Do I Need a Palmetto Pass for South Carolina? 2026 Update
No. South Carolina is largely toll-free, and the only active toll road — the Southern Connector (I-185) near Greenville — accepts cash and credit card as well as Palmetto Pass. The savings with Palmetto Pass are modest ($0.20 per full trip).
Key Reality: South Carolina has one of the smallest toll networks in the United States. The Cross Island Parkway (US 278) became permanently toll-free on June 30, 2021, leaving only the 16-mile Southern Connector.
2026 Update: The Southern Connector rates were last adjusted January 2, 2024. Palmetto Pass is not compatible with E-ZPass, SunPass, or other out-of-state transponders. The former Cross Island toll plaza demolition project continues through 2026. No new toll roads are planned statewide.

Frequently Asked Questions
Can I use E-ZPass or other out-of-state tags in South Carolina?
No. Palmetto Pass operates on its own system and is not compatible with E-ZPass, SunPass, NC Quick Pass, or any other state's transponder. Cash or credit card payment is the easiest option for out-of-state visitors.
Is Palmetto Pass worth it?
For most users, no — the savings are $0.20 per full trip, and the pass only works on a single road. Regular commuters on I-185 may benefit from the faster dedicated lane and automatic billing convenience.
Can I avoid the Southern Connector?
Yes. The Southern Connector is a 16-mile spur connecting I-85 and I-385 in Greenville. The parallel toll-free route via I-385 and SC-146 adds approximately 10–20 minutes.
