South Carolina transportation officials are exploring “choice lanes”—optional toll lanes—to combat worsening traffic congestion on key Lowcountry highways like I-526 and I-26.
Proposal Details
SCDOT Secretary Justin Powell highlighted choice lanes during the March 18, 2026, State of SCDOT meeting, allowing drivers to pay for faster, predictable travel while free lanes benefit from reduced volume. Similar systems operate in Georgia and North Carolina, targeting high-congestion corridors including I-85 (Greenville-Spartanburg) and I-77 (York County).
Lowcountry Focus
I-526’s full rebuild between Mount Pleasant and West Ashley could cost $7 billion, sidelining other projects for 15-20 years. Choice lanes offer a cheaper expansion, potentially cutting free-lane commutes to 26 minutes (from much longer) and toll lanes to 12 minutes.
Legislative Outlook
Lawmakers like Sen. Ed Sutton stressed urgency amid current delays. The concept is early-stage, with studies ongoing but no final toll rates or build sites set, aiming to fund growth without tax hikes.
