A question making the rounds ties a road vote in Mount Pleasant to Highway 31 and Georgetown, and asks whether extending one into the other would benefit South Carolina. It is a fair thing to wonder about. It is also built on a mix-up worth clearing up before anything else, because the two highways in that question sit on opposite ends of the state and currently have nothing to do with each other.
Mount Pleasant Town Council appears poised to cast a key vote Tuesday on whether the compromise plan to widen SC Highway 41 should proceed or be delayed, risking the death of the project as planned.
Highway 41 and Highway 31 are two different roads in two different parts of South Carolina. Highway 41 is a Charleston County road, and the widening vote scheduled in Mount Pleasant is a Lowcountry matter with no current bearing on Horry County. Highway 31 — the Carolina Bays Parkway — runs entirely inside Horry County and does not reach Georgetown [Horry County Roads, 2025]. The two roads do not connect, and no agency, regional plan, or reporting proposes connecting them. But should SCDOT and the state consider this?
The South Carolina Department of Transportation (SCDOT) holds a cash balance of $1.89 billion heading into the 2026 fiscal year. Would it benefit the state financially to widen Highway 41 and connect it to the Carolina Bays Parkway extension southern line.
That correction matters, because underneath the garbled premise sits a genuine local story. Horry County is quietly making decisions right now about the future of SC-31 — one to the south, one to the north — and both carry real stakes for the taxpayers who will eventually fund them.
The Charleston Road That Isn’t Ours
The “Highway 41 vote” that keeps surfacing in headlines is real, but it belongs to another region. The roughly $250 million widening of SC-41 in Mount Pleasant, in East Cooper, has been in planning for about nine years and is managed by Charleston County through its half-cent transportation sales tax — not primarily by SCDOT [Live 5 News, 2026].
The project would rebuild the road in a 4-3-4 lane configuration from Clements Ferry Road to US-17, narrowing to three lanes through the historic majority-Black Phillips Community, where residents have raised Gullah-Geechee heritage concerns. About 172 properties are affected, some through eminent domain, and the route cuts into roughly 10 acres of Laurel Hill County Park and about two acres of wetlands [Post and Courier, 2026].
The vote itself is a Mount Pleasant Town Council municipal-consent decision, expected at the council’s July 14, 2026 meeting. The council previously voted 7-1 to oppose the county’s current plan [ABC News 4 WCIV, 2026]. SC-41 is a roughly 121.5-mile state highway linking the Charleston region to the eastern Pee Dee, and it never meets SC-31 [South Carolina Highway 31 — Wikipedia, 2026].
For a Horry County reader, that is the whole point: the vote you may have seen is happening about 130 miles away and changes nothing here.
Exploring the Carolina Bays Parkway Extension
What Highway 31 Actually Is
The Carolina Bays Parkway is Horry County’s own limited-access freeway — about 28 miles of it, running entirely inside the county from SC-707 near Socastee in the south to SC-9 near Little River in the north, paralleling the Intracoastal Waterway around Myrtle Beach [Horry County Roads, 2025]. Its most recent southern segment, extending the road to SC-707, opened November 7, 2019 [South Carolina Highway 31 — Wikipedia, 2026].
It does not enter Georgetown County. The idea that SC-31 runs to, or could soon be pushed into, Georgetown is the second half of the mix-up. There is no pending vote to extend the parkway into Georgetown County [Horry County Roads, 2025].
What does exist is two separate proposed extensions of SC-31 — one heading north toward North Carolina, one heading a short distance south toward the US-17 Bypass. They are distinct projects, at different stages, with different funding sources, and they should not be treated as one.
The Southern Extension: Reserving a Corridor, Not Pouring Concrete
The southern move is the closest thing to a “toward-Georgetown” story, and it needs to be described precisely. On January 27, 2026, Horry County Council’s Transportation Committee advanced an ordinance to add a proposed route — extending SC-31 from SC-707 south to the US-17 Bypass, with a new interchange — to the county’s official map [Post and Courier, 2026].
The purpose is right-of-way preservation, not funded construction. Placing the corridor on the official map lets the county protect the land from development before builders close it off. Assistant County Administrator David Gilreath warned that an open corridor “is not going to be the case soon” [Post and Courier, 2026]. Council members DiSabato and Crawford support the measure, and no organized opposition has been reported.
Two things are worth stressing. First, there is no firm cost or construction timeline; the actual build would likely wait for RIDE IV funding or later [Post and Courier, 2026]. Second, the extension terminates at the US-17 Bypass near the southern Grand Strand — it does not run into Georgetown County. What it does is strengthen US-17, the main artery carrying traffic south toward Georgetown and Pawleys Island [Post and Courier, 2026].
The Northern Extension: A Bigger Project, Now in Flux
The larger and more expensive SC-31 project heads the other direction. The northern extension would carry the parkway from SC-9 across the North Carolina state line toward US-17 in Brunswick County, and Horry County has described it as the road’s final phase [Horry County Roads, 2025]. On the South Carolina side it is funded through the county’s RIDE III sales tax, and it carries the SCDOT designation P029554 and NCDOT designation R-5876 [SCDOT Press, 2025].
That plan hit a wall this spring. On April 22, 2026, NCDOT withdrew support for the jointly preferred cross-state route, citing cost, safety, and environmental concerns [Post and Courier, 2026]. SCDOT is now redesigning its segment, possibly to terminate at the state line. SCDOT spokesperson Kelly Moore says construction remains on track for 2029, with a new design expected in summer 2026 and a public meeting on the updated route in the fall [Post and Courier, 2026]. Public hearings on the earlier plan were held October 20-23, 2025, in Longs, SC and Sunset Beach, NC [SCDOT Press, 2025].
The cost is genuinely unsettled, and the figures do not agree. Reporting has put the full cross-state build at roughly $797 million, with South Carolina’s share around $186 million [Post and Courier, 2026]; the joint NCDOT/SCDOT project materials cite a range of $652 million to $919 million [NCDOT / SCDOT, 2025]; and the Horry County Roads page lists a $125 million budget, which appears to reflect the SC RIDE III allocation rather than the total [Horry County Roads, 2025]. SCDOT’s redesigned South-Carolina-only segment has been described at around $200 million [Post and Courier, 2026]. The honest summary is a range, not a number.
Would It Benefit South Carolina and Horry Taxpayers?
Strip away the geography errors and the underlying question is worth asking: does extending the Carolina Bays Parkway Extension pay off? The case, as laid out for the southern extension, rests on three sourced rationales.
Congestion is the first. The Carolina Bays Parkway Extension already carries about 25,500 vehicles a day, and the South Strand road network is near capacity; an extension would take pressure off the US-17 Bypass, US-17 Business, and SC-707 [Post and Courier, 2026]. Growth is the second. The Socastee and Burgess area added roughly 21,000 residents between 1990 and 2010, and Horry County is projected to exceed 600,000 residents by 2042 [Post and Courier, 2026]. Reserving the corridor now, while the land is undeveloped, is far cheaper than buying built-out property later — which is precisely the taxpayer logic behind the January map ordinance.
Evacuation is the third. SCEMD routes Garden City-area traffic south via US-17 through Georgetown during hurricanes, and added corridor redundancy improves egress when the coast has to empty fast [WMBF News, 2025]. For a county that has watched bumper-to-bumper evacuations up US-501 and US-17, redundancy is not an abstraction.
Here is the taxpayer’s caution. The southern extension is corridor reservation, not a funded road, and every dollar figure attached to the northern extension remains a moving target after North Carolina’s pullout. “Would it benefit SC?” is a reasonable question, but the more useful one for a Horry homeowner is narrower: is reserving the right-of-way now — a low-cost, high-option move — worth it, and separately, is the cross-state northern build worth its still-uncertain price once the redesign lands? The first answers itself on cost-avoidance grounds. The second cannot be answered honestly until SCDOT publishes the new design and a real number this fall.
What to Watch
None of this is settled, and the calendar is short. Watch for SCDOT’s redesigned northern route this summer and the public meeting on it in the fall, both of which will finally attach a firm cost to the state-line segment [Post and Courier, 2026]. Watch whether the full Horry County Council ratifies the January committee’s right-of-way ordinance for the southern extension, and whether it lands on a future RIDE list. And when the next dollar figure appears, read it against the ranges here — because on a project this fluid, the number the county leads with is the one worth checking hardest.
