U.S. Route 90
U.S. Route 90 (US 90) is an east–west United States highway. Despite the "0" in its route number, US 90 never was a full coast-to-coast route; it has always ended at Van Horn, Texas with the exception of a short-lived northward extension to US 62/US 180 near Pine Springs, Texas which lasted less than a year, and the signs on that segment were changed to Texas State Highway 54, traveling from Interstate 10 (I-10) at exit 140A and heading to its northern terminus at US 62/US 180.

SC 90 heads west, first under SC 31, then past numerous housing developments. It also passes in front of North Myrtle Beach Middle School. Upon its intersection with Sea Mountain Highway, much more commercial businesses line the highway. The highway also enters the CDP of Little River at this intersection. Shortly thereafter, Old Highway 17 (unsigned SC 90 Connector) intersects SC 90. It comes to an interchange with US 17 and SC 9, though no access to northbound US 17 / SC 9 is provided at the interchange. For its final , SC 90 passes many businesses before curving to the north and ending at an intersection with US 17.
