Upon crossing US 17, SC 707 continues north into Horry County where construction is proceeding to widen the highway to two lanes in each direction.

SC 707 curves to the northeast and heads through a more wooded area where it passes trailer parks and St. James High School.

[4] Continuing north, a small business district is built up around the intersection of SC 707 and Holmestown Road.

After passing the entrances to additional housing developments, the highway reaches an interchange for the terminus of SC 31 (Carolina Bays Parkway).

Much of the landscape traversed through the area was farmland until the 1980s when suburban growth began to occur outside of Myrtle Beach.

Most of the growth around the area has continued into the 2000s, with development of golf courses, neighborhoods, and subdivisions being common in pockets along the length of the road.

Much of the 9.2-mile (14.8 km) project is being funded through the one-percent Horry County sales tax increase by the 'Riding on a Penny' program.

[8] The intersection of SC 707 with US 17 at Farrow Parkway, known as the "back gate" of the former Myrtle Beach Air Force Base, has seen increased traffic with the construction of The Market Common, expansion of the Myrtle Beach International Airport and other development on and near the former base.

The project also included more turn lanes on US 17, frontage roads, and the addition of Coventry Boulevard as an alternate route around the interchange.
