Interstate 520 (I-520) is a 23.34-mile (37.56 km) auxiliary Interstate Highway that encircles most of Augusta, Georgia and North Augusta, South Carolina as a three-quarter beltway around the western, southern, and eastern parts of the Augusta metropolitan area. It begins at I-20 in the northern part of Augusta, and ends at I-20 in the northern part of North Augusta, South Carolina. I-520 is also known as Bobby Jones Expressway and the Deputy James D. Paugh Memorial Highway in Georgia and Palmetto Parkway in South Carolina. In Georgia, the road also carries unsigned State Route 415.

I-520 begins at an interchange with I-20 (Carl Sanders Highway) in the northern part of Augusta. At this interchange, the roadway continues as Georgia State Route 232 (SR 232), which takes on the Bobby Jones Expressway name. The interstate travels to the south-southeast. After passing the Augusta Exchange shopping complex, east of Doctors Hospital, it has an interchange with Wheeler Road and Marks Church Road. After a slight western jog, I-520 continues to the south-southeast and meets Wrightsboro Road, which leads to the Augusta Mall. About 1 mile (1.6 km) later is an interchange with US 78/US 278/SR 10 (Gordon Highway). The freeway curves to the southeast, passing by Glenn Hills Middle School and Glenn Hills High School, to an interchange with US 1/SR 4 (Deans Bridge Road). It passes by a campus of Augusta Technical College and the Richmond County Technical Career Magnet School, before curving to the east-southeast and meeting an interchange with Windsor Spring Road and US 25/SR 121 (Peach Orchard Road). After a curve to the east is an interchange with SR 56 (Mike Padgett Highway), which is east of Southside Elementary School and northeast of East-Central Regional Hospital. I-520 curves to the east-northeast and has an interchange with Doug Barnard Parkway (formerly signed as SR 56 Spur). The interstate gradually curves to the northeast and has an interchange with Laney-Walker Boulevard and SR 28 (Sand Bar Ferry Road). Just over 1,000 feet (300 m) later, it crosses the Savannah River into South Carolina and the city limits of North Augusta. I-520 curves to the north-northwest, to an interchange with US 1/US 78/US 278 (only signed as "US 1"). The highway curves back to the north-northeast and has an interchange with South Carolina Highway 126 (SC 126; Clearwater Road). During a slight westward shift is an interchange with US 25/SC 121 (Edgefield Road). Just north-northeast of there, I-520 meets its eastern terminus, another interchange with I-20.

In Georgia, I-520 is known as Bobby Jones Expressway for professional golfer Bobby Jones; in South Carolina it is known as Palmetto Parkway for the sabal palmetto, the state tree. Between exits 2–3, the highway is known as the Deputy James D. Paugh Memorial Highway after a Richmond County sheriff's deputy who was killed at exit 3 when responding to reports of a gunman who was shooting at passing cars.[3] I-520 loses its state route designation in South Carolina, as that state does not co-number its interstates with state highway numbers.

History

The highway that would become I-520 was built between 1960 and 1963 between the intersection of SR 104 and SR 232 in Martinez roughly to the location of the current I-20/SR 232 interchange.[4][5] In 1965, this roadway was under construction from I-20 to just south of the US 1/SR 4 interchange in Augusta.[6][7] In 1966, the highway was open, and signed as SR 232, from I-20 to Wrightsboro Road. It was under construction from US 1/SR 4 to Doug Barnard Parkway.[7][8] In 1974, SR 232 was open from I-20 to US 1/SR 4.[9][10] In 1977, the highway was redesignated as I-520.[11][12] The next year, it was open from US 1/SR 4 to Doug Barnard Parkway.[12][13] In 1986, the highway was under construction from Doug Barnard Parkway to SR 28.[14][15] In 1998, this segment was opened.[16][17] The next year, it was proposed to be extended to the South Carolina state line.[17][18] In 2001, this proposal was extended to US 1/US 78/US 278 in North Augusta.[19][20] In 2004, this extension was opened.[21][22] In 2010, the highway was extended to its current eastern terminus in the northern part of North Augusta.[23][24]

In January 2015, 4.7 miles (7.6 km) of I-520 were expanded to three lanes after starting work in February 2012 for a cost of $33 million.[25]
