Route description

From the eastern terminus at an intersection with U.S. 278, SC 46 travels southwest along Bluffton Road for about 1.6 miles, connecting the newer commercial areas of Bluffton with the original "square mile" or historic town center. SC 46 than makes a right onto May River Road, which it follows for approximately 8 miles until the traffic circle intersection with SC 170. SC 46 is cosigned with SC 170 for about 2.5 miles as it enters Jasper County. The Beaufort County portions of SC 46 are a designated state scenic byway, with marsh vistas and live oak canopies providing a quintessentially Lowcountry feel to the drive.
