State Route 42 (SR 42) is a 115.3-mile-long (185.6 km)state highway that runs southeast-to-northwest through portions ofPeach,Crawford,Monroe,Butts,Henry,Clayton, andDeKalbcounties in thecentral and north-central parts of theU.S. state ofGeorgia. The route connectsByron with theAtlanta metropolitan area, viaForsyth,McDonough, andForest Park.
SR 42 begins at anintersection withSR 49/SR 540 (Peach Parkway) inByron, in Peach County. It stairsteps its way to the west and northwest, crossing into Crawford County along the way. InKnoxville, it intersectsUS 80/SR 22 (East Crusselle Street). The three highways headconcurrent to the west, intoRoberta, where they intersectUS 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 ofMusella, where SR 42 splits off to the north-northeast and enters Monroe County. InDyas is an intersection withSR 74. The route continues to the north-northeast, throughrural areas of the county and heads towardForsyth. Just before entering town, it crosses overTobesofkee Creek. In town, it passes by Forsyth City Cemetery before it has an intersection withUS 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 parallelsInterstate 75 (I-75) for less than 3,000 feet (910 m) before resuming its north-northeast routing and aninterchange with I-75. Farther along, it crosses over theTowaliga River. A few miles later, the road enters Butts County. SR 42 passes throughFlovilla and intersectsUS 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 intoJackson, where they head to the west for a short while. FirstSR 16, and thenSR 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 ofJenkinsburg, then enter Henry County. The two routes curve again to the north-northwest and pass throughLocust Grove. Then, they enterMcDonough, where they intersectSR 155 (North McDonough Road) and thenSR 20/SR 81. They pass by Alexander Park before crossing over Camp Creek and leaving town. Then, US 23/SR 42 enterStockbridge. There, they pass Eagle's Landing Parkway and then head west-northwest on a concurrency withSR 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 withI-675 and then travel through the town ofRex. They skirt along the eastern edge ofFort Gillem and pass by Conley Park, just before entering DeKalb County. US 23/SR 42 meet the northern terminus ofSR 54 Conn. (Thurman Road) before an interchange withI-285. They pass to the east of the Lake Charlotte Nature Preserve. After that, they cross over theSouth River, enterAtlanta, and run along theFulton–DeKalb county line. They pass by Chestnut Hill Cemetery and meet the eastern terminus ofSR 42 Spur (McDonough Boulevard SE). Then, they pass by the western side of Brownwood Park before meeting the western terminus ofSR 260 (Glenwood Avenue SE). Just over 1,000 feet (300 m) later is an interchange withI-20. Immediately north of there isSR 154 (Memorial Drive). The two highways travel through theLittle Five Points district of the city. They travel through a portion ofFreedom Park and meet the eastern terminus ofSR 42 Conn. (Freedom Parkway). Just over 1,000 feet (300 m) later, they intersectUS 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 betweenEmory University and Herbert Taylor Park and crosses over South Peachtree Creek. It intersectsSR 236 (Lavista Road NE). Then, SR 42 turns to the left onto North Druid Hills Road NE. After an interchange withI-85, it meets its northern terminus, an intersection withSR 13 (Buford Highway NE).[1]
The only portion of SR 42 that is part of theNational 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.[2][3]
