A new roundabout interchange is being built at Exit 187 on I‑26 in Berkeley County, South Carolina, where Ridgeville Road (SC‑27) meets the interstate.
What the project includes
- Two roundabouts are being installed just off Exit 187 to manage traffic entering and exiting I‑26 more smoothly than the old four‑way‑stop‑style ramps.
- The work is part of the larger I‑26 widening project between mile markers 187 and 193, which expands the interstate from four to six travel lanes and adds wider shoulders for safety.
Why SCDOT is building it
- SCDOT says these roundabouts improve safety and traffic flow as the area around Ridgeville grows, especially with industrial and commercial development (including the Volvo plant area nearby).
- The department expects drivers across the state to see more of these modern roundabout interchanges replacing traditional signalized or stop‑controlled exits in coming years.
Timeline and impact
- SCDOT currently expects the Exit 187 roundabout interchange and related widening work to be fully completed by this fall (2026).
- During construction, drivers on I‑26 and SC‑27 should expect lane shifts, detours, and temporary closures, with signage in place to guide them around the active work zones.
If you tell me which direction you usually travel (eastbound/westbound I‑26 or along SC‑27), I can outline exactly how the new roundabouts will change your route through Exit 187.
