# Georgia State Route 42

State Route 42 (SR 42) is a 115.3-mile-long (185.6 km) state highway that runs southeast-to-northwest through portions of Peach, Crawford, Monroe, Butts, Henry, Clayton, and DeKalb counties in the central and north-central parts of the U.S. state of Georgia. The route connects Byron with the Atlanta metropolitan area, via Forsyth, McDonough, and Forest Park.

## Route description

SR 42 begins at an intersection with SR 49/SR 540 (Peach Parkway) in Byron, in Peach County. It stairsteps its way to the west and northwest, crossing into Crawford County along the way. In Knoxville, it intersects US 80/SR 22 (East Crusselle Street). The three highways head concurrent to the west, into Roberta, where they intersect US 341/SR 7 (South Dugger Avenue). Here, SR 42 leaves the concurrency of US 80/SR 22 and joins the concurrency of US 341/SR 7. The three routes travel to the north-northwest into the town of Musella, where SR 42 splits off to the north-northeast and enters Monroe County. In Dyas is an intersection with SR 74. The route continues to the north-northeast, through rural areas of the county and heads toward Forsyth. Just before entering town, it crosses over Tobesofkee Creek. In town, it passes by Forsyth City Cemetery before it has an intersection with US 41/SR 18/SR 83 (Main Street). At this intersection, SR 83 begins a very brief concurrency through parts of town. After the two routes diverge, SR 42 curves to the northwest and parallels Interstate 75 (I-75) for less than 3,000 feet (910 m) before resuming its north-northeast routing and an interchange with I-75. Farther along, it crosses over the Towaliga River. A few miles later, the road enters Butts County. SR 42 passes through Flovilla and intersects US 23/SR 87 just northwest of town. At this intersection, SR 87 reaches its northern terminus and US 23/SR 42 run concurrent for most of the remainder of SR 42's length.
The concurrency heads northwest into Jackson, where they head to the west for a short while. First SR 16, and then SR 36 join and then leave the concurrency. US 23/SR 42 resume their north-northwest routing, passing Sylvan Grove Hospital before leaving town. They curve to the west again, traveling through the town of Jenkinsburg, then enter Henry County. The two routes curve again to the north-northwest and pass through Locust Grove. Then, they enter McDonough, where they intersect SR 155 (North McDonough Road) and then SR 20/SR 81. They pass by Alexander Park before crossing over Camp Creek and leaving town. Then, US 23/SR 42 enter Stockbridge. There, they pass Eagle's Landing Parkway and then head west-northwest on a concurrency with SR 138. The three routes curve to the northwest and reach the end of the concurrency. US 23/SR 42 resume their north-northwest routing and enter Clayton County. The two routes have an interchange with I-675 and then travel through the town of Rex. They skirt along the eastern edge of Fort Gillem and pass by Conley Park, just before entering DeKalb County. US 23/SR 42 meet the northern terminus of SR 54 Conn. (Thurman Road) before an interchange with I-285. They pass to the east of the Lake Charlotte Nature Preserve. After that, they cross over the South River, enter Atlanta, and run along the Fulton–DeKalb county line. They pass by Chestnut Hill Cemetery and meet the eastern terminus of SR 42 Spur (McDonough Boulevard SE). Then, they pass by the western side of Brownwood Park before meeting the western terminus of SR 260 (Glenwood Avenue SE). Just over 1,000 feet (300 m) later is an interchange with I-20. Immediately north of there is SR 154 (Memorial Drive). The two highways travel through the Little Five Points district of the city. They travel through a portion of Freedom Park and meet the eastern terminus of SR 42 Conn. (Freedom Parkway). Just over 1,000 feet (300 m) later, they intersect US 29/US 78/US 278/SR 8/SR 10 (Ponce de Leon Avenue). At this intersection, US 23 splits off to the east, while SR 42 continues to the north. Almost immediately afterward, it curves to the northeast, re-entering DeKalb County proper. Then, it heads fairly northward, passing between Emory University and Herbert Taylor Park and crosses over South Peachtree Creek. It intersects SR 236 (Lavista Road NE). Then, SR 42 turns to the left onto North Druid Hills Road NE. After an interchange with I-85, it meets its northern terminus, an intersection with SR 13 (Buford Highway NE).
The only portion of SR 42 that 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, is from the I-285 interchange east of the southeastern part of Atlanta to the Ponce de Leon Avenue intersection in the eastern part of the city.
