mill Road to the northwest part of Atlanta.[18][19] By mid-1954, the expressway was signed asSR 295 from Lakewood Avenue to University Avenue. It was under construction from the Downtown Connector to US 41/SR 3E, just north of West Paces Ferry Road.[19][20] By mid-1955, the highway was under construction from University Avenue to Glenn Street. It was open from Williams Street to US 41/SR 3E in the central part of Atlanta.[20][21] By mid-1957, the highway was opened from University Avenue to Glenn Street. It was also open from Williams Street to US 41/SR 3E in the northwest part of Atlanta.[21][22]
By the middle of 1960, a short segment southeast of Williams Street was open.[22][2] By mid-1963, I-75 was signed. It was open from the Florida state line to US 41/SR 7 inUnadilla. It was under construction from Unadilla to just north of theCrawford–Bibb county line. It was open fromSR 148 inBolingbroke toUS 23/SR 42 north-northwest of Forsyth. It was open from Glenn Street to Washington Street in Downtown Atlanta. It was under construction from US 41/SR 3 in the northwest part of Atlanta to its northern interchange with I-285. It was also under construction fromSR 53 in Calhoun to the Tennessee state line.[2][3] Between 1963 and 1965, it was open from US 41/SR 7 in Unadilla to Hartley Bridge Road south-southwest of Macon. It was proposed from Hartley Bridge Road to I-16 in Macon. It was under construction from I-16 to its northern interchange with I-475 near Bolingbroke. It was open from Bolingbroke to near Forsyth. It was under construction from there toSR 155 south ofMcDonough. It was proposed from there toSR 54 inMorrow. It was under construction from Morrow to US 19/US 41 west of Morrow. It was proposed from that interchange toSR 331 inForest Park. It was open from Forest Park to West Paces Ferry Road in northwest Atlanta. It was under construction from there toSR 120 inMarietta. It was proposed from Marietta toSR 140 inAdairsville. It was under construction from Adairsville to SR 53 in Calhoun. It was open from Calhoun to the Tennessee state line.[3][23] In 1966, the highway was open from the Florida state line to its southern interchange with I-475 near Macon. It was open from I-16 to US 23/SR 42 near Forsyth. It was open from Forest Park to its northern interchange with I-285.[23][24] In 1967, it was under construction fromUS 80/SR 74 to I-16 in Macon. It was under construction from near Forsyth to the US 19/US 41 interchange west of Morrow. It was open from Forest Park to SR 120 in Marietta. It was under construction from SR 120 to Allgood Road in Marietta.[24][25] In 1968, the highway was open US 23/SR 42 near Forsyth to SR 20 in McDonough. It was under construction from McDonough to SR 54 in Morrow. It was open from Morrow to Allgood Road in Marietta. It was under construction fromUS 411/SR 61 nearCartersville to SR 140 in Adairsville.[25][26] In 1969, the highway was under construction from its southern interchange with I-475 to I-16 in Macon. It was open from I-16 to Allgood Road in Marietta.[26][27]

In 1971, it was open from the Florida state line to Allgood Road in Marietta.[28][29] In 1973, it was under construction from Marietta to SR 92 inAcworth.[30][31] In 1974, the highway was under construction fromEmerson to US 411/SR 61 near Cartersville.[31][32] The last segment of I-75 in Georgia, located between Emerson and Cartersville, opened on December 21, 1977.[33][34]
Much of the work to widen interstates across Atlanta including I-75 from six to eight lanes and theDowntown Connector to 10 lanes including the elimination of sharp curves and grades, left-hand exits, excessive interchanges, and short acceleration/deceleration lanes, took place in the 1980s. Construction began with wideningI-285 first, beginning in 1976, continued to the radiating expressways, and concluded with the depressed sections of theDowntown Connector which were completed in 1988. I-75 widening from I-285 and Aviation Boulevard to theDowntown Connector was completed by late 1984. I-75 widening from the Brookwood Interchange to the Chattahoochee River and Cobb County line was widened in the early 1980s and completed by 1985. Work on theDowntown Connector portion began in 1984, and included redesigning the massive interchange between I-20 and I-75/I-85 and the design and construction of 55 bridges over the connector portion alone.[35] The project was completed in November 1988.

In addition to the general-purpose lanes added in the 1980s, provisions forhigh-occupancy vehicle lanes (HOV lanes) and dedicated onramps at Williams Street,Piedmont Avenue, and Memorial Drive were built and were subsequently converted to HOV usage in 1996 on theDowntown Connector. In 1996, HOV lanes were also added fromI-285 on the south side of Atlanta to I-285 on the north side of Atlanta.[citation needed]
In 1998, the portion of I-75 that from theChattahoochee River north to the Tennessee state line was named theLarry McDonald Memorial Highway.[36]Larry McDonald, a conservativeDemocratic representative toCongress, was aboardKorean Air Lines Flight 007 when it was shot down by theSoviet Union on September 1, 1983. He was the only sitting Congressperson to be reportedly killed by the Soviets during theCold War.[citation needed] I-75 was also designated as theHorace E. Tate Freeway between I-85 to I-285 northwest of Downtown Atlanta, in honor ofHorace Tate, who was astate senator in 1974.[when?][citation needed]
Until 2000, the state of Georgia used the sequential interchange numbering system on all of its Interstate Highways. The first exit on each highway would begin with the number "1" and increase numerically with each exit. In 2000, theGeorgia Department of Transportation (GDOT) switched to a mileage-based exit system, in which the exit number corresponded to the nearest milepost.[37][38]
In March 2007, I-75's HOV ramp serving Northside Drive in Atlanta was the site of theBluffton University bus crash where 7 out 35 people on board the bus were killed.[39]
The highway had a lane widening project completed in 2011, allowing the entirety of the Interstate in Georgia to be three lanes in each direction.[5] On January 28, 2017, the newPeach Pass-onlySouth Metro Express Lanes fromSR 155 toSR 138 and I-675, opened.[40] On September 8, 2018, newNorthwest Corridor Express Lanes from the I-285/I-75 interchange to Hickory Grove Road and from I-75/I-575 interchange to Sixes Road have opened, the lanes require a Peach Pass to use.[41]
The I-75/I-16 interchange is being revamped with extra ramps to and from US 23/US 129/SR 49.[42]GDOT estimates that the final portion of the project will be bid on in 2023.
The segment of I-75 from SR 49 inByron toI-16 inMacon is part of theFall Line Freeway and may be incorporated into the eastern extension ofI-14, which is currently entirely withinCentral Texas and is proposed to be extended toAugusta.[43]
Note: exit numbers along Georgia Interstates were renumbered in 1999 and 2000 to be mileage based instead of being sequential.[37][44]

There are threeauxiliary Interstate Highways related to I-75 in Georgia and a fourth that was proposed.I-175 was a proposed spur fromAlbany northeast toCordele. The road was built, but not as afreeway; it isSR 300, the Florida–Georgia Parkway.I-475 is a westernbypass ofMacon, shortening the trip for through I-75 traffic.I-575 is aspur from nearMarietta north toCanton andNelson, andI-675 is a cutoff from I-75 south ofAtlanta north toI-285 (Atlanta'sperimeter)—east of I-75.
Additionally, there are threebusiness routes of I-75 in the state. The firstI-75 Business Loop (I-75 BL) runs through centralValdosta mostly concurrent withUS 221.
