 At that time, SC 707 began at Socastee, followed Socastee Boulevard and parts of the then-unbuilt US 17 bypass north of the Myrtle Beach International Airport before terminating at US 501 on the route of the current Robert Grissom 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.
