U.S. Route 1 in Georgia

U.S. Highway 1 (US 1) in the U.S. state of Georgia, which is concurrent for almost its entire length with State Route 4 (SR 4), is a highway traversing south–north through portions of Charlton, Ware, Bacon, Appling, Toombs, Emanuel, Jefferson, and Richmond counties in the southeastern and east-central parts of the state. In Georgia, the highway originates at US 1/US 23/US 301/State Road 15 (SR 15) at the St. Marys River and the Florida state line, where SR 4 reach their southern terminus. It travels to the Savannah River at the South Carolina state line in Augusta where the route continues to North Augusta, South Carolina. Here, SR 10 reaches its eastern terminus.

National Highway System
The entire length of US 1 is part of the National Highway System, a system of routes determined to be the most important for the nation's economy, mobility, and defense.

1920s
The roadway that would eventually become US 1/SR 4 was designated at least as early as 1919 as part of SR 15 from the Florida state line to Alma, an unnumbered road from Alma to Baxley, part of SR 17 from Swainsboro to Louisville, and another unnumbered road from Louisville to Augusta. By the end of 1921, SR 32 was proposed on the Alma–Baxley segment. SR 17 was proposed on the Baxley–Swainsboro segment. The portion of SR 24 east of Louisville was shifted northwestward on the previously unnumbered road from Louisville to Augusta. Also, the portion of SR 17 north of Louisville was shifted eastward onto that same road from Louisville to Wrens. By the end of 1926, US 1 was designated on the entire Florida-to-Augusta path. SR 32 was designated from a point north-northeast of Alma to Lyons. SR 17 was designated from Baxley to Wrens. US 78/SR 10/SR 12 was designated from a point west-southwest of Augusta into that city. Three segments of US 1 had a "completed hard surface": a segment south-southeast of the Charlton–Brantley county line, from a point southeast of Waycross into that city, and from a point southwest of Augusta into that city. Two segments had a "completed semi hard surface": from the Florida state line to a point south-southeast of the Charlton–Brantley county line and from just south-southeast of this county line to southeast of Waycross. Two segments had a "sand clay or top soil" surface: from just south of the Ware–Bacon county line to Alma and from the Emanuel–Jefferson county line to Louisville. Four segments were indicated to be under construction: from Waycross to just south of the Ware–Bacon county line, from Alma to Baxley, from Swainsboro to the Emanuel–Jefferson county line, and from Louisville to southwest of Augusta. By the end of 1929, SR 4 was designated from Florida to Augusta. SR 32 was truncated off of US 1 at Alma. SR 24's portion east of Louisville was shifted back to its former routing, off of US 1. SR 17 was truncated off of US 1 at Wrens.

1930s and 1940s
By the middle of 1930, SR 15 was truncated to a point north-northeast of Alma. The entire highway, from the Florida state line to Augusta, had a completed hard surface. In January 1932, SR 17 was placed on a concurrency with US 1/SR 4 from Louisville to a point about halfway between Louisville and Wrens. In 1937, the entire segment from the Florida state line to Waycross was indicated to be under construction. By the end of the year, US 1/US 78/SR 4/SR 10/SR 12 were indicated to have entered the main part of Augusta on Milledgeville Road; they intersected US 25/SR 121 (Savannah Road); all seven highways traveled on Twiggs Street and 7th Street to an intersection with SR 28 (Broad Street); US 1/US 78/SR 4/SR 10/SR 12/SR 28 traveled east-southeast on Broad Street to an intersection with 5th Street; and US 1/US 78/SR 4/SR 10/SR 12 traveled on 5th Street to the South Carolina state line. By the end of 1939, SR 57 was placed on a concurrency with US 1/SR 4 from north of Oak Park to Swainsboro. In 1940, the northern end of the SR 17 concurrency was shifted northward to Wrens. By February 1948, US 301 was placed on a concurrency from the Florida state line to Folkston.

1950s
By August 1950, US 23 was placed on a concurrency from the Florida state line to a point north of Alma. Between September 1953 and June 1954, US 221 was placed on a concurrency from Louisville to Wrens. By June 1955, Gordon Highway was established around the southwest side of Augusta and proposed to the 5th Street/Gwinnett Street intersection. It began on US 78/SR 10/SR 12 (with US 278 newly designated on it) west-southwest of Augusta to US 25/SR 121 south of the city. No numbered highways were indicated to be designated on it, so US 1/SR 4 remained on its previous path. It had an interchange with US 25/SR 21. US 1/US 78/SR 4/SR 10/SR 12 split off of the US 78/US 278/SR 10/SR 12 concurrency just north-northeast of Gwinnett Street, where US 278 reached its eastern terminus. It traveled north-northeast to Calhoun Street, east-southeast to 5th Street, and resumed its 5th Street path, albeit on a more southern starting point. By the middle of 1957, Gordon Highway was completed around the southern and eastern sides of Augusta to 5th Street just north-northeast of Gwinnett Street in the city. US 1/US 25/US 78/US 278 was shifted onto the highway, with SR 4/SR 12 and possibly SR 10 remaining on Milledgeville Road, Twiggs Street, 7th Street, and Broad Street.

1960s
By June 1960, SR 15 was shifted eastward, onto a completely different alignment. It had two different concurrencies with US 1/SR 4: from the Florida state line to Racepond and from Baxley to South Thompson. In Augusta, SR 10 was shifted off of SR 4 and onto Gordon Highway. SR 21 was extended onto the SR 4/SR 12 concurrency on Twiggs Street and 7th Street. SR 21 reached its northern terminus at Broad Street. US 25 was shifted off of Broad Street and onto Gordon Highway, which was extended to the South Carolina state line. Its former path was redesignated as part of US 25 Bus. By June 1963, SR 121 was placed on a concurrency from Folkston to Racepond. By the end of 1965, a western bypass of Waycross was built from US 82/SR 50 west-northwest of the city to US 1/US 23/SR 4 northwest of it. SR 21 was extended west-northwest on US 25 Bus./SR 28 (Broad Street) and followed the business route to the South Carolina state line. SR 121 was extended on Gordon Highway from the US 25/SR 21/SR 121 interchange to the state line. Also, the intersection of Gordon Highway and Broad Street was converted into an interchange.

1970s to present
In 1976, SR 4 Spur was extended around the southwestern and southern edges of Alma to US 1/SR 4 in the southern part of the city. In 1978, a southern bypass of Waycross, designated as SR 714, was established with a "topsoil or gravel" surface from SR 122 west-southwest of the city to US 84/SR 38 southwest of it. It was also proposed from that intersection southeast, east, and northeast to US 1/US 23/SR 4 east-southeast of the city. In 1980, SR 4 Spur was redesignated as SR 4 Alt. The next year, SR 12's eastern terminus was truncated to Thomson. SR 21's northern terminus was truncated to Millen. SR 4's Milledgeville Road portion was truncated to the 15th Street intersection. It was routed on 15th Street and Walton Way and then resumed its 13th Street path, just with a more southerly starting point. In 1982, SR 714 was proposed to be extended west-northwest just north of the path of US 82/SR 50. In 1985, US 82/SR 50 through Waycross were rerouted, replacing all of SR 714's actual and proposed segments. In 1992, a western bypass of Waycross, designated as SR 896, was proposed from US 82/SR 520 west-northwest of the city to US 1/US 23/SR 4 northwest of it. In 1996, US 1/US 23/SR 4 was rerouted in the southern part of Waycross and north-northwest on the path of SR 896. Their former path became US 1 Bus./US 23 Bus./SR 4 Bus. In 2003, a western bypass of Swainsboro was proposed. The next year, US 1/SR 4 was shifted onto this bypass. Their former path through the city became US 1 Bus./SR 4 Bus.

Future
The portion from the southern part of Wrens to the central part of Augusta is part of the Fall Line Freeway, a highway that connects Columbus and Augusta. This portion may eventually be incorporated into the proposed eastern extension of I-14, which is currently entirely within Central Texas and may be extended into Augusta.

Widening project (Wadley to Wrens)
The Georgia Department of Transportation (GDOT) will widen 21 mi of US 1/SR 4 from north of Wadley to Wrens and will be a total of $17 million in budget. This project will widen US 1/SR 4 from two lanes to a four-lane road (each having 11 ft in width). Currently, GDOT has an ongoing plan to widen all of US 1/SR 4 to four lanes (with bypasses) with more than half of it complete. In a few years, it will be complete, and they will move on to the next phase. This project will be completed on September 30, 2022.

State Route 4
SR 4 is completely concurrent with US 1 from the Florida state line to the main part of Augusta. There, it is one of the main highways through the Medical District. It provides access to T. W. Josey High School, Paine College, the Medical College of Georgia, Augusta University Medical Center, the VA Medical Center, the Augusta University Annex building, and John S. Davidson Fine Arts Magnet School. It helps connect downtown Augusta with the western part of North Augusta, South Carolina.
