Автомагистраль 520 штата Джорджия: от границы Алабамы до острова Джайл

Highway in Georgia
the current state highway

State Route 520 (SR 520), also known as the South Georgia Parkway, is a 261 mile (420 km) state highway in the southern part of the U. S. state of Georgia. It travels from the Alabama state line at the Chattahoochee River, along the Phenix City, Alabama–Columbus, Georgia line, to Jekyll Island. It has many concurrencies along its path, including U. S. 280 from the Alabama state line to Richland; US 27 from Columbus to Cusseta; and especially US 82 from Dawson to a point southwest of Brunswick. Also, all of GA 520 is Corridor Z, a high priority corridor to the Coastal Georgia Regional Development Center and a GRIP (Governor's Road Improvement Program) corridor, but not an Appalachian Regional Development highway, despite its green shield.

SR 520 begins at the Alabama state line concurrent with US 280. On the Alabama side of the state line, US 280 is concurrent with unsigned Alabama State Route 38. On the Georgia side of the state line, US 280/SR 520 head east through Columbus to an intersection with US 27/SR 1. The four highways head east through the city, along Victory Drive to an interchange with Interstate 185 (I 185), and through Fort Benning. Southeast of Fort Benning, the four highways have an intersection with SR 26 just prior to entering Cusseta. In town, US 27/SR 1 split from the concurrency, toward Lumpkin, while US 280/SR 520 head southeast to Richland. Here, the two highways intersect SR 27, with US 280 heading east along SR 27. SR 520 heads southeast alone, intersecting SR 41 in Weston, before reaching Dawson. In Dawson, there is an intersection with SR 45, which begins a short concurrency with SR 520. A short distance later is an intersection with SR 32, followed by US 82/SR 45/SR 50, where the concurrency with SR 45 ends and the one with US 82 begins. Just before leaving town, US 82/SR 520 intersect SR 55. The two highways head east until they reach Albany.

The roadway that would eventually become SR 520 was established in 1920 as SR 1 from Columbus to Cusseta, SR 32 from Dawson to Sylvester, and SR 46 from Sylvester to Tifton. In 1921, SR 55 was established along a route from Louvale, at an intersection with SR 1 to Dawson, and SR 50 was established along a stretch of highway from Dawson in the west, to at least as far as Waynesville, at an intersection with SR 27, in the east. Nearly all of SR 55, and all of that stretch of SR 50, were eventually utilized by SR 520. By 1926, a portion of SR 1 southeast of Columbus and a portion of SR 50 west of Sylvester were paved. Also, US 84 was designated along the portion of SR 50 east of Waycross. Sometime around 1926, SR 27 was redesignated as SR 25. By January 1932, US 280 was designated along SR 1 from Columbus to Cusseta and SR 55 from Cusseta to Richland. All of US 280/SR 1 and nearly all of US 280/SR 55 were paved. Also, a portion of SR 55 northwest of Dawson was paved. Almost all of SR 50 from Dawson to Tifton was paved, along with a portion west of Waycross, and the entirety of US 84/SR 50 east of the city. During October of that year all of US 280/SR 55 was paved. By May 1933, a portion of SR 55 between Alapaha and Willacoochee was paved. In June, a small portion of SR 55 southeast of Richland was paved. By October 1934, a portion of SR 50 east of Tifton, as well as one west of Alapaha, was paved. By January 1935, US 27 was designated along US 280/SR 1 from Columbus to Cusseta. By October 1935, all of SR 55 between Richland and Dawson was paved. By July 1936, all of SR 50 from Tifton to Willacoochee was paved. Also, nearly all of SR 50 east of Pearson was paved. By July 1937, all of the highway that would eventually become SR 520 between Columbus and Willacoochee was paved. By October 1939, the last pieces of the highway were paved. In 1948, US 82 entered the state, running concurrent with SR 50 only as far east as Waycross. In addition, SR 50 was extended, and paved, east to Jekyll Island.

In 1988, SR 520 was designated along its entire current length, with SR 55 between Richland and Dawson and SR 50 from Dawson to Jekyll Island being decommissioned. On May 5, 2006, the American Association of State Highway and Transportation Officials (AASHTO) Special Committee on U. S. Route Numbering designated the portion of SR 520 east of US 17 as Interstate 50 for one day, May 7. AASHTO held their Spring 2006 meeting on Jekyll Island and approved the I 50 designation in conjunction with a vintage car ride to be held on May 7 in celebration of the 50th anniversary of the Interstate Highway System.

State Route 520 Business (SR 520 Bus.) is a business route of SR 520 that exists almost entirely within the city limits of Albany. It follows North Slappey Boulevard and East Oglethorpe Boulevard through the city, and Sylvester Road east of the city. SR 520 Bus. travels entirely concurrently with US 82 Bus. and also has a concurrency with both US 19 Bus. and, briefly, with SR 234.
