Part of the current routing of SC 544 was the first route between
Conway and
Myrtle Beach, built in the late 1930s. When the
Intracoastal Waterway was dug, the
swing bridge in
Socastee was also built. US 501 was signed on this route from Conway running south to Socastee. At Socastee, the road followed an east–west direction along the current route of
SC 707 through Socastee, continuing through the area that is currently the
Myrtle Beach International Airport, and ending near downtown Myrtle Beach on the road that is now Broadway Street. A more direct and wider route running diagonally between Conway and Myrtle Beach was built in the early 1960s, replacing SC 503 through the former Conway Bombing and Gunnery Range. US 501 was signed on this path, and SC 544 and SC 707 were created to replace the old route of US 501. A bridge over the Intracoastal Waterway next to the swing bridge was built for a new alignment of SC 544 . Public meetings by the
South Carolina Department of Transportation took place in September 1999 to discuss the widening of SC 544 to a four-lane highway from US 501 in
Conway to the
Intracoastal Waterway, including sidewalks and gutters throughout most of the route. A 90-foot right-of-way was required for the expansion, and the
Federal Highway Administration approved the Finding of No Significant Impact report in January 2000. In February 2001, the road was named in honor of Corporal Dennis Lyden, who was killed on the road in June 2000. Limited areas of six lanes were constructed near the intersection with Phase II of
S.C. Highway 31, approved for construction in January 2002. SC 544 is notable for traversing through many diverse areas of the
Myrtle Beach metropolitan area, including
Coastal Carolina University, several golf courses, many suburban bedroom communities, historic
Socastee, and the tourist-oriented areas near
Surfside Beach and the
Atlantic Ocean. ==Major intersections==
