The Southern Evacuation Lifeline (SELL) is a proposed 28-mile (45 km)[1] limited-access highway in Horry County, South Carolina, in the United States.

It would allow a more direct route west from the southern Strand, while simultaneously completing a beltway around the Myrtle Beach area, connecting with South Carolina Highway 22.

In 2003, a feasibility study showed several possible routes for a road to relieve congestion on major highways in Horry and Georgetown Counties, which would connect U.S. 501 and U.S. 17 by crossing the Waccamaw River.

[4] On February 1, 2005, Horry County added the 701 Connector to RIDE 2, its long-term construction plan, with the intention of providing a hurricane evacuation route.

[6][9][10] Southern Environmental Law Center attorney David Farren opposed building the road across what he called "the area designated for conservation.

DOT project manager Mike Barbee announced in October 2007 that the preliminary environmental impact study was to be released in February 2008.

[14] Nancy Cave of the Coastal Conservation League said a change in the route for Carolina Bays Parkway meant a greater desire for a bridge over the Waccamaw River, which the Coast Guard would have to approve.

[16] The "I-73 Intermediate Traffic and Revenue Study" by C&M Associates, dated February 2016, was to be presented to state transportation officials March 24, 2016 and included upgrades to SC 22.
