South Carolina Highway 122 (SC 122), also known as Dave Lyle Boulevard, is a state highway in Rock Hill, York County, South Carolina. It runs about 5.7 miles (9.2 km) from the intersection with West Main Street in Rock Hill and continues west to Waterford Park Drive, also in Rock Hill.

Route description[edit]

SC 122 starts from SC 72 on Johnston Street before exiting just north of the intersection onto Dave Lyle Boulevard. From there, it follows Dave Lyle Boulevard northeasterly, intersecting with SC 5 and further down a full interchange with US Route 21/SC 121. The highway continues on a more easterly course to an interchange with I-77 before terminating at Waterford Park Drive.[2]


The first SC 122 appeared in 1941 or 1942 as a new primary 1-mile (1.6 km) routing from SC 2, in Cayce, to US 1/US 21/SC 2/SC 5, in West Columbia. It was decommissioned in 1948.

The current SC 122 was established as a new primary routing in 1974 or 1975, it went from SC 72 Business east to Interstate 77. In 2001, it was extended to its current eastern terminus at Waterford Park Drive.


Future plans are to construct an extension of SC 122 east into Lancaster County, ending at the US 521/SC 75 intersection; which will connect the Catawba Reservation and provide another crossing over the Catawba River.[3][4]
