South Carolina Highway 34 South Carolina Highway 34 (SC 34) is a 185.930-mile (299.225 km) primary state highway in the U.S. state of South Carolina. As one of the longer state highways, it traverses the state east-west from Greenwood to Dillon, connecting the cities of Newberry, Winnsboro, Camden, Bishopville and Darlington.
 SC 34 begins as a hidden highway in downtown Greenwood, at the intersection of Main Street and Maxwell Avenue.  On city and state official maps, SC 34 is on an east parallel to U.S. Route 25 Business (US 25 Bus.) and US 178 Bus. along Main Street with some sections being in concurrency; however, no signage identifies this unique relationship, thus the hidden status for 1.6 miles (2.6 km).  At the intersection of Main Street and Ninety Six Highway, the first signage of SC 34 appears, heading east to Ninety Six.
 SC 34 travels through the town of Ninety Six and near the Ninety Six National Historic Site.  Near Newberry, it takes a bypass route along Dixie Drive and Wilson Road, before continuing east to Winnsboro.  Now going southeast, it goes through Ridgeway, to Lugoff, where it overlaps with US 1/US 601 to Camden.  Continuing east and parallel to Interstate 20 (I-20), SC 34 joins with US 15 at Bishopville and skirts north of Lee State Park.  East of Lydia, SC 34 separates from US 15 and goes directly to Darlington.  Heading in a northeasterly direction now, it goes through Brownsville then east into downtown Dillon, where it ends at the intersection of Main Street and Second Avenue.
 An original part of the South Carolina state route system, in 1922 the road ran from Darlington to Ridgeway. In 1933 the road was extended to Dillon and about 1943 a bridge over the Pee Dee river was opened. In September 1951 the road was extended to Greenwood, creating the current configuration. SC 34 was bypassed south around Newberry in 1976 and the original route through the town remained as SC 34 Business. The first part of the road to be paved was the section though Camden in 1929. Over the next several years other parts were paved until the road was fully paved by the early 1940s. During the past several decades, much of the route has been widened to four lanes.
   South Carolina Highway 22 South Carolina Highway 22 (SC 22) was an original state highway that was established on a path from Ninety Six to Newberry. In 1923, it was extended northeast and then east to SC 16 (now U.S. Route 321 (US 321)) in Winnsboro. By the end of 1924, it was extended west-southwest to SC 21 in Greenwood. This extension replaced part of SC 24. By the end of 1926, it was extended to the northeast to end at SC 97 in Great Falls. In September 1951, SC 22 was decommissioned, and most of its path was redesignated as SC 34.
   South Carolina Highway 22 Alternate South Carolina Highway 22 Alternate (SC 22 Alt.) was an alternate route that was established around 1940. It traveled from SC 22 (now US 25 Bus./US 178 Bus.) to US 221/SC 72 in the central part of Greenwood. In 1947, it was decommissioned.
   South Carolina Highway 22 Alternate South Carolina Highway 22 Alternate (SC 22 Alt.) was an alternate route that was established in either 1936 or 1937. It traveled on a loop in Great Falls. In 1947, it was decommissioned and downgraded to secondary roads.
   South Carolina Highway 73 South Carolina Highway 73 (SC 73) was a state highway that was established in 1932 on a path from a point approximately 6 miles (9.7 km) west of Dillon to SC 9 in Dillon. In May 1936, its western terminus was extended to SC 38 in Brownsville. In 1939, it was decommissioned and redesignated as part of SC 34.
   South Carolina Highway 34 Business South Carolina Highway 34 Business (SC 34 Bus.) was established in 1976, following the old mainline route through downtown Newberry, via Boundary Street, College Street, and Main Street. In 2005 the route was decommissioned.[citation needed]

This intersection is also the western terminus of SC 34 Connector (SC 34 Conn.), which takes Lamar Highway to the northeast. They begin a curve to the east-southeast and pass Brockington Elementary School. They have an intersection with SC 340 (known as Timmonsville Highway south of this intersection and Washington Street north of it). They travel through rural areas of the southern part of the city. Then they temporarily leave the city limits of the city and cross over some railroad tracks of the Carolina Piedmont Railroad and Limit Street.
