Construction plans for Phase 1 of I-73 South, which extends from I-95 to US Route 501, are currently being finalized. Right of way acquisitions are complete for this segment, and this phase of the project will be shovel ready by the end of 2024.
Right of way plans are complete for Phase 2 of I-73 South, which extends from US 501 to the Marion/Horry County line. Right of way acquisitions are nearly complete for this phase.
Right of way plans are complete for Phase 3 of I-73 South, which extends from the Marion/Horry County line to SC 22. Right of way acquisitions were initiated on the northern section of this phase in early 2024 and will continue throughout the corridor through 2025.
Funding has not been identified to advance construction on any of the three phases of I-73 South.
