The South Carolina Highway 22 Extension Project is nearing closer to construction after more than two decades of planning and discussion.
But analyses are still being conducted for residents to weigh in before the project is expected to begin in 2030. Why has it taken so long for the project to be planned, and when will it be completed?
Formerly titled the Southern Evacuation Lifeline project (SELL), the highway intends to improve hurricane evacuation and traffic congestion while aiding services across the Waccamaw River. It’s currently slated to cost $1.56 billion for environmental mitigation and construction funded through Horry County’s RIDE 4 program.
The U.S. Army Corps of Engineers held a series of public meetings in March when residents and stakeholders could voice input on the proposed routes. Residents raised concerns about flooding, traffic near homes, and wetland and habitat destruction, among other issues.
Residents will have another upcoming opportunity to receive information and comment on the next phase of the alternatives screening process, which has considered floodplains, residential and commercial displacement, cultural resources and more.
A pre-recorded presentation of meeting points will be available here beginning Nov. 3, and three drop-in style public meetings are scheduled from Nov. 17-19 from 4 to 6 p.m. each night.
Residents can also submit virtual comments here from Nov. 3 to Dec. 4, 2026.
Historical timeline of the project
The proposed expansion, initially under the SELL name, gained interest in the early 2000s. Twenty-eight routes were considered through a draft environmental impact study, and a preferred route was chosen in 2008. The study recommended the extension should begin at Highway 17 near Surfside Beach, stretching north and east of Conway and ending at U.S. 501 and SC 22.
Since the study was approved, new roadways and residential developments were built in the proposed area and new alternatives needed to be considered, so the project was halted.
In 2023, a conceptual analysis study was completed, and 16 routes were proposed for consideration. An additional six routes were added from public input and suggestions from the Army Corps of Engineers. The 22 routes went through a Tier I Screening to consider how each would provide congestion relief, improve hurricane evacuation and increase accessibility for services to the east and west of the Waccamaw River.
Fifteen of the routes moved to a Tier II Screening process, where they were considered for residential and business displacement, floodplains, cultural resources, impacts to the Waccamaw Wildlife Refuge, farmland, cost and consistency with local and regional land use plans.
The upcoming meetings will discuss the “reasonable alternatives,” which will be fewer than 15 routes. It will also discuss information on the specific environmental and community studies planned for the draft environmental impact statement.
“The core purpose of these meetings is to hear directly from the community about these alternatives and to identify local environmental and community issues that we should consider as the EIS process continues,” Corps spokesperson Dylan Burnell said by email.
Construction is not anticipated until 2030 and is estimated to open in 2035, according to the Corps’ SC-22 website. Information will be updated on the website in early November, Burnell said.
Where are the proposed routes?
The 15 preliminary proposed routes travel south of Conway and connect to the Surfside Beach and Murrells Inlet area, with most slicing through the Bucksport and Burgess communities and crossing the Waccamaw River.
Many residents who attended the previous public input meeting had concerns with the proximity of the routes to the Waccamaw National Wildlife Refuge and other environmentally sensitive areas.
The upcoming meetings will narrow the routes that will be further studied.
How is the project being funded?
Funding for the environmental impact statement and acquired property along the chosen route will be funded through the county’s RIDE 3 Program, which was a 1 cent sales tax approved by Horry County voters in 2016 and expired in 2025 to fund road projects within the county.
Environmental mitigation and construction for the project will be funded through the RIDE 4 Program. Horry County residents voted for a 1% local sales and use tax in 2024 that replaced the RIDE 3 sales tax.
The mitigation and construction is estimated to cost $1.56 billion, and it is the most expensive project approved through RIDE 4.
