Georgia State Route 120

Route description

SR 120 begins at an intersection with SR 100 (Bowdon Street) in Tallapoosa, in Haralson County. It heads northeast into Buchanan. Here, it first intersects US 27 Business/SR 1 Business. Then, it meets US 27/SR 1. Just before leaving the county, it enters Draketown, where it intersects SR 113 (Buchanan Highway). The two routes run concurrent to the northeast. In Paulding County, it enters Union. There, they intersect SR 101. At this intersection, SR 113 departs to the north. About 4 miles (6.4 km) miles later, it intersects SR 120 Connector (Scoggins Road). Nearly 4 miles (6.4 km) later, SR 120 enters Dallas. Almost immediately, it meets US 278/SR 6 (Jimmy Campbell Parkway). At this intersection, SR 6 Business (Buchanan Street) east begins and heads northeastward. US 278/SR 6/SR 120 head concurrently to the southeast. At the east end of town is SR 61 (Nathan Dean Boulevard). Farther to the east, in Hiram, the concurrency intersects SR 360 and Bill Carruth Parkway. At this intersection, SR 120/SR 360 head northward on Charles Hardy Parkway. Just over 2,000 feet (610 m) later, they meet SR 6 Business (Atlanta Highway). At Macland Road, SR 360 splits off to the southeast, while SR 120 continues to the northeast. A short distance later, it intersects SR 92 (Hiram Acworth Highway). Approximately 1.5 miles (2.4 km) later, the road enters Cobb County. Just before entering Marietta, the highway passes through Kennesaw Mountain National Battlefield Park. In the central part of the city, it intersects SR 5 and the western terminus of SR 120 Alternate (North Marietta Parkway NW). At this intersection, SR 5/SR 120 head to the southeast. About 1.5 miles (2.4 km) later, they intersect SR 360 (Powder Springs Street). Only a short distance later, the two routes split. To the southeast is Southern Polytechnic State University and then US 41/SR 3 (Cobb Parkway SE). A short distance later is an interchange with Interstate 75 (I-75). To the northeast, the highway meets the eastern terminus of both SR 3 Connector (Roswell Road) and SR 120 Alternate (North Marietta Parkway NE). It crosses over the Willeo Creek into Fulton County. In Roswell, it intersects SR 9 (South Atlanta Street), where they begin a concurrency to the northeast. In the central part of the city, they intersect the eastern terminus of SR 92 (East Crossville Road) and SR 140 (Holcomb Bridge Road). For about a block, SR 140 joins the concurrency, until it departs to the northwest on Houze Road. SR 9/SR 120 pass the North Fulton Hospital, just before entering Alpharetta. In the central part of the city, SR 9 departs to the north on South Main Street, while SR 120 heads eastward on Old Milton Parkway. Farther to the east is an interchange with US 19/SR 400 (Turner McDonald Parkway). In Johns Creek, it meets SR 141 (Medlock Bridge Road). The road crosses over the Chattahoochee River over the Abbotts Bridge and enters Gwinnett County and the Chattahoochee River National Recreation Area. In Duluth is an intersection with US 23/SR 13 (Buford Highway). The route continues to the southeast, until just before it meets I-85. Just before entering Lawrenceville, it meets the southern terminus of SR 317 (Lawrenceville Suwannee Road). Slightly to the southeast, is an interchange SR 316 (University Parkway). The city limits pass within the interchange. SR 120 continues to the southeast until it meets its eastern terminus, an intersection with US 29/SR 8, in the central part of the city.

SR 120 has two sections that are included as part of the National Highway System, a system of roadways important to the nation's economy, defense, and mobility. They are:

History

From 1969 to 2007, SR 120 Loop looped around Marietta. In October 2007, SR 120 Loop was decommissioned, and mainline SR 120 was rerouted to the southern part of the loop. Prior to October 2007, mainline SR 120 ran through downtown Marietta and formed the southern part of Marietta Square. The portion of SR 120 from U.S. 41/SR 3 to SR 120 Alternate was renumbered SR 3 Connector. This was done at the same time changes were made to SR 5.

Dallas–Hiram connector route

State Route 120 Connector (SR 120 Connector) exists within the south-central and southeastern parts of Paulding County.

The route begins at an intersection with the SR 120 mainline (Buchanan Highway) southwest of Dallas, Georgia. It heads east as Scoggins Road to an intersection with SR 61 (Villa Rica Highway) At this intersection, the highway takes the name Hiram Sudie Road. It continues to the east and meets the Bill Carruth Parkway, before it reaches its eastern terminus, an intersection with SR 92 (Hiram Douglasville Highway) on the southwestern edge of Hiram.

SR 120 Connector is not part of the National Highway System, a system of roadways important to the nation's economy, defense, and mobility.

The entire route is in Paulding County.

New Hope–Lost Mountain connector route

State Route 120 Connector (SR 120 Connector) was a route in Paulding County extending from Charles Hardy Parkway (SR 120) to Dallas-Acworth Highway (Old SR 381). It followed what is today East Paulding Drive, formerly known as Dragstrip Road. The former highway crosses SR 92. It was first designated in 1940 as part of SR 176, became SR 92 Connector in 1969 and was last designated SR 120 Connector in 1980.

Marietta alternate route

State Route 120 Alternate (SR 120 Alternate) exists within the central and eastern parts of Marietta. It serves as the northern section of the Marietta Parkway.

It begins at an intersection with the SR 120 mainline (Whitlock Avenue SW) in the central part of the city. At this intersection, SR 120 Alternate is concurrent with SR 5 north of the intersection. The two routes head north and curve to the east and meet US 41/SR 3 (Cobb Parkway SE). Here, SR 5 turns north onto Cobb Parkway, while SR 120 Alternate continues to the east on Marietta Parkway. The road meets an interchange with Interstate 75 (I-75) before curving to the southeast to meet its eastern terminus, an interchange with the eastern terminus of SR 3 Connector (Roswell Road) and the SR 120 mainline.

SR 120 Alternate is not part of the National Highway System, a system of roadways important to the nation's economy, defense, and mobility.

The road that is now SR 120 used to be the northern half of SR 120 Loop, before that designation was decommissioned.

The entire route is in Marietta, Cobb County.

Marietta loop route

State Route 120 Loop (SR 120 Loop) was the former designation of the entire length of the Marietta Parkway, completely within the city limits of Marietta. As its name implies, it was a loop around the center of the city.

These intersections start from the western meeting with the SR 120 mainline and proceed counterclockwise. As a loop, it didn't have actual beginning or ending terminii.
The entire route is in Marietta, Cobb County.
