All of SR 141 from its southern terminus in Buckhead to a point southwest of Duluth is part of the National Highway System, a system of roadways important to the nation's economy, defense, and mobility.
State Route 141 Connector (SR 141 Conn.) is a 0.9-mile-long (1.4 km) connecting route of SR 141 that exists entirely within the Buckhead section of Atlanta, in eastern Fulton County. It is known as Lenox Road NE for its entire length. It was built in the early 1990s in conjunction with SR 400 to serve area businesses and offices.
It begins at an intersection with the SR 141 mainline (Peachtree Road NE) just northwest of the Buckhead Heights neighborhood of Atlanta. The highway heads northwest, curves to the west-southwest underneath, where it crosses SR 400 (T. Harvey Mathis Parkway) with a single-point urban interchange. It curves to the southwest to meet its northern terminus, an intersection with SR 237 (Piedmont Road NE), at the Buckhead Forest neighborhood of Atlanta.
SR 141 Conn. is not part of the National Highway System, a system of roadways important to the nation's economy, defense, and mobility.
Peachtree Industrial Boulevard is a road in the U.S. state of Georgia that begins in Chamblee and ends in Buford. For approximately four-fifths of its length, Peachtree Industrial Boulevard is not concurrent with SR 141. The section between Interstate 285 (I-285; Atlanta Bypass) and SR 140 (Jimmy Carter Boulevard) and concurrent with SR 141 in Norcross is a freeway. North of SR 140, Peachtree Industrial Boulevard splits from SR 141 and continues to the northeast as a highway with at least four lanes and center median, traveling through the cities of Peachtree Corners, Duluth, Suwanee, Sugar Hill, and Buford. This portion is maintained by Gwinnett County. In the future, the county plans a grade-separation upgrade for the portion between the SR 141 split and Sugarloaf Parkway.
There are six road segments that previously carried State Road 141 or a derivative designation that no longer do.
What is now Georgia SR 371 once was SR 141 between Georgia SR 9 and SR 20. It was changed to its present number in the early 1970s.
The State Road 141 designation was previously used in DeKalb County between Tucker and US 78 in what is now Stone Mountain Park on what is now Hugh Howell Highway (SR 236) which was at the time named Rosser Road.
Prior to construction of Peachtree Parkway and the extension and re-routing of SR141 to Buckhead, SR 141 followed what is present day Medlock Bridge Road from its current intersection with Peachtree Parkway, into downtown Norcross and became North Peachtree Road, crossed the railroad tracks at Park Street, and then traveled on South Peachtree until its terminus at Buford Highway (SR13). When plans were drawn to re-route SR 141 to its present alignment, GDOT changed the designation of this roadway to SR141 Connector. This designation stayed in effect until 1981, when this segment was turned over to the county and converted to local roads. What is now SR 141 between the Buckhead junction with Roswell Rd. (SR9) and Motors Industrial Way (Present day SR 13 Connector) was designated along with Motors Industrial Way as SR 13W before it was made part of the newly aligned SR 141
With the construction of Interstate 85, Norcross Tucker road, which at the time was a contiguous road, was designated SR 141 Connector, and the small segment of South Peachtree Road between Buford Highway and Norcross Tucker Road was redesigned SR 141 Spur. The South Peachtree Road (SR141 Spur) was converted to a local road in 1981 along with truncation of SR141 Connector to Norcross Tucker Road between South Peachtree Rd in Norcross and Interstate 85.
As Jimmy Carter Boulevard was constructed in the 1970s, Norcross Tucker Road was split into North Norcross Tucker Road and South Norcross Tucker Road, and a portion of the road was incorporated into Jimmy Carter Boulevard. In 1981, Jimmy Carter Boulevard was designated as SR 141 Connector between Peachtree Industrial Boulevard and Interstate 85. It was converted to State Road 140 in 1984-1985 timeframe and the SR141 Connector designation was used for what is present day SR141 Connector at the 141/Peachtree Industrial Boulevard interchange when the Jimmy Carter Boulevard/SR141 intersection was upgraded to a grade separated intersection.
The 17.5 mile segment of State Road 369 East of SR 9 from North of Cumming to Gainesville was designated as SR 141 until 1970, when it was extended West to SR 20, and redesigned to its present-day number.
