Frequently Asked Questions

Can I avoid South Carolina tolls completely?

Yes, easily. South Carolina has only one toll road (Southern Connector). You can avoid it by using I-85 to I-26 to I-385, adding about 5-10 minutes to your trip through the Greenville area.

What happened to the Cross Island Parkway tolls?

Cross Island Parkway tolls were eliminated June 30, 2021, after the construction bonds were paid off. The toll plaza is being demolished and the road is now permanently free.

Is Palmetto Pass worth it?

Only if you use the Southern Connector regularly. The savings are modest ($0.20 per trip), so you need 23+ trips annually to break even. For occasional use, cash payment is simpler.

Can I use E-ZPass or other toll tags in South Carolina?

No, only Palmetto Pass works on the Southern Connector. E-ZPass, SunPass, and other toll tags are not compatible with South Carolina's toll system.

What happens if I miss paying a toll?

Fill out a "Pledge to Pay" form and pay within 30 days. After 30 days, you'll receive a violation notice with additional fees. South Carolina doesn't have license plate tolling, so you must pay at the toll plaza.
