South Carolina Highway 901 (SC 901) is a 38.730-mile (62.330 km) 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.
Route description
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.[4]
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.[5][unreliable source]
In 2010, SC 901 was widened to four lanes from I-77 to SC 121 funded through the "Pennies for Progress" project fund.[citation needed]
