South Carolina Highway 901 (SC 901) is a primary state highway in the U.S. state of South Carolina. It serves as a slower alternate rural route to Interstate 77 (I-77) and the western bypass of Rock Hill.
SC 901 begins along SC 200 near I-77. Going north, it hovers to the west and then east of I-77 and then passes through Richburg. After entering York County, it has its own interchange with I-77, then proceeds to form the western bypass of Rock Hill. It is a two-lane rural highway in Fairfield and Chester counties, four lanes wide in York County.
SC 901 in Rock Hill is called Heckle Boulevard because it is named after H.N. Heckle who served as South Carolina Department of Transportation District 4 Construction Engineer during the late 1940s through 1960s.
Established as a new primary routing in 1930 or 1931, it originally ran from SC 9 near Richburg to the York County line. In 1933, it was extended north to U.S. Route 21 (US 21). In 1940, it was extended south to its current southern terminus with SC 22 (today's SC 200). Between 1949-50, it was briefly truncated south at SC 97. Between 1974-79, it was extended north to SC 5. In 1992, it was extended again to its current northern terminus with SC 161/SC 274.
In 2010, SC 901 was widened to four lanes from I-77 to SC 121 funded through the "Pennies for Progress" project fund.
