State Route 21 (SR 21) is an {{convert|84.4|mi|km|adj=mid|-long}} state highway that travels southeast-to-northwest through portions of Chatham, Effingham, Screven, and Jenkins counties in the eastern part of the U.S. state of Georgia. The highway connects the Savannah and Millen areas, via Garden City, Port Wentworth, Rincon, Springfield, and Sylvania.

SR 21 formerly had its northern terminus at the South Carolina state line in Augusta. It traveled on the current path of US 25/SR 121 from Millen to Augusta. In the city, it used the path of SR 28 (Broad Street) and the Georgia segment of US 25 Bus.

The highway is part of the Savannah River Parkway which is being considered for inclusion into Interstate 3 (I-3), a future Interstate Highway proposed to connect the Savannah and Knoxville, Tennessee areas.

Route description

SR 21 begins at an intersection with SR 204 (Abercorn Street) in Savannah. The highway travels to the west-northwest, becoming a freeway, and gains the designation of Interstate 516 (I-516) and the unsigned SR 421. The highways travel concurrently to the west-northwest, then curve to the north-northeast at the interchange with Veterans Parkway. At exit 3, US 17/SR 25 join the freeway from the southwest, and US 80/SR 26 join the freeway from the northeast. Continuing to the north-northeast, the highways have an interchange with I-16, at which point, US 17 departs to the east-southeast, concurrent with I-16. At exit 7, US 80/SR 26 depart to the west-northwest, and the highways turn to the west-northwest. After SR 25 departs, I-516/SR 421 ends, and SR 21 continues its northwestward route. In Port Wentworth, SR 30 joins the highway; north of their interchange with I-95, SR 30 departs to the west-southwest.

SR 21 continues north, leaving Chatham County and entering Effingham County. The highway travels through Rincon and Springfield, then continues northwest, through rural parts of the county, and continues into Screven County. After a brief concurrency with US 301/SR 73 Loop around the western side of Sylvania, SR 21 continues west into Jenkins County. East of Millen, SR 21 turns to the northwest at its intersection with SR 67, then arcs to the northeast of Millen to meet its northern terminus at US 25/SR 121.

Tom Triplett Parkway

The Tom Triplett Parkway is a section of SR 21 located in Port Wentworth on the west side of the Savannah metropolitan area.^[3]

It stretches from the Chatham–Effingham county line (roughly the Lake Cherie Road intersection) to the Garden City–Port Wentworth city line (roughly the SR 307 intersection).

In 2000, the Georgia General Assembly passed a resolution^[2] to designate this portion of SR 21 in honor of Tom Triplett,^[3] a Democrat who served as Mayor of Port Wentworth and as a State Representative for 18 years. Tom Triplett died in 2006, at 71 years of age.

National Highway System

All of SR 21, except for the Millen Bypass, a bypass around the northeast part of Millen, is included as part of the National Highway System, a system of roadways important to the nation's economy, defense, and mobility.^[4][5]

History

1920s and 1930s

SR 21 was established at least as early as 1919 on its current path from Savannah to Millen, and traveled north-northwest to end in Waynesboro.^[6] By the end of September 1921, it was extended north-northeast to Augusta, replacing a segment of SR 12.^[6][7] By October 1926, US 17/SR 25 was designated on the southern two-thirds of the Chatham County portion of SR 21, but there was no indication if SR 21 was truncated off this segment.^[7][8] In 1930, US 25 was designated on SR 21 from Millen to Augusta.^[9][10] About seven years later, SR 119 was designated on the path of SR 21 southeast of Springfield.^[11][12] At the end of the year, the 1938 GDOT map showed more detail for the highway; it was the first GDOT map that had inset maps for Savannah and Augusta. It showed that US 17/SR 21/SR 25 traveled west-northwest from Savannah on Bay Street. It also showed that US 25/SR 21 entered Augusta on Savannah Road, then began a concurrency with US 1/US 78/SR 4/SR 10/SR 12 (Milledgeville Road), traveled northeast on Twiggs Street, and curved to the north-northeast on 7th Street. At SR 28 (Broad Street), US 1/US 78/SR 4/SR 10/SR 12 traveled east-southeast on it, while US 25/SR 21 traveled west-northwest on it. They turned to the north-northeast on 13th Street to the South Carolina state line. Here, SR 21 ended, and US 25 continued to the north.^[13][14]

1940s and 1950s

Between the beginning of 1945 and November 1946, US 80/SR 26 was shifted onto a concurrency with US 17/SR 21/SR 25 from Savannah to southeast of Industrial City Gardens (Garden City's former name). US 17/SR 25 was shifted off of SR 21 farther to the south-southeast, in Industrial City Gardens. The entire length of SR 21 was hard surfaced.^[15][16] Between April 1949 and August 1950, the path of SR 119 southeast of Springfield was shifted northward, off of the concurrency with SR 21. Its former path that was not concurrent with SR 21 was redesignated as SR 275.^[17][18] By the beginning of 1952, SR 17 was extended on the path of US 17/US 80/SR 21/SR 25 in the Savannah area.^[18][19] Between June 1954 and June 1955, DeRenne Avenue in Savannah was established. A southern bypass of the main part of Augusta was built from US 78/US 278/SR 10/SR 12 on the northeastern edge of Camp Gordon to an interchange with US 25/SR 21 and the northern terminus of SR 56. It was under construction from there east, northeast, and north-northeast to the intersection of Gwinnett Street and 5th Street. US 1/US 78/SR 4/SR 10/SR 12 split off of US 25/SR 21 just north of Gwinnett Street.^[20][21] Between June 1955 and July 1957, US 1/US 25/US 78/SR 4/SR 10, with US 278's then-recent extension, was rerouted onto the previous bypass, which was completed on its previous path and extended a very short distance. SR 4 and SR 21 traveled on their previous alignments.^[21][22]

1960s

Between July 1957 and June 1960, US 25 was rerouted in downtown Augusta. It traveled east-southeast on SR 28 (Broad Street) to the bypass of the city. Its former path was redesignated as US 25 Bus.; however, there was no indication if SR 21 ended at the 7th Street–Broad Street intersection, traveled concurrent with US 25 Bus./SR 28 (west-northwest on Broad Street), or traveled concurrent with US 25/SR 28 (east-southeast on Broad Street).^[22][23] By June 1963, SR 26 Loop was designated on DeRenne Avenue and proposed to travel west-northwest and then north-northeast to US 17/US 80/SR 17/SR 21/SR 26 just northwest of Savannah. The path of SR 121 was extended onto US 25/SR 21 from Millen to Augusta.^[23][24] By the beginning of 1966, SR 26 Loop was proposed to be extended from the La Roche Avenue intersection north-northeast to US 80/SR 26 west-northwest of Thunderbolt. Skidaway Road was established from US 80/SR 26 west-northwest of Thunderbolt south-southwest to DeRenne Avenue. SR 17 was truncated to what is now its northern intersection with US 80/SR 26/SR 30 northwest of Bloomingdale. A western bypass of Sylvania, designated as SR 73 Loop, was proposed from US 301/SR 73 south-southwest of the city to another intersection with those highways north-northwest of it. SR 121 was extended onto the bypass of downtown Augusta, which was then listed as Gordon Highway. SR 21 was indicated to travel on US 25 Bus./SR 28 (Broad Street) and split with it onto 13th Street.^[24][25] In 1966, SR 26 Loop was extended from Montgomery Street to Liberty Parkway and was under construction from there to Augusta Avenue.^[25][26] The next year, its segment from Liberty Parkway to I-16 was indicated to "open Spring '68".^[26][27] In 1968, this segment opened.^[27][28] The next year, SR 26 Loop was opened from I-16 to Augusta Avenue.^[28][29]

1970s

In 1970, SR 26 Loop was proposed to be extended from Augusta Avenue north-northeast and west-northwest to US 17/US 80/SR 21/SR 25/SR 26. SR 73 Loop in the Sylvania area was completed, with US 301 designated on it. The former path of US 301 through the city, on SR 73, was redesignated as US 301 Bus.^[29][30] In 1977, SR 26 Loop was completed on its previous proposed extension.^[31][32] The next year, the entire completed portion of SR 26 Loop, except for the easternmost portion between La Roche Avenue and Skidaway Road, was redesignated as a southeastern extension of SR 21. The portion between La Roche Avenue and Skidaway Road was just decommissioned. SR 21 was also designated on Skidaway Road from US 80/SR 26 west-northwest of Thunderbolt south-southwest to DeRenne Avenue and continued its previous route.^[32][33]

1980s

In 1981, the northern terminus of SR 21 was truncated to the main part of Millen.^[34][35] In 1985, the southern terminus of SR 21 was truncated to its current point at SR 204 (Abercorn Street). I-516 was designated on SR 21 from Montgomery Street in Savannah to Garden City. US 17/SR 25 was routed onto the path of I-516/SR 21 from the Ogeechee Road to the Bay Street interchanges. The former path on Bay Street was redesignated as part of US 17 Alt./SR 25 Alt.^[36][37] In 1988, an unnumbered road was built from SR 21 southeast of Sylvania to US 301/SR 73 at the southern terminus of SR 73 Loop south-southwest of the city.^[38][39] The next year, a northeastern bypass of Millen, designated as SR 828, was proposed from SR 21 east of the city to US 25/SR 121 north-northwest of it.^[39][40]

1990s to 2010s

In 1990, the unnumbered road south of Sylvania was designated as SR 829.^[40][41] In 1993, a western bypass of Springfield, designated as SR 863, was proposed from SR 21 south-southeast of the city to another intersection with SR 21 northwest of it. The path of SR 21 in the Sylvania area was shifted south-southwest, replacing the path of SR 829 and then routed on US 301/SR 73 Loop. Its former path was redesignated as SR 21 Bus.^[42][43] In 1995, the path of SR 21 in the Millen area was shifted northward, replacing the path of SR 828. The path of US 17 in Savannah, north of I-16, was shifted eastward, off of I-516/US 80/SR 21/SR 25/SR 26 and onto I-16 and SR 404 Spur. This rerouting replaced the path of US 17 Alt.^[44][45] In 1997, the path of SR 21 in the Springfield area was shifted westward, replacing the path of SR 863.^[46][47] In 2010, the path of SR 21 in the Newington area was shifted southwestward; its former path was redesignated as SR 21 Bus.^[48][49]

On May 2, 2018, a Lockheed WC-130H transport aircraft of the Puerto Rico Air National Guard crashed and impacted SR 21, near Port Wentworth. A section of SR 21 at the impact site was closed immediately after the incident, and the Air National Guard has provided funds for repairs and cleanup.^[50] {{asof|2018|5}}, traffic is diverted around the crash site to an adjacent road through a temporary detour, until the Georgia Department of Transportation finishes repairs.^[51]

Future

SR 21, as part of the Savannah River Parkway, is proposed to become part of I-3.

Major intersections

Special routes

Garden City spur route

State Route 21 Spur (SR 21 Spur) is a {{convert|1.2|mi|km|adj=mid|-long}} spur route that exists entirely within Chatham County. Part of the highway is in the city limits of Garden City. It is known as Brampton Road for its entire length.

It begins at an intersection with the SR 21 mainline (Augusta Road) in the northeastern part of Garden City, just northwest of the western terminus of Interstate 516 (I-516). It travels to the northeast and intersects SR 25 (Coastal Road), on the edge of the city limits. The highway continues to the northeast and reaches its eastern terminus, Georgia Ports Authority's Gate #2, and the entrance to GAF Materials Corporation, on the Savannah River.^[52]

The path of SR 21 Spur east of the intersection with SR 25 is included as part of the National Highway System, a system of roadways important to the nation's economy, defense, and mobility.^[5]

Between July 1957 and June 1960, SR 21 Spur was established on its current path.^[22][23]

Port Wentworth alternate route

Between the beginning of 2008 and the beginning of 2013, the roadway that would eventually become SR 21 Alt. was proposed as SR 1234 along roughly this same path.^[54][55] In 2016, this roadway was completed.^[55][56] In May 2017, Savannah and nearby Pooler requested that the Jimmy DeLoach Connector be included into the state highway system.^[57]

Chatham County spur route

Springfield business loop

State Route 21 Business (SR 21 Bus.) was a business route of SR 21 that existed in Springfield. Between the beginning of 1997 and the beginning of 2010, it was established on SR 21's former path from SR 21 in the southeastern part of the city to the southern terminus of SR 21 Spur.^[58][59] At least as early as 2015, the business route was decommissioned.^[60]{{notinsource|date=September 2017}}

Springfield spur route

State Route 21 Spur (SR 21 Spur) is a {{convert|0.5|mi|km|adj=mid|-long}} spur route of SR 21 that exists entirely within the central part of Effingham County. The southern terminus of the highway is in the city limits of Springfield. It is known as Old Tusculum Road for its entire length.

It begins at an intersection with SR 119 (North Laurel Street). SR 21 Spur heads to the west-northwest. About {{convert|2500|ft|m}} later, it meets its northern terminus, an intersection with the SR 21 mainline.^[61]

SR 21 Spur is not part of the National Highway System, a system of roadways important to the nation's economy, defense, and mobility.^[4]

Between the beginning of 1997 and the beginning of 2010, it was established from the northern terminus of SR 21 Bus. on SR 119 to SR 21 north-northwest of the city, which is the current path of the highway.^[62][59]

Newington business loop

State Route 21 Business (SR 21 Bus.) is a business route of SR 21 that is entirely within the southeastern part of Screven County. Most of the route is in the city limits of Newington. It is known as Savannah Highway for its entire length.

It begins at an intersection with the SR 21 mainline just southeast of Newington. It travels to the northeast and curves to the northwest to enter the town. It intersects SR 24. It has a brief section that is outside of the city limits before curving to the east and re-entering the city limits. Immediately after, it meets its northern terminus, another intersection with the SR 21 mainline.^[63]

SR 21 Bus. is not part of the National Highway System, a system of roadways important to the nation's economy, defense, and mobility.^[4]

At least as early as 1919, the SR 21 mainline was established on this path.^[6] In 1934, this path had a "completed hard surface".^[64][65] In 2010, the path of SR 21 was shifted southwestward. Its former path was redesignated as SR 21 Bus.^[48][49]

Sylvania business loop

It begins at an intersection with the SR 21 mainline, just southeast of Sylvania. It travels to the northwest and enters the city. Then, it curves to the north-northwest and intersects SR 73 (North Main Street). The two highways travel concurrently to the southwest. They intersect the southern terminus of Maple Street, which is the former SR 21 Conn. When they diverge, SR 21 travels to the northwest. The highway passes Screven County Hospital and Brantley Plaza Shopping Center. Approximately {{convert|0.9|mi|km}} after the northern SR 73 intersection, it meets its northern terminus, an intersection with US 301/SR 21/SR 73 Loop.^[66]

SR 21 Spur is not part of the National Highway System, a system of roadways important to the nation's economy, defense, and mobility.^[4]

At least as early as 1919, SR 21 was established on this path.^[6] In 1937, the path of SR 21 in the southern part of Sylvania had a "completed hard surface".^[67][13] Between the beginning of 1945 and November 1946, the path of the highway in the northern part of the city was hard surfaced.^[15][16] In 1988, an unnumbered road was built from SR 21 southeast of Sylvania to US 301/SR 73 at the southern terminus of SR 73 Loop south-southwest of the city.^[38][39] In 1990, this road south of Sylvania was designated as SR 829.^[40][41] In 1993, the path of SR 21 in the Sylvania area was shifted south-southwest, replacing the path of SR 829 and then routed on US 301/SR 73 Loop. Its former path was redesignated as SR 21 Bus.^[42][43]
